description: We study scattering equations and formulas for tree amplitudes of various theories in four dimensions, in terms of spinor helicity variables and on-shell superspace for supersymmetric theories. As originally obtained in Witten's twistor string theory and other twistor-string models, the equations can take either polynomial or rational forms, and we clarify the simple relation between them. We present new, four-dimensional formulas for all tree amplitudes in the non-linear sigma model, a special Galileon theory and the maximally supersymmetric completion of the Dirac-Born-Infeld theory. Furthermore, we apply the formulas to study various double-soft theorems in these theories, including the emissions of a pair of soft photons, fermions and scalars for super-amplitudes in super-DBI theory.

description: The subject of this thesis is the development of a modeling framework for the depiction of transnational interactions taking place via common participation in multilateral institutions, focusing, in particular, on defense alliances and using tools derived from social network analysis. More specifically, hypergraphs capturing the joint participation of states in interstate alliances will be constructed and the importance of the positions held by the states included in the analyzed networks will be estimated. The structural impact of states will be identified at the micro, meso and macro level and relevant indices will be calculated via the heavy use of spectral graph theory. The main goals of the analysis are the following: Firstly, to define in a quantitative as well as a qualitative manner the social science concept of structural power and, secondly, to bring to the fore the overlooked but nonetheless crucial role of structural power for a thorough understanding of international politics. The presented theoretical and mathematical framework aspires to introduce a more comprehensive integration of the complexity science approach into the social sciences and, in particular, into the field of International Relations.

description: We demonstrate an experimental method for measuring energy-time entanglement over almost 80 nm spectral bandwidth in a single shot with a quantum bit error rate below 0.5%. Our scheme is extremely cost-effective and efficient in terms of resources as it employs only one source of entangled photons and one fixed unbalanced interferometer per phase-coded analysis basis. We show that the maximum analysis spectral bandwidth is obtained when the analysis interferometers are properly unbalanced, a strategy which can be straightforwardly applied to most of today's experiments based on energy-time and time-bin entanglement. Our scheme has therefore a great potential for boosting bit rates and reducing the resource overhead of future entanglement-based quantum key distribution systems.

description: Many explanations for the decline in real interest rates over the last 30 years point to the role
that population aging or rising income inequality plays in increasing the long-run aggregate
demand for assets. Notwithstanding the importance of such factors, the starting point of this
paper is to show that the major change driving household asset demand over this period is
instead an increased desire—for a given age and income level—to hold assets. We begin by
presenting a simple explanation for this pattern that relies on integrating retirement and intertemporal substitution motives in saving decisions. We then show how the interaction of these
two saving motives can have profound implications in terms of the shape of asset demands,
the possibility of multiple steady state real interest rates, and a potential role for monetary
policy to influence the long-run evolution of real rates. The framework highlights how an
inflationary episode followed by a strong monetary response, as we are currently witnessing,
can have long-term implications for real interest rates.
description: Bon nombre des raisons avancées pour expliquer le recul des taux d’intérêt lors des
30 dernières années soulignent le rôle joué par le vieillissement de la population ou la montée
des inégalités de revenu dans la croissance de la demande agrégée d’actifs sur le long terme.
Sans nier l’importance de ces facteurs, cette étude montre tout d’abord que le principal
changement à l’origine d’une hausse de la demande d’actifs au cours de cette période a plutôt
été le désir accru des ménages (selon leur classe d’âge et catégorie de revenu) d’acquérir des
actifs. Nous commençons par présenter une explication simple de cette tendance en nous
appuyant sur les besoins d’épargne motivés par la retraite et la substitution intertemporelle.
Nous montrons ensuite que l’interaction de ces deux motifs d’épargne peut avoir des
conséquences majeures sur la forme des différentes demandes d’actifs, sur la multiplicité des
taux d’intérêt envisageables à l’état stationnaire et sur l’influence potentielle de la politique
monétaire dans l’évolution à long terme des taux réels. Le cadre met en lumière les retombées
que peut générer à long terme sur les taux d’intérêt réels un épisode inflationniste suivi d’une
forte réaction des autorités monétaires (comparable à la situation actuelle).

