Higher dimensional communication complexity problems: classical protocols vs quantum ones based on Bell's Theorem or prepare-transmit-measure schemes
Creators: name: Tavakoli, Armin

description: Communication complexity problems (CCPs) are tasks in which separated parties attempt to compute a function whose inputs are distributed among the parties. Their communication is limited so that not all inputs can be sent. We show that broad classes of Bell inequalities can be mapped to CCPs and that a quantum violation of a Bell inequality is a necessary and sufficient condition for an enhancement of the related CCP beyond its classical limitation. However, one can implement CCPs by transmitting a quantum system, encoding no more information than is allowed in the CCP, and extract information by performing measurements. We show that for a large class of Bell inequalities, the improvement of the CCP associated to a quantum violation of a Bell inequality can be no greater than the improvement obtained from quantum prepare-transmit-measure strategies.

description: Principal component analysis is performed on Birkeland or field-aligned current (FAC) measurements from the Active Magnetosphere and Planetary Electrodynamics Response Experiment. Principal component analysis (PCA) identifies the patterns in the FACs that respond coherently to different aspects of geomagnetic activity. The regions 1 and 2 current system is shown to be the most reproducible feature of the currents, followed by cusp currents associated with magnetic tension forces on newly reconnected field lines. The cusp currents are strongly modulated by season, indicating that their strength is regulated by the ionospheric conductance at the foot of the field lines. PCA does not identify a pattern that is clearly characteristic of a substorm current wedge. Rather, a superposed epoch analysis of the currents associated with substorms demonstrates that there is not a single mode of response, but a complicated and subtle mixture of different patterns.

description: A gestão em saúde no período da pandemia Covid-19 caracterizou-se por uma estratégia adotada através de políticas públicas do ministério da saúde que visavam diminuir agravos físicos ou riscos biológicos aos usuários dos serviços assistenciais, bem como a promoção do bem-estar psicossocial dos profissionais prestadores dos cuidados hospitalares. Assim, a gestão de qualidade empregada no período pandêmico buscava enfatizar a participação comunitária para a adoção de medidas preventivas na disseminação do vírus Sars-cov-2, e tornar a equipe multiprofissional participativa no controle de insumos hospitalares e adoção de medidas de biossegurança eficazes contra o vírus. Objetivo: Descrever a importância da gestão de qualidade em saúde pública para contenção da pandemia Covid-19. Métodos: Trata-se de uma revisão integrativa da literatura, com carácter de estudo descritivo e abordagem qualitativa, em que foi realizada buscas no sistema da biblioteca virtual em saúde, utilizando os descritores: Covid-19, gestão em saúde e qualidade da assistência à saúde. Foram incluídos artigos completos, disponíveis na íntegra, produzidos nos períodos de 2019 ao mês de abril de 2023. Os critérios de exclusão foram artigos incompletos, sem conexão com a temática e que não atendiam a linha temporal exigida. Inicialmente foram encontrados 373 resultados sem uso dos filtros, após a aplicação reduziu-se para 154 estudos, e destes, foram lidos os seus títulos restando apenas 11 artigos para a amostra na síntese qualitativa final. Resultados: Diante dos estudos realizados, ficou nítido que a gestão de qualidade tem seu embasamento prático e teórico a partir de um planejamento situacional, que objetiva ampliar a qualidade e resolubilidade da assistência de saúde aos seus usuários acometidos pelo Sars-cov-2, assim como, promover o aperfeiçoamento dos profissionais para lidarem com as adversidades regionais, laborais, psicológicas e financeiras encontradas no cenário pandêmico. Conclusão: Com base nos aspectos analisados, conclui-se que existe a constante necessidade para a implantação de estratégias orçamentárias e políticas voltadas para a prevenção e contenção pandêmicas, objetivando-se proporcionar a melhoria dos padrões de desempenho com produtos e serviços a partir de uma gestão em saúde participativa e cooperativa, que levem em consideração todos os aspectos éticos na prestação dos serviços em saúde.

