description: We present numerical simulations of the electron-positron plasma creation process in a simple neutron star magnetosphere. We have developed a set of cascade `kernels', which represent the endpoint of the pair cascades resulting from monoenergetic photon seeds. We explore two popular models by convolving these kernels with the seed photon distributions produced by curvature radiation and by inverse Compton scattering. We find that the pair plasma in either case is well-described in its rest frame by a relativistic Maxwellian distribution with temperature near mc^2/k_B. We present cascade multiplicities and efficiencies for a range of seed particle energies and stellar magnetic fields. We find that the efficiencies and multiplicities of pair creation are often lower than has been assumed in previous work.

description: The discovery that spin-orbit coupling can generate a new state of matter in the form of quantum spin-Hall (QSH) insulators has brought topology to the forefront of condensed matter physics. While QSH states from spin-orbit coupling can be fully understood in terms of band theory, fascinating many-body effects are expected if the state instead results from interaction-generated symmetry breaking. In particular, topological defects of the corresponding order parameter provide a route to exotic quantum phase transitions. Here, we introduce a model in which the condensation of skyrmion defects in an interaction-generated QSH insulator produces a superconducting (SC) phase. Because vortex excitations of the latter carry a spin-$1/2$ degree of freedom numbers, the SC order may be understood as emerging from a gapless spin liquid normal state. The QSH-SC transition is an example of a deconfined quantum critical point (DQCP), for which we provide an improved model with only a single length scale that is accessible to large-scale quantum Monte Carlo simulations.

description: We present our results on numerical study of evolution of nonlinear perturbations inside spherically symmetric black holes in the SU(2) Einstein-Yang-Mills (EYM) theory. Recent developments demonstrate a new type of the behavior of the metric for EYM black hole interiors; the generic metric exhibits an infinitely oscillating approach to the singularity, which is a spacelike but not of the mixmaster type. The evolution of various types of spherically symmetric perturbations, propagating from the internal vicinity of the external horizon towards the singularity is investigated in a self-consistent way using an adaptive numerical algorithm. The obtained results give a strong numerical evidence in favor of nonlinear stability of the generic EYM black hole interiors. Alternatively, the EYM black hole interiors of S(chwarzschild)-type, which form only a zero measure subset in the space of all internal solutions are found to be unstable and transform to the generic type as perturbations are developed.

description: We work on a spacetime manifold foliated by timelike leaves. In this setting, we explore the solution of the second-class constraints arising during the canonical analysis of the Holst action with a cosmological constant. The solution is given in a manifestly Lorentz-covariant fashion, and the resulting canonical formulation is expressed using several sets of real variables that are related to one another by canonical transformations. By applying a gauge fixing to this formulation, we obtain a description of gravity as an $SU(1,1)$ gauge theory that resembles the Ashtekar-Barbero formulation.

Multistability and nonsmooth bifurcations in the quasiperiodically forced circle map

description: It is well-known that the dynamics of the Arnold circle map is phase-locked in regions of the parameter space called Arnold tongues. If the map is invertible, the only possible dynamics is either quasiperiodic motion, or phase-locked behavior with a unique attracting periodic orbit. Under the influence of quasiperiodic forcing the dynamics of the map changes dramatically. Inside the Arnold tongues open regions of multistability exist, and the parameter dependency of the dynamics becomes rather complex. This paper discusses the bifurcation structure inside the Arnold tongue with zero rotation number and includes a study of nonsmooth bifurcations that happen for large nonlinearity in the region with strange nonchaotic attractors.

description: We critically discuss relaxation experiments in magnetic systems that can be characterized in terms of an energy barrier distribution, showing that proper normalization of the relaxation data is needed whenever curves corresponding to different temperatures are to be compared. We show how these normalization factors can be obtained from experimental data by using the $T \ln(t/τ_0)$ scaling method without making any assumptions about the nature of the energy barrier distribution. The validity of the procedure is tested using a ferrofluid of Fe_3O_4 particles.

description: Recent innovations in Information and Communication Technologies (ICT) provide new opportunities and challenges for integration of distributed energy resources (DERs) into the energy supply system as active market players. By increasing integration of DERs, novel market platform should be designed for these new market players. The designed electricity market should maximize market surplus for consumers and suppliers and provide correct incentives for them to join the market and follow market rules. In this paper, a feeder-based market is proposed for local energy trading among prosumers and consumers in the distribution system. In this market, market players are allowed to share energy with other players in the local market and with neighborhood areas. A Two-StepMarket Clearing (2SMC) mechanism is proposed for market clearing, in which in the first step, each local market is cleared independently to determine the market clearing price and in the second step, players can trade energy with neighborhood areas. In comparison to a centralized market, the proposed method is scalable and reduces computation overheads, because instead of clearing market for a large number of players, the market is cleared for a fewer number of players. Also, by applying distributed method and Lagrangian multipliers for market clearing, there is no need for a central computation centre and private information of market players. Case studies demonstrate the efficiency and effectiveness of the proposed market clearing method in increasing social welfare and reducing computation time.

