Equivalent Markov processes under gauge group
M. Caruso, C. Jarne
We have studied Markov processes on denumerable state space and continuous time. We found that all these processes are connected via gauge transformations. We have used this result…
A planar doublebox in canonical form
Marco S. Bianchi, Matias Leoni
We consider a planar doublebox with four massive external momenta and two massive internal propagators. We derive the system of differential equations for the relevant master integ…
A functional renormalization method for wave propagation in random media
Federico Lamagna, Esteban Calzetta
We develop the exact renormalization group approach as a way to evaluate the effective speed of propagation of a scalar wave in a medium with random inhomogeneities. We use the Mar…
Quantum Friction in Arbitrarily Directed Motion
J. Klatt, M. B. Farias, D. A. R. Dalvit +1
Quantum friction, the electromagnetic fluctuation-induced frictional force decelerating an atom which moves past a macroscopic dielectric body, has so far eluded experimental evide…
Quantum friction between graphene sheets
M. Belén Farias, César D. Fosco, Fernando C. Lombardo +1
We study the Casimir friction phenomenon in a system consisting of two flat, infinite, and parallel graphene sheets, which are coupled to the vacuum electromagnetic (EM) field. Tho…
Fractional spin and Josephson effect in time-reversal-invariant topological superconductors
Alberto Camjayi, Liliana Arrachea, Armando Aligia +1
Time reversal invariant topological superconducting (TRITOPS) wires are known to host a fractional spin hbar/4 at their ends. We investigate how this fractional spin affects the Jo…
Non-linear coupling in the dark sector as a running vacuum model
Josue De-Santiago, Iván E. Sánchez G., David Tamayo
In this work we study a phenomenological non-gravitational interaction between dark matter and dark energy. The scenario studied in this work extends the usual interaction model pr…
Holographic Ward identities for symmetry breaking in two dimensions
Riccardo Argurio, Gaston Giribet, Andrea Marzolla +2
We investigate symmetry breaking in two-dimensional field theories which have a holographic gravity dual. Being at large N, the Coleman theorem does not hold and Goldstone bosons a…
Dynamical signatures of structural connectivity damage to a model of the brain posed at criticality
Ariel Haimovici, Pablo Balenzuela, Enzo Tagliazucchi
Synchronization of brain activity fluctuations is believed to represent communication between spatially distant neural processes. These inter-areal functional interactions develop…
Quantum to classical transition in the work distribution for chaotic systems
Ignacio García-Mata, Augusto J. Roncaglia, Diego A. Wisniacki
The work distribution is a fundamental quantity in nonequilibrium thermodynamics mainly due to its connection with fluctuations theorems. Here we develop a semiclassical approximat…
Sets of FCS experiments to quantify free diffusion coefficients in reaction-diffusion systems. The case of Ca2+ and its dyes
Lorena Sigaut, Cecilia Villarruel, María Laura Ponce +1
Many cell signaling pathways involve the diffusion of messengers that bind/unbind to intracellular components. Quantifying their net transport rate under different conditions, then…
Graphical analysis of Current-Voltage Characteristics in Typical Memristive Interfaces
C. Acha
A graphical representation based on the isothermal current-voltage (IV) measurements of typical memristive interfaces is presented. This is the starting point to extract relevant m…
Search for sharp and smooth spectral signatures of SSM gravitino dark matter with Fermi-LAT
German A. Gomez-Vargas, Daniel E. Lopez-Fogliani, Carlos Munoz +2
The SSM solves the problem of supersymmetric models and reproduces neutrino data, simply using couplings with right-handed neutrinos 's. Given that these couplings break…
Ultrasensitivity on signaling cascades revisited: Linking local and global ultrasensitivity estimations
Edgar Altszyler, Alejandra Ventura, Alejandro Colman-Lerner +1
Ultrasensitive response motifs, which are capable of converting graded stimulus in binary responses, are very well-conserved in signal transduction networks. Although it has been s…
Anderson-Mott transition in a disordered Hubbard model with correlated hopping
Francesca Battista, Alberto Camjayi, Liliana Arrachea
We study the ground state phase diagram of the Anderson-Hubbard model with correlated hopping at half filling in one-dimension. The Hamiltonian has a local Coulomb repulsion an…
Room evacuation through two contiguous exits
I. M. Sticco, G. A. Frank, C. O. Dorso
Current regulations demand that at least two exits should be available for a safe evacuation during a panic situation. Although the "faster is slower" effect is expected to take pl…
Fundamental limits for cooling of linear quantum refrigerators
Nahuel Freitas, Juan Pablo Paz
We study the asymptotic dynamics of arbitrary linear quantum open systems which are periodically driven while coupled with generic bosonic reservoirs. We obtain exact results for t…
Extended Symmetries at the Black Hole Horizon
Laura Donnay, Gaston Giribet, Hernán A. González +1
We prove that non-extremal black holes in four-dimensional general relativity exhibit an infinite-dimensional symmetry in their near horizon region. By prescribing a physically sen…
Modeling Opinion Dynamics: Theoretical analysis and continuous approximation
Juan Pablo Pinasco, Viktoriya Semeshenko, Pablo Balenzuela
Frequently we revise our first opinions after talking over with other individuals because we get convinced. Argumentation is a verbal and social process aimed at convincing. It inc…
Fermion zero modes in a vortex background
Gustavo Lozano, Azadeh Mohammadi, Fidel A. Schaposnik
In this paper we study the zero energy solutions of the Dirac equation in the background of a vortex of a non-Abelian gauge model with three charged scalar fields. We determi…
About the isocurvature tension between axion and high scale inflationary models
Mariel Estevez, O. Santillán
The present work suggests that the isocurvature tension between axion and high energy inflationary scenarios may be avoided by considering a double field inflationary model involvi…
Precision Studies of Observables in pp->W->l nu and pp->gamma,Z->l+l- processes at the LHC
S. Alioli, A. B. Arbuzov, D. Yu. Bardin +33
This report was prepared in the context of the LPCC "Electroweak Precision Measurements at the LHC WG" and summarizes the activity of a subgroup dedicated to the systematic compari…
Tridimensional to bidimensional transition in magnetohydrodynamic turbulence with a guide field and kinetic helicity injection
N. E. Sujovolsky, P. D. Mininni
We study the transition in dimensionality of a three-dimensional magnetohydrodynamic flow forced only mechanically, when the strength of a magnetic guiding field is gradually incre…
An exact limit of ABJM
Marco S. Bianchi, Matias Leoni
We study planar ABJM in a limit where one coupling is negligible compared to the other. We provide a recipe for exactly solving the expectation value of bosonic BPS Wilson loops on…