description: Using infrared spectroscopy combined with ab initio methods we study reactions of H$_2$O and CO inside the confined spaces of Zn-MOF-74 channels. Our results show that, once the water dissociation reaction H$_2$O$\;\rightarrow\;$OH+H takes place at the metal centers, the addition of 40 Torr of CO at 200 $^{\circ}$C starts the production of formic acid via OH+H+CO$\;\rightarrow\;$HCO$_2$H. Our detailed analysis shows that the overall reaction H$_2$O+CO$\;\rightarrow\;$HCO$_2$H takes place in the confinement of MOF-74 without an external catalyst, unlike the same reaction on flat surfaces. This discovery has several important consequences: It opens the door to a new set of catalytic reactions inside the channels of the MOF-74 system, it suggests that a recovery of the MOF's adsorption capacity is possible after it has been exposed to water (which in turn stabilizes its crystal structure), and it produces the important industrial feedstock formic acid.

description: We report our experimental results on phase-sensitive amplification (PSA) in non-degenerate signal-idler configuration using ultra-narrow coherent population oscillations in metastable helium at room temperature. We achieved a high PSA gain of nearly 7 with a bandwidth of 200 kHz, by using the system at resonance in a single-pass scheme. Further, the measured minimum gain is close to the ideal value, showing that we have a pure PSA. This is also confirmed from our phase-to-phase transfer curves measurements, illustrating that we have a nearly perfect squeezer, which is interesting for a variety of applications.

description: The model of self-avoiding lattice walks and the asymptotic analysis of power-series have been two of the major research themes of Tony Guttmann. In this paper we bring the two together and perform a new analysis of the generating functions for the number of square lattice self-avoiding walks and some of their metric properties such as the mean-square end-to-end distance. The critical point $x_c$ for self-avoiding walks is known to a high degree of accuracy and we utilise this knowledge to undertake a new numerical analysis of the series using biased differential approximants. The new method is major advance in asymptotic power-series analysis in that it allows us to bias differential approximants to have a singularity of order $q$ at $x_c$. When biasing at $x_c$ with $q\geq 2$ the analysis yields a very accurate estimate for the critical exponent $γ=1.3437500(3)$ thus confirming the conjectured exact value $γ=43/32$ to 8 significant digits and removing a long-standing minor discrepancy between exact and numerical results. The analysis of the mean-square end-to-end distance yields $ν=0.7500002(4)$ thus confirming the exact value $ν=3/4$ to 7 significant digits.

description: Ramsey theory is an active research area in combinatorics whose central theme is the emergence of order in large disordered structures, with Ramsey numbers marking the threshold at which this order first appears. For generalized Ramsey numbers $r(G,H)$, the emergent order is characterized by graphs $G$ and $H$. In this paper we: (i) present a quantum algorithm for computing generalized Ramsey numbers by reformulating the computation as a combinatorial optimization problem which is solved using adiabatic quantum optimization; and (ii) determine the Ramsey numbers $r(\mathcal{T}_{m},\mathcal{T}_{n})$ for trees of order $m,n = 6,7,8$, most of which were previously unknown.

description: We present here the thermoelectric properties of olivine-type Fe2GeCh4 (Ch = S, Se and Te) using the linear augmented plane wave method based on first principles density functional calculations. The calculated transport properties using the semi-local Boltzmann transport equation reveal very high thermopower for both S and Se-based compounds compared to their Te counterparts. The main reason for this high thermopower is the quasi-flat nature of the bands at the valence and conduction band edges. The calculated thermopower of Fe2GeCh4 is in good agreement with the experimental reports at room temperature, with the carrier concentration around 1018-1019cm-3. All the investigated systems show an anisotropic nature in their electrical conductivity, resulting in a value less than the order of 102 along the a-axis compared to the b- and c-axes. Among the studied compounds, Fe2GeS4 and Fe2GeSe4 emerge as promising candidates with good thermoelectric performance.

description: Tangles of string typically become knotted, from macroscopic twine down to long-chain macromolecules such as DNA. Here we demonstrate that knotting also occurs in quantum wavefunctions, where the tangled filaments are vortices (nodal lines/phase singularities). The probability that a vortex loop is knotted is found to increase with its length, and a wide gamut of knots from standard tabulations occur. The results follow from computer simulations of random superpositions of degenerate eigenstates of three simple quantum systems: a cube with periodic boundaries, the isotropic 3-dimensional harmonic oscillator and the 3-sphere. In the latter two cases, vortex knots occur frequently, even in random eigenfunctions at relatively low energy, and are constrained by the spatial symmetries of the modes. The results suggest that knotted vortex structures are generic in complex 3-dimensional wave systems, establishing a topological commonality between wave chaos, polymers and turbulent Bose-Einstein condensates.

description: We study $^{87}$Rb cold collisions in a static magnetic field and a single-color radio frequency (RF) field by employing the multi-channel quantum defect theory in combination with the Floquet method to solve the two-body time-dependent Schrödinger equation. Our results show that RF fields can modify the two-body scattering length by a large scale through Feshbach resonances both in low and high static magnetic field regimes. Such RF induced Feshbach resonances can be applied to quenching experiments or controlling interactions in spinor condensates. Here, we also show that analogous to photo-association, RF fields can also associate cold atoms into molecules at a useful rate.