description: Motivated by recent developments of BTZ black holes and interesting results of massive gravity, we investigate massive BTZ black holes in the presence of Maxwell and Born-Infeld (BI) electrodynamics. We study geometrical properties such as type of singularity and asymptotical behavior as well as thermodynamic structure of the solutions through canonical ensemble. We show that despite the existence of massive term, obtained solutions are asymptotically (a)dS and have a curvature singularity at the origin. Then, we regard varying cosmological constant and examine the Van der Waals like behavior of the solutions in extended phase space. In addition, we employ geometrical thermodynamic approaches and show that using Weinhold, Ruppeiner and Quevedo metrics leads to existence of ensemble dependency while HPEM metric yields consistent picture. For neutral solutions, it will be shown that generalization to massive gravity leads to the presence of non-zero temperature and heat capacity for vanishing horizon radius. Such behavior is not observed for linearly charged solutions while generalization to nonlinearly one recovers this property.

description: We present a preliminary study of both Single and Double Parton Scattering contributions to the inclusive 4-jet production in the kt-factorization framework at Leading Order and $E_{CM} = 7$ TeV. We compare our results to collinear results in the literature and to the ATLAS and CMS data at 8 and 7 TeV respectively. We also discuss the importance of double parton scattering for relatively soft cuts on the jet transverse momenta and find out that symmetric cuts do not quite suit well to kt-factorization predictions, because of a kinematic effect suppressing the double parton scattering contribution.

description: This paper deals with the problem of identifying and estimating dynamical parameters of continuous-time quantum open systems, in the input-output formalism. First, we characterise the space of identifiable parameters for ergodic dynamics, assuming full access to the output state for arbitrarily long times, and show that the equivalence classes of undistinguishable parameters are orbits of a Lie group acting on the space of dynamical parameters. Second, we define an information geometric structure on this space, including a principal bundle given by the action of the group, as well as a compatible connection, and a Riemannian metric based on the quantum Fisher information of the output. We compute the metric explicitly in terms of the Markov covariance of certain "fluctuation operators", and relate it to the horizontal bundle of the connection. Third, we show that the system-output and reduced output state satisfy local asymptotic normality, i.e. they can be approximated by a Gaussian model consisting of coherent states of a multimode continuos variables system constructed from the Markov covariance "data". We illustrate the result by working out the details of the information geometry of a physically relevant two-level system.

description: Scalar particles coupled to the Standard Model fields through a disformal coupling arise in different theories, such as massive gravity or brane-world models. We will review the main phenomenology associated with such particles. Distinctive disformal signatures could be measured at colliders and with astrophysical observations. The phenomenological relevance of the disformal coupling demands the introduction of a set of symmetries, which may ensure the stability of these new degrees of freedom. In such a case, they constitute natural dark matter candidates since they are generally massive and weakly coupled. We will illustrate these ideas by paying particular attention to the branon case, since these questions arise naturally in brane-world models with low tension, where they were first discussed.

Particle-in-Cell simulation of two-dimensional electron velocity shear driven instability in relativistic domain

description: We carry out Particle-in-Cell (PIC) simulations to study the instabilities associated with a 2-D sheared electron flow configuration against a neutralizing background of ions. Both weak and strong relativistic flow velocities are considered. In the weakly relativistic case, we observe the development of electromagnetic Kelvin Helmholtz instability with similar characteristics as that predicted by the electron Magnetohydrodynamic (EMHD) model. On other hand, in strong relativistic case the compressibility effects of electron fluid dominate and introduce upper hybrid electrostatic oscillations transverse to the flow which are very distinct from EMHD fluid behaviour. In the nonlinear regime, both weak and strong relativistic cases lead to turbulence with broad power law spectrum.
Plasma rotation from momentum transport by neutrals in tokamaks

