description: While Fabry-Perot (FP) resonances and Moire superlattices are intensively studied in graphene on hexagonal boron nitride (hBN), the two effects have not been discussed in their coexistence. Here we investigate the FP oscillations in a ballistic pnp-junctions in the presence and absence of a Moire superlattice. First, we address the effect of the smoothness of the confining potential on the visibility of the FP resonances and carefully map the evolution of the FP cavity size as a function of densities inside and outside the cavity in the absence of a superlattice, when the cavity is bound by regular pn-junctions. Using a sample with a Moire superlattice, we next show that an FP cavity can also be formed by interfaces that mimic a pn-junction but are defined through a satellite Dirac point due to the superlattice. We carefully analyze the FP resonances, which can provide insight into the band-reconstruction due to the superlattice.

description: We present and publish a Mathematica package, which can be used to automatically obtain any numerical MSSM input parameter from SUSY spectrum generators, which follow the SLHA standard, like Spheno, Softsusy, Suseflav or Suspect. The package enables a very comfortable way of numerical evaluations within the MSSM using Mathematica. It implements easy to use predefined high scale and low scale scenarios like mSUGRA or $m_h^{\rm max}$ and if needed enables the user to directly specify the input required by the spectrum generators. In addition it supports an automatic saving and loading of SUSY spectra to and from a SQL data base, avoiding the rerun of a spectrum generator for a known spectrum.

Size Effect on Order-Disorder Transition Kinetics of FePt Nanoparticles

Year: 2013
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: The kinetics of order-disorder transition of FePt nanoparticles during high temperature annealing is theoretically investigated. A model is developed to address the influence of large surface to volume ratio of nanoparticles on both the thermodynamic and kinetic aspect of the ordering process; specifically, the nucleation and growth of L10 ordered domain within disordered nanoparticles. The size- and shape-dependence of transition kinetics are quantitatively addressed by a revised Johnson-Mehl-Avrami equation that included corrections for deviations caused by the domination of surface nucleation in nanoscale systems and the non-negligible size of the ordered nuclei. Calculation results based on the model suggested that smaller nanoparticles are kinetically more active but thermodynamically less transformable. The major obstacle in obtaining completely ordered nanoparticles is the elimination of antiphase boundaries. The results also quantitatively confirmed the existence of a size-limit in ordering, beyond which, inducing order-disorder transitions through annealing is impossible. A good agreement is observed between theory, experiment and computer simulation results.

description: Spatial tailoring of the material constitutive properties is a well-known strategy to mold the local flow of given observables in different physical domains. Coordinate-transformation-based methods (e.g., transformation optics) offer a powerful and systematic approach to design anisotropic, spatially-inhomogeneous artificial materials ("metamaterials") capable of precisely manipulating wave-based (electromagnetic, acoustic, elastic) as well as diffusion-based (heat) phenomena in a desired fashion. However versatile these approaches have been, most designs have so far been limited to serving single-target functionalities in a given physical domain. Here we present a step towards a "transformation multiphysics" framework that allows independent and simultaneous manipulation of multiple physical phenomena. As a proof of principle of this new scheme, we design and synthesize (in terms of realistic material constituents) a metamaterial shell that simultaneously behaves as a thermal concentrator and an electrical "invisibility cloak". Our numerical results open up intriguing possibilities in the largely unexplored phase space of multi-functional metadevices, with a wide variety of potential applications to electrical, magnetic, acoustic, and thermal scenarios.