Manifestation of the $P$-wave diproton resonance in single-pion production in $pp$ collisions

description: It is demonstrated that many important features of single-pion production in $pp$ collisions at intermediate energies ($T_p \simeq 400$-$800$ MeV) can naturally be explained by supposing excitation of intermediate diproton resonances in $pp$ channels ${}^1D_2$, ${}^3F_3$ and ${}^3P_2$, in addition to conventional mechanisms involving an intermediate $Δ$-isobar. We predict for the first time the crucial role of the ${}^3P_2$ diproton resonance, found in recent experiments on the single-pion production reaction $pp \to pp({}^1S_0) π^0$, in reproducing the proper behavior of spin-correlation parameters in the reaction $pp \to d π^+$ which were poorly described by conventional meson-exchange models to date. The possible quark structure of the $P$-wave diproton resonances is also discussed.

description: We present measurements of the diffusion coefficient of ultrasound in strongly scattering three-dimensional (3D) disordered media using the dynamic coherent backscattering (CBS) effect. Our experiments measure the CBS of ultrasonic waves using a transducer array placed in the far-field of a 3D slab sample of brazed aluminum beads surrounded by vacuum. We extend to 3D media the general microscopic theory of CBS that was developed initially for acoustic waves in 2D. This theory is valid in the strong scattering, but still diffuse, regime that is realized in our sample, and is evaluated in the diffuse far field limit encountered in our experiments. By comparing our theory with the experimental data, we obtain an accurate measurement of the diffusion coefficient of ultrasound in our sample. We find that the value of $D$ is quite small, $0.74 \pm 0.03$ mm$^2/μ$s, and comment on the implications of this slow transport for the energy velocity.

In the paper we establish the global existence of mild solutions to the Cauchy problem on the model for a class of initial data allowed to have large oscillations. The proof is motivated by a recent study of the same topic on the Boltzmann equation in \cite{DHWY}.

description: After centuries of a vibrant English pilgrimage culture, in 1538, Henry VIII outlawed pilgrimage. The prohibition of the practice did not, however, reduce English religious and literary interest in the concept of pilgrimage. Almost a century and a half later, John Bunyan published The Pilgrim's Progress, an allegorical representation of the life of a Christian soul as a physical pilgrimage to heaven. How did the prohibition of pilgrimage allow for Bunyan's concept of pilgrimage to develop? This honors thesis explores how the concept of pilgrimage changed during this period through the writings of English separatists and in popular English literature; it also posits that early modern treatment of this prohibited practice allowed for the return of pilgrimage to modern Anglicanism.

description: Die Entstehung von Überschuldung theoretisch zu erklären ist weitaus schwieriger, als uns medial vermittelt wird. Schulden entstehen nicht plötzlich und auch nicht wegen einem einzelnen Grund. Sie sind vielmehr das Ergebnis länger andauernder Probleme und Nöte der Betroffenen. Auch der rechtliche Rahmen spielt eine Rolle bei der Verschuldung. So verfügen Privatpersonen nicht nur über eine Vielzahl von Verschuldungsmöglichkeiten, wie zum Beispiel bei Kunden- und Kreditkarten, sie können auch ihre Schuldzinsen bei der Steuererklärung als Abzüge von den Einkünften geltend machen. Mit anderen Worten, das Eingehen von Schuldenverpflichtungen ist auch ein Steuersparmodell, das nicht nur Unternehmen und Selbstständigen, sondern auch Privathaushalten zur Verfügung steht.

