Dynamical symmetries of Markov processes with multiplicative white noise
Camille Aron, Daniel G. Barci, Leticia F. Cugliandolo +2
We analyse various properties of stochastic Markov processes with multiplicative white noise. We take a single-variable problem as a simple example, and we later extend the analysi…
The Neutrino Opacity of Neutron Star Inner Crust
P. N. Alcain, C. O. Dorso
The study of neutron rich matter, present in neutron star, proto-neutron stars and core-collapse supernovae, can lead to further understanding of the behavior of nuclear matter in…
Implications of the scalar tilt for the tensor-to-scalar ratio
Paolo Creminelli, Sergei Dubovsky, Diana López Nacir +4
We investigate the possible implications of the measured value of the scalar tilt for the tensor-to-scalar ratio in slow-roll, single-field inflationary models. The measu…
Minimal Log Gravity
Gaston Giribet, Yerko Vásquez
Minimal Massive Gravity (MMG) is an extension of three-dimensional Topologically Massive Gravity that, when formulated about Anti-de Sitter space, accomplishes to solve the tension…
Shock-waves and commutation speed of memristors
Shao Tang, Federico Tesler, Fernando Gomez Marlasca +3
Progress of silicon based technology is nearing its physical limit, as minimum feature size of components is reaching a mere 10 nm. The resistive switching behaviour of transition…
New analytic solution for the heat flow through a general harmonic network
Nahuel Freitas, Juan Pablo Paz
We present a new analytic expression for the heat current through a general harmonic network coupled with Ohmic reservoirs. We use a new method that enables us to express the stati…
Aspects of electrostatics in BTZ geometries
Y. Herrera, V. Hurovich, O. Santillán +1
In the present paper the electrostatic of charges in non rotating BTZ black hole and wormhole space times is studied. In particular, the self force of a point charge in the geometr…
Vibrating Rays Theory
Luis Bilbao, Luis Bernal, Fernando Minotti
The present work is aimed to explain why we started to consider Vibrating Rays Theory (VRT) as a viable representation of nature, and to elaborate some of its consequences. In 1846…
Interacting parametrized post-Friedmann method
Martín G. Richarte, Lixin Xu
We apply the interacting parametrized post-Friedmann (IPPF) method to a coupled dark energy model where the interaction is proportional to dark matter density at background level.…
Mining the modular structure of protein interaction networks
Ariel Berenstein, Janet Piñero, Laura Ines Furlong +1
Cluster-based descriptions of biological networks have received much attention in recent years fostered by accumulated evidence of the existence of meaningful correlations between…
Kelvin-Helmholtz versus Hall Magneto-shear instability in astrophysical flows
Daniel O. Gomez, Cecilia Bejarano, Pablo D. Mininni
We study the stability of shear flows in a fully ionized plasma. Kelvin-Helmholtz is a well known, macroscopic and ideal shear-driven instability. In sufficiently low density plasm…
Numerical integration of the stochastic Landau-Lifshitz-Gilbert equation in generic time-discretisation schemes
Federico Romá, Leticia F. Cugliandolo, Gustavo S. Lozano
We introduce a numerical method to integrate the stochastic Landau-Lifshitz-Gilbert equation in spherical coordinates for generic discretization schemes. This method conserves the…
Interacting dark sector with transversal interaction
Luis P. Chimento, Martín G. Richarte
We investigate the interacting dark sector composed of dark matter, dark energy, and dark radiation for a spatially flat Friedmann-Robertson-Walker (FRW) background by introducing…
Nonlinear effects of dark energy clustering beyond the acoustic scales
Stefano Anselmi, Diana López Nacir, Emiliano Sefusatti
We extend the resummation method of Anselmi & Pietroni (2012) to compute the total density power spectrum in models of quintessence characterized by a vanishing speed of sound. For…
Shedding light on the asymmetry: the photon handle
J. A. Aguilar-Saavedra, E. Alvarez, A. Juste +1
We investigate a charge asymmetry in production at the LHC that provides complementary information to the measured asymmetries in production. We estimate th…
A hydrodynamic approach to boost invariant free streaming
Esteban Calzetta
We consider a family of exact boost invariant solutions of the transport equation for free streaming massless particles, where the one particle distribution function is defined in…
Magnetization dynamics: path-integral formalism for the stochastic Landau-Lifshitz-Gilbert equation
Camille Aron, Daniel G. Barci, Leticia F. Cugliandolo +2
We construct a path-integral representation of the generating functional for the dissipative dynamics of a classical magnetic moment as described by the stochastic generalization o…
Corrections to the Berry phase in a solid-state qubit due to low-frequency noise
Fernando C. Lombardo, Paula I. Villar
We present a quantum open-system approach to analyze the nonunitary dynamics of a superconducting qubit when it evolves under the influence of external noise. We consider the prese…
Hartree approximation in curved spacetimes revisited II: The semiclassical Einstein equations and de Sitter self-consistent solutions
Diana L. López Nacir, Francisco D. Mazzitelli, Leonardo G. Trombetta
We consider the semiclassical Einstein equations (SEE) in the presence of a quantum scalar field with self-interaction . Working in the Hartree truncation of the two-particle…
Long-term memory in experiments and numerical simulations of hydrodynamic and magnetohydrodynamic turbulence
Pablo Mininni, Pablo Dmitruk, Philippe Odier +5
We analyze time series stemming from experiments and direct numerical simulations of hydrodynamic and magnetohydrodynamic turbulence. Simulations are done in periodic boxes, but wi…
Logarithmic AdS Waves and Zwei-Dreibein Gravity
Eric A. Bergshoeff, Andrés F. Goya, Wout Merbis +1
We show that the parameter space of Zwei-Dreibein Gravity (ZDG) in AdS3 exhibits critical points, where massive graviton modes coincide with pure gauge modes and new `logarithmic'…
Formulation of the twisted-light--matter interaction at the phase singularity: the twisted-light gauge
G. F. Quinteiro, D. E. Reiter, T. Kuhn
Twisted light is light carrying orbital angular momentum. The profile of such a beam is a ring-like structure with a node at the beam axis, where a phase singularity exits. Due to…
Hairy black holes sourced by a conformally coupled scalar field in D dimensions
Gaston Giribet, Matias Leoni, Julio Oliva +1
There exist well-known no-hair theorems forbidding the existence of hairy black hole solutions in general relativity coupled to a scalar conformal field theory in asymptotically fl…