description: Two designs of a composite marine hatch cover were developed on the basis of the
design of a steel one. One of the proposed designs features composite structure made by
means of manual lay-up technology, and the other one is based on a truss composite structure
which can be produced by rod winding process. Selection of the most rational materials and
design parameters was carried out on the basis of finite element simulations and use of
parametric optimization methods. Results reveal the possibility of weight reduction by means
of using composites in the hatch cover, which is associated, however, with a comparatively
high cost.
Evidence for X(3872) from DD* scattering on the lattice

description: A candidate for the charmonium(like) state X(3872) is found 11 +/- 7 MeV below the DD* threshold using dynamical Nf=2 lattice simulation with J^PC=1^++ and I=0. This is the first lattice simulation that establishes a candidate for X(3872) in addition to the nearby scattering states D D* and J/psi omega, which inevitably have to be present in dynamical QCD. We extract large and negative DD* scattering length a_0=-1.7 +/- 0.4 fm and the effective range r_0=0.5 +/- 0.1 fm, but their reliable determination will have to wait for a simulation on a larger volume. In I=1 channel, only the D D* and J/psi rho scattering states are found and no candidate for X(3872). This is in agreement with the interpretation that X(3872) is dominantly I=0, while its small I=1 component arises solely from the isospin breaking and is therefore absent in our simulation with m_u=m_d.

description: Incoherent photon emission by ultrarelativistic electrons in the normal incidence of a laser pulse on a foil is investigated by means of three-dimensional numerical simulations in the range of intensities $2 \times 10^{21} \text{--} 2 \times 10^{25} \text{W} \, \text{cm}^{-2}$ and electron densities $2 \times 10^{22} \text{--} 1 \times 10^{24} \text{cm}^{-3}$. We focus on properties of the resulting synchrotron radiation, such as its overall energy, directivity of the radiation pattern and slope of the energy spectrum. Regimes of laser-foil interactions are studied in the framework of a simple analytical model. The laser-plasma parameters for efficient gamma-ray generation are found and revealed to be close to the parameters for relativistic foil motion. It is shown that in the case of oblique incidence of a $3 \text{PW}$, $10 \text{fs}$ laser pulse on a thin foil about $10^{8} \text{photons}/0.1\% \text{bandwidth}$ are produced at the energy level of $1 \text{MeV}$ that significantly exceeds performance of the modern Compton gamma-ray sources. Various applications of the gamma-ray bunches are discussed.

Searching for flaring star-planet interactions in AU Mic TESS observations
Creators: name: Ilin, Ekaterina

Publisher: name: Zenodo
Year: 2022

description: AU Mic is a ~23 Myr old, early M dwarf, and the most actively flaring planet host detected to date. Its innermost companion, AU Mic b is a promising target for observations of flaring star-planet interactions (SPI). We used optical light curves of AU Mic obtained by TESS to search for signs of flaring SPI with AU Mic b in the form of excess flares. We find that additional ~50-100 d of TESS-like observations are required to confirm or reject the tentative signal of flaring star-planet interactions in the AU Mic system.

subject: FOS: Physical sciences

description: We build a number of integrable one--scalar spatially flat cosmologies, which play a natural role in inflationary scenarios, examine their behavior in several cases and draw from them some general lessons on this type of systems, whose potentials involve combinations of exponential functions, and on similar non--integrable ones. These include the need for the scalar to emerge from the initial singularity while climbing up sufficiently steep exponential potentials ("climbing phenomenon") and the inevitable collapse in a big Crunch whenever the scalar tries to settle at negative extrema of the potential. We also elaborate on the links between these types of potentials and "brane supersymmetry breaking", a mechanism that ties together string scale and scale of supersymmetry breaking in a class of orientifold models. We show that, under some assumptions that are spelled out in the text, the extended objects of these vacua can inject inflationary phases with discrete values of the spectral index that are determined by the number of unwrapped dimensions of the branes and by the inverse power with which the string coupling $g_s$ enters their world--volume actions. An NS fivebrane, which is interestingly unstable in this class of models, when wrapped on a small internal cycle would yield a spectral index that is amusingly close to the experimentally favored PLANCK value ns ~ 0.96.