Long-term sustainability
LTS plan

description: The scope of the Deliverable is to update and release ELIXIR’s Long-term Sustainability Plan (LTS Plan), which is now released as a public document, with a DOI (https://doi.org/10.7490/f1000research.1119412.1) and lives on ELIXIR’s F1000 gateway. Financial sustainability is a key topic for the successful operation of all research infrastructures and a clear, public document that describes the nature of the challenge and details the actions to be carried out to address those is crucial. ELIXIR has had a Long-term Sustainability Plan since 2019, and it is periodically updated and refreshed, taking into account new challenges and opportunities, and the completion of time-specific actions. The aim of ELIXIR’s Long-term Sustainability Plan is to set out short and long-term actions in order to support the sustainability of ELIXIR’s activities, particularly ELIXIR Nodes and the services they run. There are over 400 services run by ELIXIR Nodes and this plan is not intended to act as or replace the need for those services to develop their own sustainability planning. Rather, the document focuses on high-level activities that can best support the long-term sustainability of ELIXIR as a whole, i.e. its capacity to maintain its activities over the long term. The essential purpose and scope of the LTS Plan has not changed in this update: the scope is focussed on ELIXIR overall, not simply the sustainability of the CONVERGE project outputs, even though the Deliverable is carried out through the CONVERGE project. This is because INFRADEV-3, the topic through which ELIXIR-CONVERGE was funded, is there to support the overall operation of research infrastructures. Therefore the scope of the LTS Plan is ELIXIR overall. Similarly, the LTS Plan remains focussed on financial sustainability, rather than environmental sustainability. Indeed, the major change to the LTS Plan since the previous version has been to restructure the document and actions and to bring them in-line with the recommendations made by the European Commission and ESFRI on Long-term Sustainability of Research Infrastructures. Whilst the Deliverable is delayed from the original planned date, work undertaken within ELIXIR in already implementing the actions contained within the LTS Plan has progressed as planned and has indeed remained a higher priority than publishing the final document. For example, now activates focussed on the Sustainability of Nodes through the acquisition of national funding via local roadmaps, and a workshop to bring together ELIXIR partners running services to discuss business models have been prioritised ahead of publishing the LTS plan, as this has a greater impact on ELIXIR overall.

Data Management Plans

description: The overall goal of ELIXIR-CONVERGE’s WP5 was, based on the analysis of a set of very diverse use cases, to contribute to the development of a set of resources supporting the development and implementation of Data Management Plans (DMPs) in national and transnational projects. Six use cases were considered to co-develop and test a method to address domain specific data management planning associated to a set of resources in collaboration with WP1, WP2 and WP3. In this context, another objective of WP5 was to develop, implement and refine key performance indicators (KPIs) in order to monitor the demonstrator projects’ implementation of data management plans and possibly assess their adoption by the relevant community. WP5 developed two sets KPIs in collaboration with WP4, in charge of developing KPIs across the entire ELIXIR-CONVERGE project and for assessing the impact of the project : a first set aiming at monitoring the development of guidance, resources for the development of DMP and for training in the context of the use cases a second set aiming at addressing the adoption of these resources by relevant communities of users as a way to assess the impact of the work achieved In parallel, in order to ensure long term maintenance/update of the developed resources and to increase their impact, WP5 started to engage with ELIXIR communities that could be natural owners of these resources. The KPI developed and collected by WP5 during the ELIXIR-CONVERGE project were useful to follow the partner’s progress in the development and test of a sort of starter kit for domain specific data management support. Success stories could be collected showing adoption by communities and new projects and were mapped on ELIXIR’s categories of impacts showing already “hits” on several of these.

description: We measure the flux density, composition, and energy of outflowing ions above the polar cap, accelerated by quasi-static electric fields parallel to the magnetic field and associated with polar cap arcs, using Cluster. Mapping the spacecraft position to its ionospheric foot point, we analyze the dependence of these parameters on the solar zenith angle (SZA). We find a clear transition at SZA between We find a clear transition at SZA between $\sim$94$^{\circ}$ and $\sim$107$^{\circ}$, with the O$^{+}$ flux higher above the sunlit ionosphere. This dependence on the illumination of the local ionosphere indicates that significant O$^{+}$ upflow occurs locally above the polar ionosphere. The same is found for H$^{+}$, but to a lesser extent. This effect can result in a seasonal variation of the total ion upflow from the polar ionosphere. Furthermore, we show that low-magnitude field-aligned potential drops are preferentially observed above the sunlit ionosphere, suggesting a feedback effect of ionospheric conductivity.

