Non-Markovian Dynamics of Spin Squeezing
Creators: name: Xue, Peng
Publisher: name: arXiv
Year: 2012
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: We evaluate the spin squeezing dynamics of N independent spin-1/2 particles with exchange symmetry. Each spin interacts with its own reservoir, and the reservoirs are independently and identical. The spin squeezing parameter is analytically calculated with different kinds of decoherence. The spin squeezing property vanishes with evolution time under the Markovian decoherence. Whereas coupled to the non-Markovian decoherence channels, the spin squeezing property collapses and revives with time. As spin squeezing can be regarded as a witness of multipartite entanglement, thus our scheme shows the collapse and revival of multipartite entanglement under non-Markovian decoherence.

description: Using density functional theory (DFT)-based calculations, we propose a family of metastable, as-yet unmade V5+ and Cr6+ double perovskite compounds with low band gaps spanning much of the visible region of the solar spectrum. Through analysis of a related set of measured optical gaps of d0 ABO3 perovskites and A2B'BO6 double perovskites, an ad hoc procedure is developed to correct DFT and many-body perturbation theory gaps, bringing them into quantitative agreement with experiment for measured compounds, and predicting that V5+ and Cr6+ double perovskites would have gaps ranging from approximately 1.1-2.4 eV, significantly lower than previous materials studied in this class. DFT calculations also establish that these V5+ and Cr6+ compounds are likely able to be synthesized, either in bulk form or as epitaxial thin films. These compounds would comprise a new class of semiconducting double perovskites for potential use in solar energy conversion and other optoelectronic applications.

The semiclassical limit of W_N CFTs and Vasiliev theory

description: We propose a refinement of the Gaberdiel-Gopakumar duality conjecture between W_N conformal field theories and 2+1-dimensional higher spin gravity. We make an identification of generic representations of the W_N CFT in the semiclassical limit with bulk configurations. By studying the spectrum of the semiclassical limit of the W_N theories and mapping to solutions of Euclidean Vasiliev gravity at λ=-N, we propose that the `light states' of the W_N minimal models in the 't Hooft limit map not to the conical defects of the Vasiliev theory, but rather to bound states of perturbative scalar fields with these defects. Evidence for this identification comes from comparing charges and from holographic relations between CFT null states and bulk symmetries. We also make progress in understanding the coupling of scalar matter to sl(N) gauge fields.

description: We present a fast phase gate scheme that is experimentally achievable and has an operation time more than two orders of magnitude faster than current experimental schemes for low numbers of pulses. The gate time improves with the number of pulses following an inverse power law. Unlike implemented schemes which excite precise motional sidebands, thus limiting the gate timescale, our scheme excites multiple motional states using discrete ultra-fast pulses. We use beam-splitters to divide pulses into smaller components to overcome limitations due to the finite laser pulse repetition rate. This provides gate times faster than proposed theoretical schemes when we optimise a practical setup.

description: The opinions of why the need for food supplements has changed throughout time are included in this study. In addition, the methods for producing dietary supplements were examined, as well as the advantages and disadvantages of each method. Food supplements and their role in natural nutrition, as well as their impact on human health, should be studied holistically rather than isolated from natural sources. Thousands of different chemical additives, microbial and biotechnological applications, and other technological processes turn a natural product into a malady. Many faults of research and development (R&D) project findings of dietary supplements might become more clearly known when studies are conducted with a holistic view.

description: An extensive analysis of an optically-thin, dry atmosphere at different values of the thermal Rossby number Ro and of the Taylor number Ff is per- formed with a general circulation model by varying the rotation rate Ω and the surface drag τ in a wide parametric range. By using nonequilibrium thermodynamics diagnostics such as material entropy production, efficiency, meridional heat transport and kinetic energy dissipation we characterize in a new way the different circulation regimes. Baroclinic circulations feature high mechanical dissipation, meridional heat transport, material entropy pro- duction and are fairly efficient in converting heat into mechanical work. The thermal dissipation associated with the sensible heat flux is found to depend mainly on the surface properties, almost independent from the rotation rate and very low for quasi-barotropic circulations and regimes approaching equa- torial super-rotation. Slowly rotating, axisymmetric circulations have the highest meridional heat transport. At high rotation rates and intermediate- high drag, atmospheric circulations are zonostrohic with very low mechanical dissipation, meridional heat transport and efficiency. When τ is interpreted as a tunable parameter associated with the turbulent boundary layer trans- fer of momentum and sensible heat, our results confirm the possibility of using the Maximum Entropy Production Principle as a tuning guideline in the range of values of Ω. This study suggests the effectiveness of using fun- damental nonequilibrium thermodynamics for investigating the properties of planetary atmospheres and extends our knowledge of the thermodynamics of the atmospheric circulation regimes.
Scaling Small: The Open Book Collective Launch and Platform