The (IR-)relevance of the Gribov ambiguity in SU(2) x U(1) gauge theories with fundamental Higgs matter

description: It is well accepted that dealing with the Gribov ambiguity has a major impact on correlation functions in gauge-fixed Yang-Mills theories, in particular in the low momentum regime where standard perturbation theory based on the Faddeev-Popov approach fails. Recent results, derived from functional tools (Dyson-Schwinger equations or exact RG) or the effective Gribov-Zwanziger action method, pointed towards e.g. gauge boson correlation functions that are not compatible with the properties of observable degrees of freedom. Although such an observation is a welcome feature for gauge theories exhibiting confinement, it would be a discomfort for gauge theories supplemented with Higgs fields, cfr. the experimental success of the electroweak model based on a SU(2) x U(1) gauge group. The purpose of this short note is to assure that the effective action resolution to the Gribov ambiguity reduces to the standard Faddeev-Popov method in the perturbative regime of sufficiently small coupling/large Higgs condensate, thereby not compromising the physical particle spectrum of massive gauge bosons and a massless photon for the SU(2) x U(1) gauge-Higgs model. The closer the theory gets to the limit of vanishing Higgs condensate, the more the Gribov problem resurfaces with all its consequences. We give some speculations w.r.t. the Fradkin-Shenker insights about the phase diagram.

description: A novel 2D finite element (FE) associated with orthogonal finite functions (OFF,
orthogonal splines) was developed for the ANSYS software and was tested early. The
expansion of this method is presented here. The novel 3D FE, connected with 3D OFF is
proposed for modeling and investigation of the stress-strain state of homogeneous and
heterogeneous elastic bodies. The accuracy of the solutions obtained with this 3D FE is as
high as for the classic ANSYS 3D FE. The developed 3D FE requires significantly less
computational time; the winning of computational time increases with the amount of FE in a
model.

description: Motivated by the shift in experimental attention towards electroweak supersymmetric particle production at the CERN LHC, we update in this paper our precision predictions at next-to-leading order of perturbative QCD matched to resummation at the next-to-leading logarithmic accuracy for direct slepton pair production in proton-proton collisions. Simplified models, now commonly adopted by the experimental collaborations for selectrons and smuons as well as mixing staus, are used as benchmarks for total cross sections at achieved and future center-of-mass energies. They are presented together with the corresponding scale and parton density uncertainties in graphical and tabular form for future reference. Using modern Monte Carlo techniques, we also reanalyze recent ATLAS and CMS slepton searches in light of our precision cross sections and for various assumptions on the decomposition of the sleptons and their neutralino decay products.

description: Accessible Science Talks 2022 Annual Science Meeting, Norwich Research Park Illustrating the world of plants and their biotic environment  Lives on earth are living in a close association with other organisms, especially the plant holobiont is a complex system in balancing the beneficial and pathogenic interactions. In contrast to animals, the non-mobile property makes plants more resilient to the surrounding environment. While plants have developed multilayered immune system to protect themselves, as a counter-act, microbes evolved effectors and other strategies to regulate host performance for successful colonization. The crosstalk between host plants and microbes shaped today’s plant biology, ecology, and evolution. We all appreciate plants in our lives: they served as life essentials, as ornamentals, and as a factor in the changing seasons. However, people might never have had a glance into the micro-universe of plants and its associated microbes. With the aid of scientific illustration, the visual communication bridge the gap between technical and conceptual. Researchers could share knowledge and their findings in an accessible approach to a wide range of audiences. This talk introduces the fascinating world of molecular plant-microbe interactions in a pictorial way, plus a brief guide for developing graphical abstracts. About the speaker: Hsuan Pai Pai is a technician at The Sainsbury Laboratory. As a scientist, she helps the team to work on deciphering the plant immune networks. When off from academic, she enjoyed drawing and crafting, and is interested in communicating scientific concepts through illustrations.