A computable multipartite multimode Gaussian correlation measure and the monogamy relation for continuous-variable systems

Publisher: name: arXiv
Year: 2020

subject: FOS: Physical sciences

description: In this paper, a computable multipartite multimode Gaussian quantum correlation measure ${\mathcal M}^{(k)}$ is proposed for any $k$-partite continuous-variable (CV) systems with $k\geq 2$. ${\mathcal M}^{(k)}$ depends only on the covariance matrix of CV states, is invariant under any permutation of subsystems, is a quantification without ancilla problem, nonincreasing under $k$-partite local Gaussian channels (particularly, invariant under $k$-partite local Gaussian unitary operations), vanishes on $k$-partite product states. For a $k$-partite Gaussian state $ρ$, ${\mathcal M}^{(k)}(ρ)=0$ if and only if $ρ$ is a $k$-partite product state. Thus, for the bipartite case, ${\mathcal M}={\mathcal M}^{(2)}$ is an accessible replacement of the Gaussian quantum discord and Gaussian geometric discord. Moreover, ${\mathcal M}^{(k)}$ satisfies the unification condition, hierarchy condition that a multipartite quantum correlation measure should obey. ${\mathcal M}^{(k)}$ is not bipartite like monogamous, but, ${\mathcal M}^{(k)}$ is complete monogamous and tight complete monogamous.

On Killing vector fields and Newman-Penrose constants

Publisher: name: arXiv
Year: 1999
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: Asymptotically flat spacetimes with one Killing vector field are considered. The Killing equations are solved asymptotically using polyhomogeneous expansions (i.e. series in powers of 1/r an ln r), and solved order by order. The solution to the leading terms of these expansions yield the asymptotic form of the Killing vector field. The possible classes of Killing fields are discussed by analysing their orbits on null infinity. The integrability conditions of the Killing equations are used to obtain constraints on the components of the Weyl tensor (Ψ_0, Ψ_1, Ψ_2) and on the shear (σ). The behaviour of the solutions to the constraint equations is studied. It is shown that for Killing fields that are non-supertranslational the characteristics of the constraint equations are the orbits of the restriction of the Killing field to null infinity. As an application, boost-rotation symmetric spacetimes are considered. The constraints on Ψ_0 are used to study the behaviour of the coefficients that give rise to the Newman-Penrose constants, if the spacetime is non-polyhomogeneous, or the logarithmic Newman-Penrose constants if the spacetime is polyhomogeneous.

description: Despite their cosmological utility, the progenitors of Type Ia supernovae (SNe Ia) are still unknown, with many efforts focused on whether accretion from a nondegenerate companion can grow a carbon-oxygen white dwarf to near the Chandrasekhar mass. The association of SNe Ia resembling SN 1991T ("91T-like") with circumstellar interaction may be evidence for this "single-degenerate" channel. However, the observed circumstellar medium (CSM) in these interacting systems is unlike a stellar wind -- of particular interest, it is sometimes detached from the stellar surface, residing at $\sim 10^{16}~{\rm cm}$. A Hubble Space Telescope (HST) program to discover detached CSM around 91T-like SNe Ia successfully discovered interaction nearly two years after explosion in SN 2015cp (Graham et al., 2018). In this work, we present radio and X-ray follow-up observations of SN 2015cp and analyze them in the framework of Harris, Nugent, & Kasen (2016) to limit the properties of a constant-density CSM shell in this system. Assuming the HST detection was shortly after the shock crossed the CSM, we constrain the total CSM mass in this system to be $< 0.5~{\rm M_\odot}$. This limit is comparable to the CSM mass of supernova PTF11kx, but does not rule out lower masses predicted for recurrent novae. From lessons learned modeling PTF11kx and SN 2015cp, we suggest a strategy for future observations of these events to increase the sample of known interacting SNe Ia.

