Black Hole Probes of Automorphic Space

Subjects: subject: High Energy Physics - Theory (hep-th)

description: Over the past few years the arithmetic Langlands program has proven useful in addressing physical problems. In this paper it is shown how Langlands' reciprocity conjecture for automorphic forms, in combination with a representation theoretic notion of motives, suggests a framework in which the entropy of automorphic black holes can be viewed as a probe of spacetime that is sensitive to the geometry of the extra dimensions predicted by string theory. If it were possible to produce black holes with automorphic entropy in the laboratory their evaporation would provide us with information about the precise shape of the compact geometry.

description: We present a novel implementation of conditional Long Short-Term Memory Recurrent Neural Networks that successfully predict the spectral evolution of a pulse in nonlinear periodically-poled waveguides. The developed networks offer large flexibility by allowing the propagation of optical pulses with ranges of energies and temporal widths in waveguides with different poling periods. The results show very high agreement with the traditional numerical models. Moreover, we are able to use a single network to calculate both the real and imaginary parts of the pulse complex envelope, allowing for successfully retrieving the pulse temporal and spectral evolution using the same network.

description: The Dirichlet Laplacian between two parallel hypersurfaces in Euclidean spaces of any dimension in the presence of a magnetic field is considered in the limit when the distance between the hypersurfaces tends to zero. We show that the Laplacian converges in a norm-resolvent sense to a Schroedinger operator on the limiting hypersurface whose electromagnetic potential is expressed in terms of principal curvatures and the projection of the ambient vector potential to the hypersurface. As an application, we obtain an effective approximation of bound-state energies and eigenfunctions in thin quantum layers.

Year: 2016

description: The Kentucky Transportation Center, with the assistance of the University of Kentucky’s Survey Research Center, administered a telephone survey to 1,221 licensed drivers throughout the state to gauge their opinion of the Kentucky Transportation Cabinet’s (KYTC) maintenance activities. Survey respondents were distributed throughout KYTC’s 12 highway districts. The survey focused on five areas of highway maintenance: roadside features, pavement surfaces, shoulders, drainage and signs/markings. Respondents indicated they were most satisfied with the current maintenance of signs, guardrail, and striping. Pavement surfaces and potholes, and shoulders and roadway drainage, received the lowest rankings — given that the driving public is very attuned to the smoothness of roadways and readily detects problems, this result was expected. The survey also asked respondents about to specify what level of maintenance they desired for each category. Results for these questions were practically identical across the entire state, with respondents expressing a desire that roads and road features be maintained in very good to excellent condition. There were no differences between items relating to pavement surfaces or safety items. Researchers compared the 2016 survey results to the findings of a 2010 survey. There were few differences between the surveys, and in general the results mirrored each other very closely. New questions added in 2016 asked drivers about their primary sources of travel information. Drivers reported using smartphone apps to obtain travel directions and road conditions, but that traditional media outlets (e.g., television, radio) remain critical sources of information.

description: To explain several properties of finite nuclei, infinite matter, and neutron stars in a unified way within the relativistic mean field models, it is important to extend them either with higher order couplings or with density-dependent couplings. These extensions are known to have strong impact in the high-density regime. Here we explore their role on the equation of state at densities lower than the saturation density of finite nuclei which govern the phase transitions associated with pasta structures in the crust of neutron stars.

Holographic Entanglement Entropy for Excited States in Two Dimensional CFT

Publisher: name: arXiv
Year: 2013
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We use holographic methods to study the entanglement entropy for excited states in a two dimensional conformal field theory. The entangling area is a single interval and the excitations are produced by in and out vertex operators with given scaling dimensions. On the gravity side we provide the excitations by turning on a scalar field with an appropriate mass. The calculation amounts to using the gravitational background, with a singular boundary, to find the one point function of the vertex operators. The singular boundary is taken care of by introducing a nontrivial UV regulator surface to calculate gravitational partition functions. By means of holographic methods we reproduce the field theory results for primary excitations.

description: We propose the use of nanostructured photonic nanocavities made of second-order nonlinear materials as prospective passive devices to generate strongly sub-Poissonian light via single-photon blockade of an input coherent field. The simplest scheme is based on the requirement that the nanocavity be doubly resonant, i.e. possess cavity modes with good spatial overlap at both the fundamental and second-harmonic frequencies. We discuss feasibility of this scheme with state-of-the art nanofabrication technology, and the possibility to use it as a passive single-photon source on-demand.