description: Neutrinoless double-beta decay searches seek to determine the nature of neutrinos, the existence of a lepton violating process, and the effective Majorana neutrino mass. The {\sc Majorana} Collaboration is assembling an array of high purity Ge detectors to search for neutrinoless double-beta decay in $^{76}$Ge. The {\sc Majorana Demonstrator} is composed of 44.8~kg (29.7 kg enriched in $^{76}$Ge) of Ge detectors in total, split between two modules contained in a low background shield at the Sanford Underground Research Facility in Lead, South Dakota. The initial goals of the {\sc Demonstrator} are to establish the required background and scalability of a Ge-based, next-generation, tonne-scale experiment. Following a commissioning run that began in 2015, the first detector module started physics data production in early 2016. We will discuss initial results of the Module 1 commissioning and first physics run, as well as the status and potential physics reach of the full {\sc Majorana Demonstrator} experiment. The collaboration plans to complete the assembly of the second detector module by mid-2016 to begin full data production with the entire array.

description: We present results from Johnson $UBV$, Kron-Cousins $RI$ and Washington $CT_1T_2$ photometries for seven van den Bergh-Hagen (vdBH) open clusters, namely, vdBH\,1, 10, 31, 72, 87, 92, and 118. The high-quality, multi-band photometric data sets were used to trace the cluster stellar density radial profiles and to build colour-magnitude diagrams (CMDs) and colour-colour (CC) diagrams from which we estimated their structural parameters and fundamental astrophysical properties. The clusters in our sample cover a wide age range, from $\sim$ 60 Myr up to 2.8 Gyr, are of relatively small size ($\sim$ 1 $-$ 6 pc) and are placed at distances from the Sun which vary between 1.8 and 6.3 kpc, respectively. We also estimated lower limits for the cluster present-day masses as well as half-mass relaxation times ($t_r$). The resulting values in combination with the structural parameter values suggest that the studied clusters are in advanced stages of their internal dynamical evolution (age/$t_r$ $\sim$ 20 $-$ 320), possibly in the typical phase of those tidally filled with mass segregation in their core regions. Compared to open clusters in the solar neighbourhood, the seven vdBH clusters are within more massive ($\sim$ 80 $-$ 380$M_\odot$), with higher concentration parameter values ($c$ $\sim$ 0.75$-$1.15) and dynamically evolved ones.

Sharing viral genome and variation data from around the world helps enable tracking of pathogen evolution, transmission and outbreak investigation, and ultimately contributes to the development of therapeutics. However, it is data mobilisation at scale which truly helps effective genomic surveillance take place. National sequencing centres are often prime candidates for this, as they can generate high volumes of genomic data over a long time period. The scope of this deliverable was to maximise the mobilisation of SARS-CoV-2 sequence and variation data from national sequencing efforts as well as individual centres/labs into the European COVID-19 Data Platform. To achieve this, several aspects of user support were strengthened (including outreach to public health authorities) in addition to continuing the systematic analysis of raw SARS-CoV-2 reads in the INSDC as part of WP8. Through the work described in this deliverable, EMBL-EBI helped support SARS-CoV-2 sequence data streams with national submitters (to encourage open sharing of data beyond SARS-CoV-2). Through WP8 designed analysis workflows, we also generated >3 million variant calls which not only present across the European COVID-19 Data Platform but also other integrated EBI resources for increased visibility and access.

Federated European Genome-phenome Archive

description: This report provides an overview of assessing national use-cases, identifying gaps, and providing recommendations for the future of the Federated European Genome-phenome Archive (FEGA). The assessment focuses on facilitating the adoption of FEGA by ELIXIR National Nodes and 1+MG National Mirror Groups. It presents insights gained from engagement with twelve ELIXIR CONVERGE WP7 partner nodes, twelve nodes involved in other European data sharing initiatives like the European Genome Data Infrastructure and Beyond 1 Million Genomes project, and seven nodes not currently part of these initiatives, including five nodes outside of Europe. Several approaches were taken to address the objectives, including national node use case surveys, individual node check-in meetings, self-assessments against the FEGA Maturity Model, and outreach activities. The node use case surveys collected information from 11 completed surveys, highlighting common data types and user profiles relevant to FEGA. The individual node check-in meetings provided a platform for discussions between Central EGA and ten nodes, covering FEGA node status, challenges, and future plans. Aggregated results from these meetings are included in the report. Nodes were also encouraged to perform self-assessments against the FEGA Maturity Model, and additional feedback was provided through ad hoc meetings. Various outreach activities were coordinated to understand national use cases, identify gaps, and compile recommendations for future FEGA development. These activities were conducted in collaboration with CONVERGE WP7 partners, CONVERGE WP2, and external partners and projects. The report concludes that FEGA is currently supporting the most common use cases in terms of data types and users and has captured the most common challenges. The challenges identified align with the domains in the FEGA Maturity Model, indicating that the model provides a comprehensive framework for meeting these challenges to support node development. Unique use cases and challenges identified by nodes present opportunities for FEGA to fill gaps, such as developing best practices for linking to data in other resources, forming partnerships with biobanking organisations, and promoting the value of FEGA to local governments and national healthcare systems. Overall, the report provides valuable insights into the status of FEGA adoption, identifies gaps and challenges, and offers recommendations for the future roadmap. These findings can inform the further development and expansion of FEGA to support the discovery and access of sensitive human omics and associated data for secondary use.