description: Talk given at Complutense University on February 15.
Abstract: The cosmic evolution of the Universe is largely affected by the presence of Dark Matter which is so dominant that it makes up to 80% of the Universe's matter content. Dark Matter particle candidates are naturally contained in many Standard Model extensions. In addition, neutrino masses can be explained only by theories beyond the Standard Model. In this talk, I will present some models that aim to relate dark matter particle candidates and neutrino mass mechanism in the context of spontaneously broken lepton number.

description:

Between 1807 and 1856, the Royal Academy of Art in Venice played a particularly active role in the cultural life of the city. Prominent figures such as Pietro Edwards, Leopoldo Cicognara and Pietro Estense Selvatico, deeply committed to the transmission of the memory of the great Venetian masters, dedicated themselves to collect many venetian masterpieces not only to preserve them from alienation and destruction but even to increase the Accademia Gallery. The main aim of this article is to discover how and at what extent the paintings of the Venetian masters that had become part of the gallery in the first decades of the XIX century, had been copied by students, academics and contemporary painters to satisfy the ambitious expectations of famous collectors and publishers.

Classical Novae as Super-Eddington Objects

description: Several of the inconsistencies plaguing the field of novae are resolved once we consider novae to be steady state super-Eddington objects. In particular, we show that the super-Eddington shell burning state is a natural consequence of the equations of stellar structure, and that the predicted mass loss in the super-Eddington state agrees with nova observations. We also find that the transition phase of novae can be naturally explained as "stagnating" winds.

description: This essay documents the development of Dactylorhiza majalis near Braunschweig- Wenden in Lower Saxony, Germany from 1989 to 2019. Whereas one small population, lacking cultivation measures, has expired due to natural succession, the second population has significantly increased within the period of observation. This vital population is split up in two parts, which have developed differently. The reason for this totally different development is to be seen most probably in the varying water balance in the ground below.

description: A primary aim of the Nuclear Spectroscopic Telescope Array (NuSTAR) mission is to find and characterize heavily obscured Active Galactic Nuclei (AGNs). Based on mid-infrared photometry from the Wide-Field Infrared Survey Explorer (WISE) and optical photometry from the Sloan Digital Sky Surveys, we have selected a large population of luminous obscured AGN (i.e., obscured quasars). Here we report NuSTAR observations of four WISE-selected heavily obscured quasars for which we have optical spectroscopy from the Southern African Large Telescope and W. M. Keck Observatory. Optical diagnostics confirm that all four targets are AGNs. With NuSTAR hard X-ray observations, three of the four objects are undetected, while the fourth has a marginal detection. We confirm that these objects have observed hard X-ray (10-40 keV) luminosities at or below ~ 10^43 erg s^-1. We compare X-ray and IR luminosities to obtain estimates of the hydrogen column densities (N_H) based on the suppression of the hard X-ray emission. We estimate N_H of these quasars to be at or larger than 10^25 cm^-2, confirming that WISE and optical selection can identify very heavily obscured quasars that may be missed in X-ray surveys, and do not contribute significantly to the cosmic X-ray background. From the optical Balmer decrements, we found that our three extreme obscured targets lie in highly reddened host environments. This galactic extinction is not adequate to explain the more obscured AGN, but it may imply a different scale of obscuration in the galaxy.

description: Visual search of relevant targets in the environment is a crucial robot skill. We propose a preliminary framework for the execution monitor of a robot task, taking care of the robot attitude to visually searching the environment for targets involved in the task. Visual search is also relevant to recover from a failure. The framework exploits deep reinforcement learning to acquire a "common sense" scene structure and it takes advantage of a deep convolutional network to detect objects and relevant relations holding between them. The framework builds on these methods to introduce a vision-based execution monitoring, which uses classical planning as a backbone for task execution. Experiments show that with the proposed vision-based execution monitor the robot can complete simple tasks and can recover from failures in autonomy.