description: This is the first paper in a series devoted to systematic study of the size and structure of the broad-line region (BLR) in active galactic nuclei (AGNs) using reverberation mapping (RM) data. We employ a recently developed Bayesian approach that statistically describes the variabibility as a damped random walk process and delineates the BLR structure using a flexible disk geometry that can account for a variety of shapes, including disks, rings, shells, and spheres. We allow for the possibility that the line emission may respond non-linearly to the continuum, and we detrend the light curves when there is clear evidence for secular variation. We use a Markov Chain Monte Carlo implementation based on Bayesian statistics to recover the parameters and uncertainties for the BLR model. The corresponding transfer function is obtained self-consistently. We tentatively constrain the virial factor used to estimate black hole masses; more accurate determinations will have to await velocity-resolved RM data. Application of our method to RM data with Hbeta monitoring for about 40 objects shows that the assumed BLR geometry can reproduce quite well the observed emission-line fluxes from the continuum light curves. We find that the Hbeta BLR sizes obtained from our method are on average ~20% larger than those derived from the traditional cross-correlation method. Nevertheless, we still find a tight BLR size-luminosity relation with a slope of alpha=0.55\pm0.03 and an intrinsic scatter of ~0.18 dex. In particular, we demonstrate that our approach yields appropriate BLR sizes for some objects (such as Mrk 142 and PG 2130+099) where traditional methods previously encountered difficulties.

description: We have systematized possible ways of forming the isomers of mini-fullerenes,
namely elementary fullerenes: tetrahedron C4, triangular prism C6, cube C8, pentagonal prism
C10, hexagonal prism C12, as well as their derivatives, which were obtained by joining
elementary fullerenes. Combined with the graph analysis, this approach allows obtain a clear
knowledge of their structure. Among them there are barrel-shaped fullerenes: C12, C16, C20;
tetrahedral ones C12 and C16; bi-shamrocks C14 and C18, bipyramids C14 and C18; regular and
irregular dodecahedrons C20 as well as intermediate compounds. The three simplest
elementary fullerenes, C4, C6, C8; have only electronic isomers and no space atomic isomers
at all. After a cube, the next in size carbon fullerene C10 is a pentagonal prism. We have
designed an isomer of it by fusion of a tetrahedron and a triangular prism. For the pentagonal
prism shape fullerene the energy lies in the range from 974 to 2464 kJ/mol, for the hybrid of a
tetrahedron and a triangular prism does in the range from 1396 to 2433 kJ/mol; it depends
both on the number of single and double bonds as well as on their position in space. Fullerene
of twelve carbon atoms C12 produces four isomers: a hexagonal prism, a barrel-shape
fullerene, a truncated tetrahedron and a tetra-penta octahedron. They have different energies
depending on the number of single and double bonds and their position in space. In a like
manner other fullerenes studied, C14, C16, C18 and C20, have two or three isomers with
different energies.

description: Galaxy formation models and simulations rely on various feedback mechanisms to reproduce the observed baryonic scaling relations and galaxy morphologies. Although dwarf galaxy and giant elliptical properties can be explained using feedback from supernova and active galactic nuclei, Milky Way-sized galaxies still represent a challenge to current theories of galaxy formation. In this paper, we explore the possible role of feedback from stellar radiation in regulating the main properties of disk galaxies such as our own Milky Way. We have performed a suite of cosmological simulations of the same $\sim10^{12} {\rm M}_{\odot}$ halo selected based on its rather typical mass accretion history. We have implemented radiative feedback from young stars using a crude model of radiative transfer for ultraviolet (UV) and infrared (IR) radiation. However, the model is realistic enough such that the dust opacity plays a direct role in regulating the efficiency of our feedback mechanism. We have explored various models for the dust opacity, assuming different constant dust temperatures, as well as a varying dust temperature model. We find that while strong radiative feedback appears as a viable mechanism to regulate the stellar mass fraction in massive galaxies, it also prevents the formation of discs with reasonable morphologies. In models with strong stellar radiation feedback, stellar discs are systematically too thick while the gas disc morphology is completely destroyed due to the efficient mixing between the feedback-affected gas and its surroundings. At the resolution of our simulation suite, we find it impossible to preserve spiral disc morphology while at the same time expelling enough baryons to satisfy the abundance matching constraints.