Subjects: subject: Plasma Physics (physics.plasm-ph)

description: Neutral atoms can strongly influence the intrinsic rotation and radial electric field at the tokamak edge. Here, we present a framework to investigate these effects when the neutrals dominate the momentum transport. We explore the parameter space numerically, using highly flexible model geometries and a state of the art kinetic solver. We find that the most important parameters controlling the toroidal rotation and electric field are the major radius where the neutrals are localized and the plasma collisionality. This offers a means to influence the rotation and electric field by, for example, varying the radial position of the X-point to change the major radius of the neutral peak.
Quantum to Classical Transitions via Weak Measurements and Post-Selection

Publisher: name: arXiv
Year: 2016
Subjects: subject: Quantum Physics (quant-ph)
subject: FOS: Physical sciences

description: This work will incorporate a few related tools for addressing the conceptual difficulties arising from sewing together classical and quantum mechanics: deterministic operators, weak measurements and post-selection. Weak Measurement, based on a very weak von Neumann coupling, is a unique kind of quantum measurement with numerous theoretical and practical applications. In contrast to other measurement techniques, it allows to gather a small amount of information regarding the quantum system, with only a negligible probability of collapsing it. A single weak measurement yields an almost random outcome, but when performed repeatedly over a large ensemble, the averaged outcome becomes increasingly robust and accurate. Importantly, a long sequence of weak measurements can be thought of as a single projective measurement. I claim in this work that classical variables appearing in the macro-world, such as centre of mass, moment of inertia, pressure and average forces, result from a multitude of quantum weak measurements performed in the micro-world. Here again, the quantum outcomes are highly uncertain, but the law of large numbers obliges their convergence to the definite quantities we know from our everyday lives. By augmenting this description with a final boundary condition and employing the notion of "classical robustness under time-reversal" I will draw a quantitative borderline between the classical and quantum regimes. I will conclude by analyzing the role of macroscopic systems in amplifying and recording quantum outcomes.

Obtaining Atomic Matrix Elements from Vector Tune-Out Wavelengths using Atom Interferometry

Year: 2016

description: Accurate values for atomic dipole matrix elements are useful in many areas of physics, and in particular for interpreting experiments such as atomic parity violation. Obtaining accurate matrix element values is a challenge for both experiment and theory. A new technique that can be applied to this problem is tune-out spectroscopy, which is the measurement of light wavelengths where the electric polarizability of an atom has a zero. Using atom interferometry methods, tune-out wavelengths can be measured very accurately. Their values depend on the ratios of various dipole matrix elements and are thus useful for constraining theory and broadening the application of experimental values. Tune-out wavelength measurements to date have focused on zeros of the scalar polarizability, but in general the vector polarizability also contributes. We show here that combined measurements of the vector and scalar polarizabilities can provide more detailed information about the matrix element ratios, and in particular can distinguish small contributions from the atomic core and the valence tail states. These small contributions are the leading error sources in current parity violation calculations for cesium.

description: We study drag-driven instability in a protoplanetary disc consisting of a layer of single-sized dust particles which are coupled to the magnetized gas aerodynamically and the particle-to-gas feedback is included. We find a dispersion relation for axisymmetric linear disturbances and growth rate of the unstable modes are calculated numerically. While the secular gravitational instability in the absence of particle-to-gas feedback predicts the dust layer is unstable, magnetic fields significantly amplifies the instability if the Toomre parameter for the gas component is fixed. We also show that even a weak magnetic field is able to amplify the instability more or less irrespective of the dust-gas coupling.

description: Demand-side management presents significant benefits in reducing the energy load in smart grids by balancing consumption demands or including energy generation and/or storage devices in the user's side. These techniques coordinate the energy load so that users minimize their monetary expenditure. However, these methods require accurate predictions in the energy consumption profiles, which make them inflexible to real demand variations. In this paper we propose a realistic model that accounts for uncertainty in these variations and calculates a robust price for all users in the smart grid. We analyze the existence of solutions for this novel scenario, propose convergent distributed algorithms to find them, and perform simulations considering energy expenditure. We show that this model can effectively reduce the monetary expenses for all users in a real-time market, while at the same time it provides a reliable production cost estimate to the energy supplier.