description: Exchange bias is one of the most extensively studied phenomena in magnetism, since it exerts a unidirectional anisotropy to a ferromagnet (FM) when coupled to an antiferromagnet (AFM) and the control of the exchange bias is therefore very important for technological applications, such as magnetic random access memory and giant magnetoresistance sensors. In this letter, we report the crystal structure manipulation of the exchange bias in epitaxial hcp Cr2O3 films. By epitaxially growing twined (10-10) oriented Cr2O3 thin films, of which the c axis and spins of the Cr atoms lie in the film plane, we demonstrate that the exchange bias between Cr2O3 and an adjacent permalloy layer is tuned to in-plane from out-of-plane that has been observed in (0001) oriented Cr2O3 films. This is owing to the collinear exchange coupling between the spins of the Cr atoms and the adjacent FM layer. Such a highly anisotropic exchange bias phenomenon is not possible in polycrystalline films.

description: By making use of a simple model that captures the key features of the anomalous Maxwell equations, we study the role of inhomogeneities on the evolution of magnetic fields in a chiral plasma. We find that inhomogeneities of the chiral asymmetry by themselves do not prevent the anomaly-driven inverse cascade and, as in the homogeneous case, the magnetic helicity is transferred from shorter to longer wavelength helical modes of the magnetic field. However, we also find that the evolution appears to be sensitive to the effects of diffusion. In the case when diffusion is negligible, the inverse cascade slows down considerably compared to the homogeneous scenario. In the case of the primordial plasma, though, we find that the diffusion is substantial and efficiently suppresses chiral asymmetry inhomogeneities. As a result, the inverse cascade proceeds practically in the same way as in the chirally homogeneous model.

on-site test

description: An increasing number of metal oxide semiconductor (MOS) gas sensors and sensor systems are in use to determine indoor air quality and/or support control of HVAC systems. One benefit of these low-cost MOS gas sensors is, that they are sensitive to a myriad of different volatile organic compounds (VOC). One drawback is that they also react to other gases. Furthermore, chemical properties of many chemical sensors can change during operation due to reversible or irreversible reactions, so drift and poisoning may downgrade the quality of the VOC detector output. At the start of their operation, VOC detectors will typically work within the manufacturer’s speci­fication and deliver reliable results. But how reliable are the results after months or years of operation under a wide variety of atmospheric conditions? This can only be determined through testing. Typical calibration procedures require sophisticated and expensive lab equipment, several gases/gas mixtures and many hours or even days. This is neither suitable for end users nor for installed VOC detectors, e.g. in HVAC systems. This paper suggests some test procedures for VOC detectors to check their performance in the field ranging from very simple “alive tests” to more elaborate “VOC release tests” that can provide a relative or, with more effort, even a quantitative assessment for one or more gases at fairly well-defined concentrations even in the field. This paper is intended as a basis for discussion and exchange of experiences between VOC detector manufacturers, researchers and end users and can be extended to include further test protocols.