description: Главную роль в обеспечении электроэнергией потребителей на автомобилях и тракторах выполняет генератор, выход из строя которого может привести к последствиям разной тяжести. В связи с этим является актуальной проблема диагностирования текущего состояния автотракторных генераторов, особенно для сельхозпроизводителей, финансовые средства которых на приобретение новой генераторной техники и постоянного её ремонта существенно ограничены. Результаты анализа существующих методов диагностирования показали, что наиболее эффективными в плане экономичности, достоверности, оперативности и высокой информативности являются осциллографические методы. На кафедре технической эксплуатации и ремонта автомобилей Оренбургского государственного университета разработан метод экспресс-диагностирования генератора, который позволяет проводить оценку технического состояния любых синхронных вентильных генераторов без снятия с автомобиля или трактора по параметрам выходного напряжения путём сопоставления полученного значения размаха пульсации с допустимым. Рассматриваемый метод можно отнести к экспресс-методам на основании минимальной трудоёмкости (менее 3 чел.-мин.) и ограниченного числа диагностируемых параметров (среднее значение и размах пульсации выходного напряжения). В качестве основного диагностического параметра принят размах пульсации выходного напряжения как наиболее чувствительный к неисправностям генераторов. Для определения диагностических параметров авторы предлагают снимать осциллограммы на силовом выходе автотракторного генератора, предварительно отключив его от аккумуляторной батареи, что позволит исключить сглаживающее действие аккумуляторной батареи на форму осциллограмм выходного напряжения и повысит их информативность. Предложена схема выполнения экспресс-диагностирования. Проанализированы результаты диагностирования автотракторных генераторов предлагаемым методом. Доказано, что применение предложенного диагностического параметра позволяет оценить остаточный ресурс автотракторных генераторов и будет способствовать повышению эффективности эксплуатации автомобилей и тракторов за счёт снижения простоев в ремонте.

description: Features of the controllable displacement, annihilation, and transformation of macroscopic regions of a weak frozen magnetic field (FMF) have been experimentally studied in a plate of granulated ceramic YBa2Cu3O7-x under the action of the transport current flowing through it. It is shown that the displacement of regions with an FMF lower than the first critical field of the ceramic granules (Hc1g) is associated with a relatively weak pinning force of the hypervortices that is less than the maximum experimentally attainable Lorenz force. A discussion is presented of the role of the transport current that not only is one of the conditions for the appearance of the Lorenz force but also acts on the internal current structure of the local FMF, which in turn influences its mobility and magnitude. If a local field greater than Hc1g is frozen in, the experimentally produced Lorenz force is less than the pinning force of the Abrikosov vortices in the mixed state of the granules, and there is no displacement of the regions with an FMF.

description: The present-day Universe is highly magnetized, even though the first magnetic seed fields were most probably extremely weak. To explain the growth of the magnetic field strength over many orders of magnitude fast amplification processes need to operate. The most efficient mechanism known today is the small-scale dynamo, which converts turbulent kinetic energy into magnetic energy leading to an exponential growth of the magnetic field. The efficiency of the dynamo depends on the type of turbulence indicated by the slope of the turbulence spectrum v(l) \propto l^{theta}, where v(l) is the eddy velocity at a scale l. We explore turbulent spectra ranging from incompressible Kolmogorov turbulence with theta = 1/3 to highly compressible Burgers turbulence with theta = 1/2. In this work we analyze the properties of the small-scale dynamo for low magnetic Prandtl numbers Pm, which denotes the ratio of the magnetic Reynolds number, Rm, to the hydrodynamical one, Re. We solve the Kazantsev equation, which describes the evolution of the small-scale magnetic field, using the WKB approximation. In the limit of low magnetic Prandtl numbers the growth rate is proportional to Rm^{(1-theta)/(1+theta)}. We furthermore discuss the critical magnetic Reynolds number Rm_crit, which is required for small-scale dynamo action. The value of Rm_crit is roughly 100 for Kolmogorov turbulence and 2700 for Burgers. Furthermore, we discuss that Rm_crit provides a stronger constraint in the limit of low Pm than it does for large Pm. We conclude that the small-scale dynamo can operate in the regime of low magnetic Prandtl numbers, if the magnetic Reynolds number is large enough. Thus, the magnetic field amplification on small scales can take place in a broad range of physical environments and amplify week magnetic seed fields on short timescales.