Magnetoresistance of composite fermions at ν=1/2

description: We have studied temperature dependence of both diagonal and Hall resistivity in the vicinity of $ν=1/2$. Magnetoresistance was found to be positive and almost independent of temperature: temperature enters resistivity as a logarithmic correction. At the same time, no measurable corrections to the Hall resistivity has been found. Neither of these results can be explained within the mean-field theory of composite fermions by an analogy with conventional low-field interaction theory. There is an indication that interactions of composite fermions with fluctuations of the gauge field may reconcile the theory and experiment.

description:

The present article reconstructs the nineteenth-century exhibition history of Ritrovamento del corpo di S. Marco by Tintoretto, through the analysis of the museum policy interventions on the painting: from the arrival to Brera in 1811, to the elaboration that led to its transfer to the Church of Saint Mark in 1847, up to the reasons for its recovery, which took place only in 1886. The Reconstruction will take into account the developments of the artist’s critical fortune in Italy, but will also be read in relation to the evolution of the public function assigned to Brera collection, which became independent from the Academy of Fine Arts in 1882.

Enhanced second harmonic generation and photon drag effect in a doped graphene placed on a two-dimensional diffraction grating
Creators: name: Ochiai, Tetsuyuki
Publisher: name: arXiv
Year: 2018
Subjects: subject: Optics (physics.optics)
subject: FOS: Physical sciences

description: We theoretically investigate the second harmonic generation and photon drag effect induced by an incident plane wave to a doped graphene placed on a two-dimensional diffraction grating. The relevant nonlinear conductivity of the graphene is obtained by a semi-classical treatment with a phenomenological relaxation. The grating acts not only as a plasmon coupler but also as a dispersion modulator of the graphene plasmon. As a result, the second harmonic generation is strongly enhanced by exciting the graphene plasmon polariton of the first- and/or second-harmonic frequencies. The photon drag effect is also strongly enhanced by the excitation of the plasmon at the first-harmonic frequency. The direct current induced by the photon drag effect flows both forward and backward directions to the incident light, depending on the modulated plasmon mode concerned.

Tommaso Riario Sforza, Filippo Agricola, Giovanni Regis e una lettera anonima per il restauro del Ratto d’Europa di Paolo Veronese della Pinacoteca Capitolina nel 1844

description:

The present paper takes the cue from an anonymous letter sent in 1844 to the camerlengo Tommaso Riario Sforza to denounce the poor conservative conditions in which Veronese’s Rape of Europe, in the Pinacoteca Capitolina in Rome, was placed. Considered one of the gems of the Roman collections, as the contemporary sources attest, especially due to the scarcity of works by Venetian masters in Rome, the large canvas was important above all as a model for young artists to exercise on colouring. Following this complaint, the painting will be taken over by the under-inspector Filippo Agricola, who will make the design for a new frame and will entrust the restoration to Giovanni Regis.

description: The semi-classical collapse, including lowest order back-reaction, of a thin shell of self-gravitating quantized matter is illustrated. The conditions for which self-gravitating matter forms a thin shell are first discussed and an effective Lagrangian for such matter is obtained. The matter-gravity system is then quantized, the semi-classical limit for gravitation is taken and the method of adiabatic invariants is applied to the resulting time dependent matter Hamiltonian. The governing equations are integrated numerically, for suitable initial conditions, in order to illustrate the effect of back-reaction, due to the creation of matter, in slowing down the collapse near the horizon.

description: Thinking is a human feature which differentiates Empathetic Minds from the rest of Sympathetic Minds. This books focuses on a type of thinking that we all deserve that can help in creating a legacy and change the world. The work of the book comes from the Dr. Buheji’s accumulated experience which are presented through stages of reflection and discernment based on two principles that differentiate his approach namely knowledge and imagination. Dr. Buheji sees the mind as a bird, it must be free. It is like the bird whom cannot fly and perform if it is in a cage. The further the mind is a way from Muslim fanaticism, nets, traps of arrogance and overconfidence the better. The author warn about self and personal interests that obscure the vision for the theme of contribution in life, and making the difference in it. The book reflects the expert studies, experiences supported with and examples of those whom was and still of inspiration for many because of their Empathetic Thinking. Those inspiring thinkers who changed the course of civilization and the progress of many Nations, managed to set for us a type of path that can be called "thinking worthy of life." The book provides school of thought very essential for the Arab and developing world. This type of thinking requires practices that are linked to exploring and owning and managing knowledge. "Thinking worthy of life" is a self-discovery search for excellence, exercise creativity and eager to create legacy with quest for creating a difference in our nations.