description: We investigate the transport through a few-level quantum system described by a Markovian master equation with temperature- and particle-density dependent chemical potentials. From the corresponding Onsager relations we extract linear response transport coefficients in analogy to the electronic conductance, thermal conductance and thermopower. Considering ideal Fermi and Bose gas reservoirs we observe steady-state currents against the thermal bias as a result of the non-linearities introduced by the constraint of a constant particle density in the reservoirs. Most importantly, we find signatures of the on-set of Bose-Einstein condensation in the transport coefficients.

description: We have systematized possible ways of forming the isomers of midi-fullerenes,
namely C22, C24, C26 and C28. There are three the most natural mechanisms of their obtaining:
embedding carbon dimers into initial fullerenes; fusion of carbon cupolas having the same
symmetry; fusion of fullerenes having compatible symmetry. The minimum energy fullerenes
are obtained through the use of the first mechanism. It is worth noting that these fullerenes
conserve the topological three-fold symmetry. At the same time the graph representation
shows the change of symmetry from three-fold symmetry to six-fold one. Combined with the
graph analysis, this geometric modeling allows obtain a clear knowledge of the structure of
the fullerenes formed.

description: *** To appear in Theory and Practice of Logic Programming (TPLP) *** Within the context of constraint solving, a portfolio approach allows one to exploit the synergy between different solvers in order to create a globally better solver. In this paper we present SUNNY: a simple and flexible algorithm that takes advantage of a portfolio of constraint solvers in order to compute --- without learning an explicit model --- a schedule of them for solving a given Constraint Satisfaction Problem (CSP). Motivated by the performance reached by SUNNY vs. different simulations of other state of the art approaches, we developed sunny-csp, an effective portfolio solver that exploits the underlying SUNNY algorithm in order to solve a given CSP. Empirical tests conducted on exhaustive benchmarks of MiniZinc models show that the actual performance of SUNNY conforms to the predictions. This is encouraging both for improving the power of CSP portfolio solvers and for trying to export them to fields such as Answer Set Programming and Constraint Logic Programming.

description: We present an extensive quantum Monte Carlo study of the Néel-valence bond solid (VBS) phase transition on rectangular and honeycomb lattice SU($N$) antiferromagnets in sign problem free models. We find that in contrast to the honeycomb lattice and previously studied square lattice systems, on the rectangular lattice for small $N$ a first order Néel-VBS transition is realized. On increasing $N\geq 4$, we observe that the transition becomes continuous and with the {\em same} universal exponents as found on the honeycomb and square lattices (studied here for $N=5,7,10$), providing strong support for a deconfined quantum critical point. Combining our new results with previous numerical and analytical studies we present a general phase diagram of the stability of $\mathbb{CP}^{N-1}$ fixed points with $q$-monopoles.

description: Nonlinear optical excitation of infrared active lattice vibrations has been shown to melt magnetic or orbital orders and to transform insulators into metals. In cuprates, this technique has been used to remove charge stripes and promote superconductivity, acting in a way opposite to static magnetic fields. Here, we show that excitation of large-amplitude apical oxygen distortions in the cuprate superconductor YBa2Cu3O6.5 promotes highly unconventional electronic properties. Below the superconducting transition temperature (Tc = 50 K), interbilayer coherence is transiently enhanced at the expense of intra-bilayer coupling. Strikingly, even above Tc a qualitatively similar effect is observed up to room temperature, with transient inter-bilayer coherence emerging from the incoherent ground state and similar transfer of spectral weight from high to low frequency. These observations are compatible with previous reports of an inhomogeneous normal state that retains important properties of a superconductor, in which light may be melting competing orders or dynamically synchronizing the interlayer phase. The transient redistribution of coherence discussed here could lead to new strategies to enhance superconductivity in steady state.