We discuss this independence in terms of a kind of gauge invariance resulting from energy conservation and extensivity, and demonstrate it numerically for a Lennard-Jones fluid, where different forms of the microscopic energy density lead to different time correlation functions for the heat flux, all of them, however, resulting in the same value for the thermal conductivity.

description: We theoretically investigate nonlinear ballistic thermoelectric transport in a superlattice-structured nanowire. By a special choice of nonuniform widths of the superlattice barriers - analogous to anti-reflection coating in optical systems - it is possible to achieve a transmission which comes close to a square profile as a function of energy. We calculate the low-temperature output power and power-conversion efficiency of a thermoelectric generator based on such a structure and show that the efficiency remains high also when operating at a significant power. To provide guidelines for experiments, we study how the results depend on the nanowire radius, the number of barriers, and on random imperfections in barrier width and separation. Our results indicate that high efficiencies can indeed be achieved with todays capabilities in epitaxial nanowire growth.

Physical Basis for the Symmetries in the Friedmann-Robertson-Walker Metric
Creators: name: Melia, Fulvio
Publisher: name: arXiv
Year: 2016
Subjects: subject: General Physics (physics.gen-ph)
subject: FOS: Physical sciences

description: Modern cosmological theory is based on the Friedmann--Robertson--Walker (FRW) metric. Often written in terms of co-moving coordinates, this well-known solution to Einstein's equations owes its elegant and highly practical formulation to the cosmological principle and Weyl's postulate, upon which it is founded. However, there is physics behind such symmetries, and not all of it has yet been recognized. In this paper, we derive the FRW metric coefficients from the general form of the spherically symmetric line element and demonstrate that, because the co-moving frame also happens to be in free fall, the symmetries in FRW are valid only for a medium with zero active mass. In other words, the spacetime of a perfect fluid in cosmology may be correctly written as FRW only when its equation of state is rho+3p=0, in terms of the total pressure p and total energy density rho. There is now compelling observational support for this conclusion, including the Alcock--Paczynski test, which shows that only an FRW cosmology with zero active mass is consistent with the latest model-independent baryon acoustic oscillation data.

The study then explores a group of related French manuscripts from the early fourteenth century that display similar codicological and palaeographical features and traces their subsequent history in Piedmont in the second half of the fifteenth century. Further, based on palaeographical and textual evidence, it looks at the unique aspects of the local Masoretic tradition of west-central France and the way it was spread.

description: This study investigated the frequency and clinical significance of incidental findings (IFs) in multiparametric prostate magnetic resonance imaging (mpMRI). The study included 426 patients, with 49.8% of them having IFs. The rate of IFs increased with age, and genitourinary IFs accounted for 41.1% of cases, including bladder wall thickness, epididymis cysts, and hydroceles. Extragenitourinary IFs constituted 58.9%, with inguinal hernias being the most common. Among all IFs, 6.9% were clinically significant, including bladder masses, hernias, and other pathological conditions. The study highlights the importance of detecting and managing IFs in prostate MRI, especially in older patients, to facilitate early intervention and improve patient outcomes.Understanding the frequency of incidental findings (IFs) in prostate MRI is crucial for several reasons. Firstly, it helps healthcare professionals and patients to be aware of the potential presence of unexpected abnormalities. Early detection of IFs can lead to timely diagnosis and treatment of underlying conditions, improving patient outcomes. Secondly, recognizing clinically significant IFs among the detected findings is vital. These findings may indicate serious conditions that require immediate attention, such as bladder masses, hernias, or tumors. Identifying and addressing these significant IFs can significantly impact patient care and prognosis. Lastly, studying the prevalence of IFs in prostate MRI contributes to the overall knowledge base, allowing for improved understanding and development of guidelines regarding their management, follow-up, and appropriate communication with patients.