description: Presentation delivered by Judith Fathallah at OTESSA 2023, 2 June 2023.
Abstract: The Open Book Collective, scheduled to launch November 2022, brings together Open Access book publishers, scholarly librarians, and OA infrastructure providers, working towards a sustainable and equitable future for OA books. This session will introduce our work, then demonstrate the use of the Open Book Collective membership platform, which will be live by the time of the conference. The Open Book Collective operates according to the principle of Scaling Small, which has guided the work of its umbrella project, Community-Led Open Infrastructures for Open Access Books (COPIM). 'Scaling Small', as opposed to 'scaling up', is an alternative way of envisaging a publishing and distribution ecosystem for Open Access Books that is based on mutual reliance and other kinds of collaboration rather than competition and incorporation. We believe that economies of scale flatten community diversity and lead to unhealthy monopolies. More pragmatically, the OBC requires a commitment from our publisher members to move away from book processing charges, which are both unsustainable and deeply inequitable. The introduction and interactive demonstration will be followed by a Q and A.
Prevent Devastating Hail Storms, Flash Floods, Tornadoes, Tsunami, by Eradicating Global Abortion, and Reversing Contraception: A Retrospective Analysis

Subjects: Aborted blood pollution

putrefaction of enormous fetuses

description: Back ground: The period of contraception and abortion [mid-twentieth and early-twentieth centuries] saw a rise in the frequency of hail storms, tornadoes, flash floods, and tsunamis; as a result, an altruistic analysis of any link between increasing natural disaster trends and contraception, abortion, was planned for the past 4-5 decades, by analysing the environmental pollutant. Methods: The occurrence of hail storms, flash floods, tornadoes, and tsunami, was timed with the gradual and stealthy implementation of global contraception and abortion. Environmental pollutants, including as estrogen, alpha feto [1] protein, and beta human chorionic gonadotropin, were measured in rivers and oceans and associated with the results. Three samples of river water around Cape Comorian were tested for Estrogen, as were four samples of sea water from four distinct seas: Indian Ocean, Arabian Sea, Bay of Bengal near cape, and Bay of Bengal near Union Territory. Estimation of Fetal, adult hemoglobin in sea water was attempted by routine hemoglobin electrophoresis. Estimation of alpha feto protein and β Human chorionic gonado tropin in river and sea water was undertaken Results: Over the last 4-5 decades, there has been a 2.5-fold rise in hail storms, flash floods, tornadoes, [p<0.01] , and a 6-fold rise [p <0.0005] in tsunami. Earlier estimates [1] of estrogen, alpha feto protein, beta human chorionic gonado tropin in rivers, oceans showed their presence as follows Estrogen was detected in river water- 3-5pg/ml and sea water - 0.3-1pg/ml. Alpha feto protein was detected in sea, river water as <0.6ng/ml, β human chorionic gonado tropin was detected in sea and river water as <0.1miu/ml confirming further, aborted blood pollution of the sea, river. It was also in the rivers, which were diluted in the oceans. Hemoglobin could not be detected in water samples since the technology could only detect in grams, but oestrogen could only be estimated in pg. Conclusion: Contraceptive menstrual blood pollution, or aborted blood pollution of the waterways, as demonstrated by estrogen, alpha fetoprotein, and beta human chorionic gonadotropin, depletes oxygen in rivers and oceans, which cannot be replaced by plants depleting ozone, combined with putrefaction of enormous fetuses [2] producing toxic, inflammable, explosive gases, resulting in increased trends of tornadoes, flash floods, hail storms, tsunamis.