description: We investigated the transverse charge densities in the nucleon in nuclear matter within the framework of the in-medium modified Skyrme model. The medium modification of the nucleon electromagnetic form factors are first discussed. The results show that the form factors in nuclear matter fall off faster than those in free space, as the momentum transfer increases. As a result, the charge radii of the nucleon become larger, as the nuclear matter density increases. The transverse charge densities in the nucleon indicate that the size of the nucleon tends to bulge out in nuclear matter. This salient feature of the swelling is more clearly observed in the neutron case. When the proton is transversely polarized, the transverse charge densities exhibit the distortion due to the effects of the magnetization.

description: To further reduce the lattice thermal conductivity of thermoelectric materials, the technique of embedding nano-inclusions into bulk matrix materials, in addition to point defect scattering via alloying, was widely applied. Differential Effective Medium (DEM) method was employed to calculate two-phase heterogeneous systems. However, in most effective medium treatment, the interface scattering of matrix phonons by embedded nanoparticle was underestimated by adopting particle's projected area as scattering cross-section. Herein, modified cross-section calculations, as well as grain sizes dispersions, are applied in DEM, with the calculations then validated by comparing with Monte-Carlo simulations and existing experimental data. Predictions of lattice thermal conductivity reduction on in-situ formed Full Heusler(FH)/Half Heusler(HH) nano/matrix system are discussed.

description: We present a scheme to construct model potentials, with parameters computed from first principles, for large-scale lattice-dynamical simulations of materials. Our method mimics the traditional solid-state approach to the investigation of vibrational spectra, i.e., we start from a suitably chosen reference configuration of the material and describe its energy as a function of arbitrary atomic distortions by means of a Taylor series. Such a form of the potential-energy surface is completely general, trivial to formulate for any compound, and physically transparent. Further, the approximations involved in our effective models are clear-cut, and the precision can be improved in a systematic and well-defined fashion. Moreover, such a simple definition allows for a straightforward determination of the parameters in the low-order terms of the series, as they are the direct result of density-functional-perturbation-theory calculations, which greatly simplifies the model construction. Here we present such a scheme, discuss a practical and versatile methodology for the calculation of the model parameters from first principles, and describe our results for two challenging cases in which the model potential is strongly anharmonic, namely, ferroic perovskite oxides PbTiO3 and SrTiO3. The choice of test materials was partly motivated by historical reasons, since our scheme can be viewed as a natural extension of (and was initially inspired by) the so-called first-principles effective Hamiltonian approach to the investigation of temperature-driven effects in ferroelectric perovskite oxides. Thus, the study of these compounds allows us to better describe the connections between the effective-Hamiltonian method and ours.

description: С учётом причинно-следственной связи факторов изменения теплового состояния генератора разработана регрессионная модель теплового состояния автотракторных генераторов в процессе эксплуатации. Показано, что тепловое состояние автотракторных генераторов определяется не только сочетанием климатических и эксплуатационных факторов, но и их техническим состоянием. В ходе производственных испытаний установлено количественное влияние температуры окружающей среды, скорости движения транспортного средства, частоты вращения ротора генератора и силы тока потребителей на температуру поверхности генератора. Разработана общая регрессионная модель, отражающая вклад вышеперечисленных факторов в тепловое состояние автотракторных генераторов.

description: We introduce Dagma-DCE, an interpretable and model-agnostic scheme for differentiable causal discovery. Current non- or over-parametric methods in differentiable causal discovery use opaque proxies of ``independence'' to justify the inclusion or exclusion of a causal relationship. We show theoretically and empirically that these proxies may be arbitrarily different than the actual causal strength. Juxtaposed to existing differentiable causal discovery algorithms, \textsc{Dagma-DCE} uses an interpretable measure of causal strength to define weighted adjacency matrices. In a number of simulated datasets, we show our method achieves state-of-the-art level performance. We additionally show that \textsc{Dagma-DCE} allows for principled thresholding and sparsity penalties by domain-experts. The code for our method is available open-source at https://github.com/DanWaxman/DAGMA-DCE, and can easily be adapted to arbitrary differentiable models.