description: The accelerated expansion of the universe is a rather established fact in cosmology and many different models have been proposed as a viable explanation. Many of these models are based on the standard general relativistic framework of non-interacting fluids or more recently of coupled (interacting) dark energy models, where dark energy (the scalar field) is coupled to the dark matter component giving rise to a fifth-force. An interesting alternative is to couple the scalar field directly to the gravity sector via the Ricci scalar. These models are dubbed non-minimally coupled models and give rise to a time-dependent gravitational constant. In this work we study few models falling into this category and describe how observables depend on the strength of the coupling. We extend recent work on the subject by taking into account also the effects of the perturbations of the scalar field and showing their relative importance on the evolution of the mass function. By working in the framework of the spherical collapse model, we show that perturbations of the scalar field have a limited impact on the growth factor (for small coupling constant) and on the mass function with respect to the case where perturbations are neglected.

description: The placebo effect is a fascinating phenomenon that has advanced beyond the medical field into the field of sport and exercise psychology. Preliminary evidence suggests the importance of expectations on the effects of exercise, but the current literature is lacking a strong expectation manipulation and the investigation of cognitive benefits following exercise. To address this gap, 77 young adults (Mage= 29.84, SD = 9.83) were asked to rate the expected cognitive, affective, and physical benefits of a stretching program, and to elaborate on their ratings via an online survey. Participants were randomly allocated to three expectation conditions: expectation-benefit, expectation-no benefit, or no expectation control. All participants were evaluating the same stretching program, but read fictitious testimonies and watched videos that were aimed at manipulating their expectations. Analyses revealed that the expectation-benefit group expected higher cognitive and affective benefits from the stretching program than the expectation-no benefits group (ps < .001). No significant differences emerged on the expectation to receive physical benefits among all three groups. The thematic analysis of participants’ rationale for their ratings revealed that beliefs about benefits were modified through the testimonies and videos provided. Participants also relied on their previous knowledge or experience about stretching to inform their predictions about the expected benefits of the stretching program. Results from this study expand the knowledge on expectations manipulation in exercise settings, and provide exercise professionals with strategies to maximize the benefits participants can receive from exercise.

description: Lovelock theory provides a tractable model of higher-curvature gravity in which several questions can be studied analytically. This is the reason why, in the last years, this theory has become the favorite arena to study the effects of higher-curvature terms in the context of AdS/CFT correspondence. Lovelock theory also admits extensions that permit to accommodate matter coupled to gravity in a non-minimal way. In this setup, problems such as the backreaction of matter on the black hole geometry can also be solved exactly. In this paper, we study the thermodynamics of black holes in theories of gravity of this type, which include both higher-curvature terms, U(1) gauge fields, and conformal couplings with matter fields in D dimensions. These charged black hole solutions exhibit a backreacting scalar field configuration that is regular everywhere outside and on the horizon, and may exist both in asymptotically flat and asymptotically Anti-de Sitter (AdS) spaces. We work out explicitly the boundary action for this theory, which renders the variational problem well-posed and suffices to regularize the Euclidean action in AdS. We also discuss several interrelated properties of the theory, such as its duality symmetry under field redefinition and how it acts on black holes and gravitational wave solutions.

description: Presentation related to https://doi.org/10.52825/cordi.v1i.349 For references, please check the above paper. Abstract The implementation of competencies regarding Research Data Management (RDM) and Data Literacy (DL) into the curricula is a major challenge for the NFDI community. In physics as well as in other disciples, the beginners’ lab courses are the first point in time where students have to deal with data, and are therefore an intuitive point for the integration of first RDM learning objectives. However, the modification of teaching materials is a time-consuming and potentially expensive task. In this contribution the authors show how this can be achieved in the physics beginners’ lab on the basis of concrete examples, thereby affecting the education of students in a wide range of subjects, including the sciences, engineering, but potentially also medicine or geology.

description: We study non-equilibrium steady states (NESS) of spin chains with boundary Markovian dissipation from the computational complexity point of view. We focus on XX chains whose NESS are matrix product operators (MPO), i.e. with coefficients of a tensor operator basis described by transition amplitudes in an auxiliary space. Encoding quantum algorithms in the auxiliary space, we show that estimating expectations of operators, being local in the sense that each acts on disjoint sets of few spins covering all the system, provides the answers of problems at least as hard as, and believed by many computer scientists to be much harder than, those solved by quantum computers. We draw conclusions on the hardness of the above estimations.