description: In human-machine interaction, muscle activity
serves as an indicator of the human motion intent and is mostly
assessed using electromyography (EMG). EMG requires special
skin preparation, accurate electrode placement, and is affected
by sweating. In contrast, force myography (FMG) measures the
mechanical muscle contraction, thereby promising reliable longterm
acquisition for gait phase detection. With one individual
piezoelectric sensor patch per muscle, reduced cross-talk around
the limb circumference is expected compared to state-of-theart
elastic straps comprising several sensors linked together.
In this work, seven physically unimpaired participants wore
four 3D-printed, highly sensitive ferroelectret sensors along with
four EMG electrodes on the lower limbs while walking on an
instrumented treadmill at normal walking speed. Tibialis anterior
(TA) and vastus medialis (VM) are best suited for heel strike and
toe-off detection with the FMG sensors to discriminate between
swing and stance phases. The signal variability across all strides
is exceptionally low. The characteristic FMG peaks differ from
the ground reaction force reference by 3.6% ± 2.0% of the stride
time for TA and 1.2% ± 1.2% for VM. Using the customizable
ferroelectret sensors, this FMG system provides a substitute or
supplement in sensor fusion for conventional EMG.

description: We compute the two-point correlation functions for the spin-3 theory in three dimensional (Anti-) de Sitter spacetimes by using holographic renormalisation. For the AdS case, we find results consistent with the general requirements of two-dimensional conformal invariance. In the de Sitter case, we find similar results. We discuss consistency requirements on the three point functions TWW for our results to be compatible with the asymptotic symmetry algebra for AdS case and with the de-Sitter central charge found in hep-th/0106113 by analyzing the stress-tensor. We also discuss why it is very likely that our results are not compatible with the imaginary central charge previously found for higher-spin theories in dS(3).

description: A classification of phenomenologically interesting supersymmetric extensions of the Standard-Model with a $U(1)_R$ symmetry is presented. Some of these are consistent with subsets of leptonic or baryonic "R-parity violating" (RPV) operators, thereby providing a natural motivation for them. We then focus on a particular class of models in which the $U(1)_R$ symmetry coincides with lepton number when restricted to the SM sector. In this case, the extension of lepton number to the superpartners is "non-standard", implying, in particular, the existence of the leptonic RPV operators $LLE^c$ and $LQD^c$, and a vacuum structure where one of the left-handed sneutrinos acquires a significant vacuum-expectation-value, while not being constrained by neutrino mass bounds. The model can be naturally consistent with bounds from electroweak precision measurements and flavor-changing processes. It can also easily accommodate the recently measured Higgs mass due to the existence of a scalar triplet that couples to the Higgs with an order one coupling, with only moderate fine-tuning. The phenomenology is rather rich and distinctive, with features such as heavy-but-natural Dirac gauginos, relaxed bounds on squarks, resonant slepton/sneutrino production, lepto-quark signals, as well as an interesting connection to neutrino physics arising from R-breaking. The broad qualitative features are discussed in this paper, with a more detailed phenomenological study carried out in a companion paper Frugiuele et al. (2012).

Height of exceptional collections and Hochschild cohomology of quasiphantom categories

Subjects: subject: Algebraic Geometry (math.AG)

description: We define the normal Hochschild cohomology of an admissible subcategory of the derived category of coherent sheaves on a smooth projective variety $X$ --- a graded vector space which controls the restriction morphism from the Hochschild cohomology of $X$ to the Hochschild cohomology of the orthogonal complement of this admissible subcategory. When the subcategory is generated by an exceptional collection, we define its new invariant (the height) and show that the orthogonal to an exceptional collection of height $h$ in the derived category of a smooth projective variety $X$ has the same Hochschild cohomology as $X$ in degrees up to $h - 2$. We use this to describe the second Hochschild cohomology of quasiphantom categories in the derived categories of some surfaces of general type. We also give necessary and sufficient conditions of fullness of an exceptional collection in terms of its height and of its normal Hochschild cohomology.

description: In February of 1980, Joe Kohn arrived in my dorm room at Saint Bonaventure University where I was then a freshman. For the next several months we talked about my planned bicycle trip across the United States, recounted his own ride to Brazil, and uncovered dark stories from his three years in Zaire. One night he told me of an idea he had: He planned to canoe the entire length of the Congo River alone. For the following year or so, we mapped routes and studied the dangers. He left in the late fall of 1980, but his anticipated completion in March or April passed without word. Apparently his adventure ended tragically. While I admitted this probably true, lack of evidence forced me to investigate further. That is when my adventure began; I decided to search for Joe.