description: We have systematized possible ways of forming the isomers of midi-fullerenes,
namely C30, C32, C34 C36, C38 and C40. Similar to the isomers of midi-fullerenes from C20 to
C28, there are three the most natural mechanisms of their formation: 1) Embedding carbon
dimers into initial fullerenes; 2) Fusion of carbon cupolas having the same symmetry; and 3)
Fusion of fullerenes having compatible symmetry. The energies of the fullerenes calculated
through the use of molecular mechanics are presented together with their graphs. It is found
that in the majority of cases the minimum-energy fullerenes are those, having perfect and
topological three-fold symmetries.
Beyond random effects: When small-study findings are more heterogeneous

description: Using new meta-regression methods, we investigate whether small-study findings are more heterogeneous. If they are, the random-effects model is invalid and an alternative, the unrestricted weighted least squares, statistically dominates random effects. Here, we provide the data and code used in our paper, “Beyond random effects: When small-study findings are more heterogeneous.” The code is given in the Supplement.

description: We investigate the analogy between the large N expansion in normal matrix models and the asymptotic expansion of the determinant of the Hilb map, appearing in the study of critical metrics on complex manifolds via projective embeddings. This analogy helps to understand the geometric meaning of the expansion of matrix model free energy and its relation to gravitational effective actions in two dimensions. We compute the leading terms of the free energy expansion in the pure bulk case, and make some observations on the structure of the expansion to all orders. As an application of these results, we propose an asymptotic formula for the Liouville action, restricted to the space of the Bergman metrics.

description: We have considered the following classical fullerenes: C40 C84 and C92. All of them
have tetrahedral symmetry. The nonclassical fullerenes C64 and C76 were proposed earlier.
Now, we have outlined a constructive process to obtain both fullerenes. The Table obtained
earlier is complemented with four nonclassical fullerenes C52, C60, C88, and C100. The mass
difference Δm between the numbers of carbon atoms of the fullerenes forms the sequence: 8,
4, 12, 8, 4, 12, 8, 4, 12. Its periodicity has no gaps as before.

description: The multiparameter analysis of simultaneous optical data for systems of
nano- and/or micro-particles (3D disperse systems, dispersions, colloids, ensembles with the
average diameter less than 10 micrometers) can be presented as the system characteristics
characterized by N-dimensional unique vectors of optical parameters that can elucidate
changes in the state of system particles. The application of ND unique optical vector approach
is shown for several biomedical dispersions at the processes of aggregation. This approach can
serve as the online control platform for the management of technological processes with 3D
disperse systems.

description: Curated scientific databases play an important role in the scientific endeavour and support is needed for the significant effort that goes into their creation and maintenance. This demonstration and case study illustrate how curation support has been developed in the Links cross-tier programming language, a functional, strongly typed language with language-integrated query and support for temporal databases. The chosen case study uses weekly released Covid-19 fatality figures from the Scottish government which exhibit updates to previously released data. This data allows the capture and query of update provenance in our prototype. This demonstration will highlight the potential for language-integrated support for curation to simplify and streamline prototyping of web-applications in support of scientific databases.

description: Mohandas Karamchand Gandhi, genannt Mahatma Gandhi, hat Satyagraha als politisches Instrument nicht erfunden. Seine Auseinandersetzung mit einer angemessenen Antwort auf soziale und politische Ungerechtigkeit war beeinflusst von Erfahrungen und Diskussionen im angelsächsischen Raum, reflektiert durch seine eigene Biographie und kulturelle Erfahrung. Daher beginnt oder endet die Diskussion über Satyagraha als Instrument politischer Aktion nicht mit Gandhi. Dieser war es jedoch, der Satyagraha konzeptionell schärfte und einer Reihe von Aktivisten und Bewegungen so erst verfügbar machte.