description: В статье обосновано положение о том, что наиболее информативным диагностическим параметром, чувствительным как к возникновению неисправностей, так и к изменению ресурса работы генераторов, является величина размаха пульсации выходного напряжения. Охарактеризованы существующие методы определения оптимальной периодичности диагностирования, доказано, что они дают разброс численных значений, образующих две группы. Анализ численных значений показал, что с периодичностью 75-110 тыс. км необходимо проводить первое диагностирование, а с периодичностью 20-40 тыс. км последующие диагностирования автотракторных генераторов. Сделан вывод о том, что диагностирование автотракторных генераторов с установленной периодичностью позволит снизить простои автомобилей и тракторов в ремонте по причине выхода из строя генераторов. С использованием экспериментальных значений вероятности безотказной работы автотракторных генераторов были получены окончательные значения периодичности. Показано, что для обнаружения скрытых отказов автотракторных генераторов необходимо проводить первое диагностирование предлагаемым методом при наработке =105 тыс. км, и далее постоянно, с установленной периодичностью диагностирования =30 тыс. км. Диагностирование автотракторных генераторов с установленной периодичностью способствует повышению надёжности работы автомобильных генераторов на этапе эксплуатации, поскольку обеспечивает прогнозирование их функционирования, в том числе и отказов.

description: A whole class of two-color experiments involves intense, short Terahertz radiation pulses. A fast detector that is sensitive and able to resolve both near-infrared and Terahertz pulses at the same time is highly desirable. Here we present the first detector of this kind. The detector element is a GaAs-based field effect transistor operated at room temperature. THz detection is successfully demonstrated at frequencies up to 4.9 THz. The THz detection time constant is shorter than 30 ps, the optical time constant is 150 ps. This detector is ideally suited for precise, simultaneous resolution of optical and THz pulses and for pulse characterization of high-power THz pulses up to tens of kW peak power levels. The dynamic range of the detector was as large as 65 $\pm$ 3 dB/$\sqrt{Hz}$, enabling applications in a large variety of experiments and setups, also including table-top systems.

description: Обследовали 138 молодых нерожавших женщин, планирующих беременность, у которых в анамнезе отмечены частые рецидивы хламидийной и микоплазменной инфекций урогенитального тракта. Установили, что такой кольпоскопический признак, как помутнение содержимого закрытых желез шейки матки (наботовы кисты), говорит об инфицированности железы. Выявили, что хламидийная и микоплазменная инфекции могут длительно и бессимптомно персистировать в наботовых кистах. Разработали подход к выбору методов диагностики и лечения.

description: Comprehensive approaches to predict performance of wood products are requested by international standards, and the first attempts have been made in the frame of European research projects. However, there is still an imminent need for a methodology to implement the durability and moisture performance of wood in an engineering design method and performance classification system. The aim of this study was therefore to establish an approach to predict service life of wood above ground taking into account the combined effect of wetting ability and durability data. A comprehensive data set was obtained from laboratory durability tests and still ongoing field trials in Norway, Germany and Sweden. In addition, four different wetting ability tests were performed with the same material. Based on a dose-response concept, decay rates for specimens exposed above ground were predicted implementing various indicating factors. A model was developed and optimised taking into account the resistance of wood against soft, white and brown rot as well as relevant types of water uptake and release. Decay rates from above-ground field tests at different test sites in Norway were predicted with the model. In a second step, the model was validated using data from laboratory and field tests performed in Germany and Sweden. The model was found to be fairly reliable, and it has the advantage to get implemented into existing engineering design guidelines. The approach at hand might furthermore be used for implementing wetting ability data into performance classification as requested by European standardisation bodies.

description: We present Atacama Large Millimeter/sub-millimeter Array (ALMA) Cycle-5 observations of HBC 494, as well as calculations of the kinematic and dynamic variables which represent the object's wide-angle bipolar outflows. HBC 494 is a binary FU Orionis type object located in the Orion A molecular cloud. We take advantage of combining the ALMA main array, Atacama Compact Array (ACA), and Total Power (TP) array in order to map HBC 494's outflows and thus, estimate their kinematic parameters with higher accuracy in comparison to prior publications. We use $^{12}$CO, $^{13}$CO, C$^{18}$O and SO observations to describe the object's outflows, envelope, and disc, as well as estimate the mass, momentum, and kinetic energy of the outflows. After correcting for optical opacity near systemic velocities, we estimate a mass of $3.0\times10^{-2}$ M$_{\odot}$ for the southern outflow and $2.8\times10^{-2}$ M$_{\odot}$ for the northern outflow. We report the first detection of a secondary outflow cavity located approximately $15$" north of the central binary system, which could be a remnant of a previous large-scale accretion outburst. Furthermore, we find CO spatial features in HBC 494's outflows corresponding to position angles of $\sim35^{\circ}$ and $\sim145^{\circ}$. This suggests that HBC 494's outflows are most likely a composite of overlapping outflows from two different sources, i.e., HBC 494a and HBC 494b, the two objects in the binary system.