The journey I undertake is more than a search for a friend; it is a psychological search for the energy and excitement that I lost when Joe disappeared. Throughout the narrative, my search becomes one not so much of an attempt to find a body, but an attempt to find a soul, most in particular my own. The excitement, exuberance, and energy established in planning the trip is juxtaposed with the sense of hopelessness and loss of my wandering through south-central Zaire, drained of life, of hope. I search for a time that no longer existed, and my journey an attempt to return to the ideal Joe and I established in our minds. The adventure of canoeing the Congo River alone is not the heart of this narrative. It is merely a motivating factor for the story that takes place in Fly.

Yes, Joseph Kohn spent a year planning a suicidal trip that no one had ever attempted. But why would Joe attempt such a trip? Why would Joe and I ever believe it possible after all the information we unearthed during the year prior to the journey? And perhaps most importantly, why would I risk my own life to search for someone l already knew had to be dead?

description: In this paper an intrinsically non-Abelian black hole solution for the SU(2) Einstein-Yang-Mills theory in four dimensions is constructed. The gauge field of this solution has the form of a meron whereas the metric is the one of a Reissner-Nordström black hole in which, however, the coefficient of the $1/r^2$ term is not an integration constant. Even if the stress-energy tensor of the Yang-Mills field is spherically symmetric, the field strength of the Yang-Mills field itself is not. A remarkable consequence of this fact, which allows to distinguish the present solution from essentially Abelian configurations, is the Jackiw, Rebbi, Hasenfratz, 't Hooft mechanism according to which excitations of bosonic fields moving in the background of a gauge field with this characteristic behave as Fermionic degrees of freedom.

description: We propose, and constrain with the latest observational data, three model-independent parametrizations of the cosmic deceleration parameter $q(z)$. They are well behaved and stay finite at all redshifts. We construct them by fixing the value of $q$ at high redshift, $q(z \gg 1) = 1/2$ (as demanded by cosmic structure formation), and at the far future, $q(z = -1) = -1$, and smoothly interpolating $q(z)$ between them. The fixed point at $z = -1$ is not arbitrarily chosen; it readily follows from the second law of thermodynamics. This fairly reduces the ample latitude in parameterizing $q(z)$.

description: A Baker-Nunn Camera (BNC), originally installed at the Real Instituto y Observatorio de la Armada (ROA) in 1958, was refurbished and robotized. The new facility, called Telescope Fabra ROA Montsec (TFRM), was installed at the Observatori Astronòmic del Montsec (OAdM). The process of refurbishment is described in detail. Most of the steps of the refurbishment project were accomplished by purchasing commercial components, which involve little posterior engineering assembling work. The TFRM is a 0.5m aperture f/0.96 optically modified BNC, which offers a unique combination of instrumental specifications: fully robotic and remote operation, wide-field of view (4.4 deg x 4.4 deg), moderate limiting magnitude (V~19.5mag), ability of tracking at arbitrary right ascension and declination rates, as well as opening and closing CCD shutter at will during an exposure. Nearly all kind of image survey programs can benefit from those specifications. Apart from other less time consuming programs, since the beginning of science TFRM operations we have been conducting two specific and distinct surveys: super-Earths transiting around M-type dwarfs stars, and geostationary debris in the context of Space Situational Awareness / Space Surveillance and Tracking (SSA/SST) programs. Preliminary results for both cases will be shown.