Phase-Transition Theory of Kerr Black Holes in Electromagnetic Field

description: For a Kerr black hole (KBH) with spin $J$ and mass $M$ in a steady electromagnetic field, a special Wald vacuum solution (WVS) has been found in the case of no-source uniform field. For WVS, the Meissner effect (ME) occurs only in the the extreme KBH where $M^2/J=1$, in this case, the magnetic field is totally excluded from the event horizon (EH) of KBH. However, WVS does not consider the Hawking radiation (HR) but treats KBH as an absolutely black body. If HR is added , researchers believe that the condition is not so restricted and it is possible for ME to occur in less extreme case. How less is the "less extreme case"? This paper tries to answer this question. Since the Hawking temperature $T_H$ of KBH defined by HR is proportional to the surface gravity $κ$ at the EH, this question is actually about the so-called existence/non-existence of ME (ME/NME) or superconducting phase transition. In this paper, we study the connection between the superconductivity of KBH-EH and the existence of Weyl Fermion (WF). Using thermodynamic formulas and the KBH state equation, we prove that the inherent-parameter condition for ME to occur is $M^2/J\leq ε_c=1.5$ in force-free fields whether it be in the simple axisymmetric vacuum zero source case or in the non-zero source case which can be described by the nonlinear Grad-Shafranov (G-S) equation. We suggest that this is a second-order phase transition and we calculate the critical exponents $δ=1$ and $η=1/2$ for the specific heat diverging at constant $J$, and the critical point $(M_c, Ω_c)$, which equals $(1.22\sqrt{ J}, 0.16/\sqrt{ J})$ where $Ω$ is the angular velocity of KBH. Furthermore we draw the phase diagrams in both $(M, J)$ and $(M,Ω)$ coordinates.

Magnetic mapping of defects in type-II superconductors

description: Recently it was discovered that the non-uniform Meissner current flowing around the pinning sites in the type-II superconductor induces the unconventional vortex-antivortex pairs with the non-quantized magnetic flux [J.-Y. Ge, et al., Nat. Commun. 6, 6573 (2015)]. Here we provide the theory of this phenomenon showing that the vortex-like structures originate from the perturbation of the current streamlines by the non-superconducting defect, which results in the generation of the localized magnetic field. The position and the shape of such vortex dipoles are shown to be very sensitive to the defect form. Thus, applying the external magnetic field or current to the superconductor and using, e.g., the high-resolution scanning Hall microscope to measure the stray magnetic field one can plot the map containing the information about the position of the defects and their shape.

Brauer groups and Galois cohomology of commutative ring spectra

description: In this paper we develop methods for classifying Baker-Richter-Szymik's Azumaya algebras over a commutative ring spectrum, especially in the largely inaccessible case where the ring is nonconnective. We give obstruction-theoretic tools, constructing and classifying these algebras and their automorphisms with Goerss-Hopkins obstruction theory, and give descent-theoretic tools, applying Lurie's work on $\infty$-categories to show that a finite Galois extension of rings in the sense of Rognes becomes a homotopy fixed-point equivalence on Brauer spaces. For even-periodic ring spectra $E$, we find that the "algebraic" Azumaya algebras whose coefficient ring is projective are governed by the Brauer-Wall group of $π_0(E)$, recovering a result of Baker-Richter-Szymik. This allows us to calculate many examples. For example, we find that the algebraic Azumaya algebras over Lubin-Tate spectra have either 4 or 2 Morita equivalence classes depending on whether the prime is odd or even, that all algebraic Azumaya algebras over the complex K-theory spectrum $KU$ are Morita trivial, and that the group of the Morita classes of algebraic Azumaya algebras over the localization $KU[1/2]$ is $\Bbb Z/8 \times \Bbb Z/2$. Using our descent results and an obstruction theory spectral sequence, we also study Azumaya algebras over the real K-theory spectrum $KO$ which become Morita-trivial $KU$-algebras. We show that there exist exactly two Morita equivalence classes of these. The nontrivial Morita equivalence class is realized by an "exotic" $KO$-algebra with the same coefficient ring as $End_{KO}(KU)$. This requires a careful analysis of what happens in the homotopy fixed-point spectral sequence for the Picard space of $KU$, previously studied by Mathew and Stojanoska.

description: Porous polymer membranes via electrostatic complexation triggered by neutralization are fabricated for the first time from a water-soluble poly(ionic liquid) (PIL). The porous structure is formed as a consequence of simultaneous phase separation of the PIL and ionic complexation, which occurred in a basic solution of a non-solvent for the PIL. These membranes have a stimuli-responsive porosity, with open and closed pores in isopropanol and in water, respectively. This property is quantitatively demonstrated in filtration experiments, where water is passing much slower through the membranes than isopropanol.