Quintessence, the Gravitational Constant, and Gravity

description: Dynamical vacuum energy or quintessence, a slowly varying and spatially inhomogeneous component of the energy density with negative pressure, is currently consistent with the observational data. One potential difficulty with the idea of quintessence is that couplings to ordinary matter should be strongly suppressed so as not to lead to observable time variations of the constants of nature. We further explore the possibility of an explicit coupling between the quintessence field and the curvature. Since such a scalar field gives rise to another gravity force of long range ($\simg H^{-1}_0$), the solar system experiments put a constraint on the non-minimal coupling: $|ξ| \siml 10^{-2}$.

L’arte veneta nei disegni di Crowe e Cavalcaselle conservati presso la National Art Library di Londra
Creators: name: Fraticelli, Valentina
Publisher: name: Università Ca’ Foscari Venezia, Italia
Year: 2019

description:

The collaboration between Joseph Archer Crowe and Giovanni Battista Cavalcaselle led to the publication of numerous printed works, to achieve which the two scholars developed a method of study and investigation of absolutely innovative works of art. Their private archives, preserved at the National Art Library of London and the Biblioteca Marciana of Venice, represent the most complete and precious collection of reproductions of works of Italian art from the Middle Ages to the seventeenth century. In the funds, several drawings of works of art of the Veneto – reflecting also a personal interest as well as scientific rigour – and the artistic history of the region from the Middle Ages to the seventeenth century can be traced, with an interesting deepening on the figure of Titian.

description: Transformation Management is not just a Change Management, it is a fate for nations that need to pick up the spirit of Agility, persistence and Social Learning to meet instable trends. The Author set his techniques for transformation by using life and practical examples from what he developed as Transformational Labs© which was tested in different societies and organisations. The book focus on the design of transformational strategies and practices that would lead to gradual maturity for managing resistance towards any transformation. The psychological and risk factors are discussed to reflect the importance of Radical Transformation for developing countries and the Arab World Specifically. The book concludes with recommendations for handling transformation in unstable future and in a knowledge economy.
Primi materiali sulla presenza della fotografia alla Scuola Grande di San Rocco in Venezia
Creators: name: Filippin, Sara
Publisher: name: Università Ca’ Foscari Venezia, Italia
Year: 2019

description:

Based on the examination of the documents present in the Historical Archive of the Scuola Grande di San Rocco, in Venice, this essay proposes the first results of a research on the use of photography in that Institution in the period between the 1880s and the 1930s. The relationship with some important photographers is reconstructed, above all with the Roman photographer Domenico Anderson, to whom the exclusive right for the reproduction of the works of art of the Scuola was granted in 1896. The analysis of the sales of photographs carried out there makes it possible to verify the subjects that visitors appreciated most, especially with regard to Tintoretto’s paintings.

description: The nature and role of the binary companion of carbon-oxygen white dwarf stars that explode as Type Ia supernovae (SNe Ia) are not yet fully understood. Past detections of circumstellar material (CSM) that contain hydrogen for a small number of SN Ia progenitor systems suggest that at least some have a nondegenerate companion. In order to constrain the prevalence, location, and quantity of CSM in SN Ia systems, we performed a near-ultraviolet (NUV) survey with the Hubble Space Telescope (HST) to look for the high-energy signature of SN Ia ejecta interacting with CSM. Our survey revealed that SN 2015cp, a SN 1991T-like overluminous SN Ia, was experiencing late-onset interaction between its ejecta and surrounding CSM at $664$ days after its light-curve peak. We present ground- and space-based follow-up observations of SN 2015cp that reveal optical emission lines of H and Ca, typical signatures of ejecta-CSM interaction. We show how SN 2015cp was likely similar to the well-studied SN Ia-CSM event PTF11kx, making it the second case in which an unambiguously classified SN Ia was observed to interact with a distant shell of CSM that contains hydrogen ($R_{\rm CSM} \gtrsim 10^{16}\ {\rm cm}$). The remainder of our HST NUV images of SNe Ia were nondetections that we use to constrain the occurrence rate of observable late-onset CSM interaction. We apply theoretical models for the emission from ejecta-CSM interaction to our NUV nondetections, and place upper limits on the mass and radial extent of CSM in SN Ia progenitor systems.

description: We consider a massive selfgravitating shell as a model for collapsing body and a null selfgravitating shell as a model for quanta of Hawking radiation. It is show that the mass-energy spectra for the body and the radiation do not match. The way out of this difficulty is to consider not only out-going radiation but also the ingoing one. It means that the structure of black hole is changing during its evaporation resulting in the Bekenstein-Mukhanov spectrum for large masses.