description: The ethnobotanical record resulting from interactions between the Meru people and their wild plants shows a high reliance on medicinal and non-medicinal uses of these plants. In this part of Africa, wild plants are increasingly being used for medicine, food, material, social purposes, construction, fuel, environmental beauty, and wind and dust breaks. In the fight against diseases and ailments, medicine made from wild plants is beginning to compete with conventional medicines. The availability of numerous plant species growing in the area, with which humans have interacted for centuries, highlights the dependence. Indeed, the favourable climate for equatorial forests, where temperatures favour the development of numerous plant species, contributes to this region's status as a pharmacy in the making. A total of 567 plant specimens collected from three districts of the greater Meru area have been reported to be used to cure a variety of diseases as well as to meet other non-medicinal needs such as fruit, fuel, and materials. Data collected through structured interviews from respondents in the region reveal significant factors that play major roles in the lives of the people thus influencing their social and cultural behaviour. It is concluded that the use of medicinal plants in Meru as a complement to primary health care is observed and recorded among the people. The great knowledge of the people relating to useful plants and their medical properties was reported to stretch back in time to several generations.

While his ideals appeared to be utopian to many of his contemporaries, his activism and vision foreshadowed the potential (for good and evil) of the World Wide Web. This paper discusses the role that KO professionals could play in enhancing the positive social impact of the web of knowledge, and how our roles are shifting from the more passive role of descriptive cataloguers, to proactive designers of positive and productive knowledge environments.

description: We describe the Fortran code CPsuperH2.3, which incorporates the following updates compared with its predecessor CPsuperH2.0. It implements improved calculations of the Higgs-boson masses and mixing including stau contributions and finite threshold effects on the tau-lepton Yukawa coupling. It incorporates the LEP limits on the processes e^+ e^- to H_i Z, H_i H_j and the CMS limits on H_i to tau^+ tau^- obtained from 4.6/fb of data at a centre-of-mass energy of 7 TeV. It also includes the decay mode H_i to Z gamma and the Schiff-moment contributions to the electric dipole moments of Mercury and Radium225, with several calculational options for the case of Mercury. These additions make CPsuperH2.3 a suitable tool for analyzing possible CP-violating effects in the MSSM in the era of the LHC and a new generation of EDM experiments

The substitution of the torsion solutions back to our action gives the original Brans-Dicke action with $Φ$-dependent Brans-Dicke parameter $ω(Φ)$. The evolution of $ω(Φ)$ during the inflation is studied and it is found that $ω$ approaches to infinity at the end of inflation. This may solve the $ω$-problem in the extended inflation model.

description: Dans une perspective d’asymétrie informationnelle, ce papier analyse l’investissement et la pression fiscale en RD Congo. De ce fait, sur base d’un rapprochement macroéconomique et microéconomique les résultats d’analyse ont été comparés. Par l’approche macroéconomique, les recours aux séries temporelles (entre 2002 et 2023) et au modèle ADL (Autoregressive Distributed Lag) a conduit aux résultats tels que la pression fiscale et la qualité de la réglementation influencent négativement les investissements en RD Congo. S’agissant de l’attractivité des investissements, elle est positivement influencée par les dépenses courantes de l’Etat.

Par contre, sur base d’une approche microéconomique d’évaluation du climat fiscal en ville de Beni, les enquêtes révèlent que les recouvreurs fiscaux poursuivent assez souvent les objectifs opposés à leurs missions nourrissant ainsi une asymétrie informationnelle à l’égard du principal entendu comme pouvoir public.

description: We have investigated the electronic structure of CaCu3Ru4O12 and LaCu3Ru4O12 using soft x-ray photoelectron and absorption spectroscopy together with band structure and cluster configuration interaction calculations. We found the Cu to be in a robust divalent ionic state while the Ru is more itinerant in character and stabilizes the metallic state. Substitution of Ca by La predominantly affects the Ru states. We observed strong correlation effects in the Cu 3d states affecting the valence band line shape considerably. Using resonant photoelectron spectroscopy at the Cu L3 edge we were able to unveil the position of the Zhang-Rice singlet states in the one-electron removal spectrum of the Cu with respect to the Ru-derived metallic bands in the vicinity of the chemical potential.

description: This thesis studies the value, the possibilities of use, the conditions for the development and integration of experiential activities in the work of catechizing children in the context of ecclesiastical camp programs. Initially, the concept of catechism and its correlation with the developmental characteristics of childhood is approached, while then the framework of organization, structure and operation of ecclesiastical camps is developed, accompanied by the presentation of corresponding representative structures of Holy Metropolises of the Church of Greece. The theoretical part of the work is completed with the conceptualization and recording of the theories of experiential learning, the recording of the forms, conditions, teaching principles and possibilities of the experiential activities in an ecclesiastical camp environment. The second part of the paper presents the implementation of the camping program "Traveling with the Apostle Paul: Save the Apostle Paul!", the planning conditions and the stages of its implementation in the context of the camping action of the ecclesiastical camps of the Holy Metropolis of Nea Krini and Kalamaria. The paper concludes with the evaluation and reflection of the program by the researcher – author himself and is supplemented by proposals for further research and development of the topic.

description: We construct a Weyl-invariant extension of topologically massive gravity which, remarkably, turns out to include topologically massive electrodynamics, with a Proca mass term, conformally coupled to a scalar field. The action has no dimensionful parameters, therefore, the masses are generated via symmetry breaking either radiatively in flat backgrounds or spontaneously in constant curvature backgrounds. The broken phase of the theory, generically, has a single massive spin-2 and a massive spin-1 excitation. Chiral gravity in asymptotically anti-de Sitter spacetimes does not arise as a low energy theory, while chiral gravity in de Sitter spacetime is not ruled out.

Probing global aspects of a geometry by the self-force on a charge; cylindical thin-shell wormholes

description: We obtain the self-interaction for a point charge in the space-time of a cylindrical thin-shell wormhole connecting two identical locally flat geometries with a constant deficit angle. Although this wormhole geometry is locally indistinguishable from a cosmic string background, the corresponding self-forces are different even at the qualitative level. In fact in the cosmic string geometry the force is always repulsive while for the wormhole background we find that the force may point outwards or towards the wormhole throat depending on the parameters of the configuration. These results suggest that the study of the electromagnetic fields of charged particles is a useful tool for testing the global properties of a given background.

Measurement of the Ultrafast Temporal Response of a Plasmonic Antenna

description: We report a measurement on the temporal response of a plasmonic antenna at the femtosecond time scale. The antenna consists of a square array of nanometer-size gold rods. We find that the far-field dispersion of light reflected from the plasmonic antenna is less than that of a 1.2 mm thick glass slide. Assuming a simple oscillating dipole model this implies that the near-field of the antenna may be used as an electron switch that responds faster than 20 fs. Alternatively, ultrafast electron diffraction may be used to investigate the near-field dynamics of the plasmonic antenna.

Efficiency of the general quantum-mechanical Carnot engine

description: A quantum-mechanical analog of the Carnot engine reversibly working at vanishing temperature, shortly termed the quantum-mechanical Carnot engine, is discussed. A general formula for the efficiency of such an engine with an arbitrary confining potential is presented. Its expression is purely given in terms of the structure of the energy spectrum. Dependency of the efficiency on the form of a potential as an analog of the working material in thermodynamics implies nonuniversality of the engine. This may be due to the absence of the second-law-like principle in pure-state quantum mechanics.

Accelerating pulsar timing data analysis

description: The analysis of pulsar timing data, especially in pulsar timing array (PTA) projects, has encountered practical difficulties: evaluating the likelihood and/or correlation-based statistics can become prohibitively computationally expensive for large datasets. In situations where a stochastic signal of interest has a power spectral density that dominates the noise in a limited bandwidth of the total frequency domain (e.g. the isotropic background of gravitational waves), a linear transformation exists that transforms the timing residuals to a basis in which virtually all the information about the stochastic signal of interest is contained in a small fraction of basis vectors. By only considering such a small subset of these "generalised residuals", the dimensionality of the data analysis problem is greatly reduced, which can cause a large speedup in the evaluation of the likelihood: the ABC-method (Acceleration By Compression). The compression fidelity, calculable with crude estimates of the signal and noise, can be used to determine how far a dataset can be compressed without significant loss of information. Both direct tests on the likelihood, and Bayesian analysis of mock data, show that the signal can be recovered as well as with an analysis of uncompressed data. In the analysis of IPTA Mock Data Challenge datasets, speedups of a factor of three orders of magnitude are demonstrated. For realistic PTA datasets the acceleration may become greater than six orders of magnitude due to the low signal to noise ratio.
