Mutual Information of Generalized Free Fields

Valentin Benedetti, Horacio Casini, Pedro J. Martinez

We study generalized free fields (GFF) from the point of view of information measures. We first review conformal GFF, their holographic representation, and the ambiguities in the a…

Pacman geometries and the Hayward term in JT gravity

Raúl Arias, Marcelo Botta-Cantcheff, Pedro J. Martinez

We study the Hayward term describing corners in the boundary of the geometry in the context of the Jackiw-Teitelboim gravity. These corners naturally arise in the computation of Ha…

Thermalization of Holographic Excited States

Pedro J. Martinez, Guillermo A. Silva

We propose a real time holographic framework to study thermalization processes of a family of QFT excited states. The construction builds on Skenderis-van Rees's holographic duals…

Entropic order parameters in weakly coupled gauge theories

Horacio Casini, Javier M. Magan, Pedro J. Martinez

The entropic order parameters measure in a universal geometric way the statistics of non-local operators responsible for generalized symmetries. In this article, we compute entropi…

Rényi entropies and area operator from gravity with Hayward term

Marcelo Botta-Cantcheff, Pedro J. Martinez, Juan F. Zarate

In the context of the holographic duality, the entanglement entropy of ordinary QFT in a subregion in the boundary is given by a quarter of the area of an minimal surface embedded…

Modular Hamiltonian for (holographic) excited states

Raúl Arias, Marcelo Botta-Cantcheff, Pedro J. Martinez +1

In this work we study the Tomita-Takesaki construction for a family of excited states that, in a strongly coupled CFT - at large -, correspond to coherent states in an asymptoti…

Holographic excited states in AdS Black Holes

Marcelo Botta-Cantcheff, Pedro J. Martínez, Guillermo A. Silva

We have recently presented a geometry dual to a Schwinger-Keldysh closed time contour, with two equal length Euclidean sections, which can be thought of as dual to the Thermo…

The Gravity Dual of Real-Time CFT at Finite Temperature

Marcelo Botta-Cantcheff, Pedro J. Martínez, Guillermo A. Silva

We present a spherically symmetric aAdS gravity solution with Schwinger-Keldysh boundary condition dual to a CFT at finite temperature defined on a complex time contour. The geomet…

Interacting fields in real-time AdS/CFT

Marcelo Botta-Cantcheff, Pedro J. Martínez, Guillermo A. Silva

We compute time-ordered 2- and 3-pt correlation functions of CFT scalar operators between generic in/out states. The calculation is holographically carried out by considering a non…

On excited states in real-time AdS/CFT

Marcelo Botta-Cantcheff, Pedro J. Martínez, Guillermo A. Silva

The Skenderis-van Rees prescription, which allows the calculation of time-ordered correlation functions of local operators in CFT's using holographic methods is studied and applied…

Impulse-Induced Optimum Signal Amplification in Scale-Free Networks

Pedro J. Martínez, Ricardo Chacón

Optimizing information transmission across a network is an essential task for controlling and manipulating generic information-processing systems. Here, we show how topological amp…

Drastic disorded-induced reduction of signal amplification in scale-free networks

Ricardo Chacón, Pedro J. Martínez

Understanding information transmission across a network is a fundamental task for controlling and manipulating both biological and man-made information processing systems. Here, we…

Reply to Comment on `Ratchet universality in the presence of thermal noise'

Pedro J. Martínez, Ricardo Chacón

The Comment by Quintero et al (arXiv:1309.1065[nlin.PS])does not dispute the central result of our paper [Phys. Rev. E {87}, 062114 (2013)] which is a theory explaining the interpl…

Ratchet universality in the presence of thermal noise

Pedro J. Martínez, Ricardo Chacón

We show that directed ratchet transport of a driven overdamped Brownian particle subjected to a spatially periodic and symmetric potential can be reliably controlled by tailoring a…

Mode-Locking of mobile discrete breathers

D. Zueco, P. J. Martinez, L. M. Floria +1

We study numerically synchronization phenomena of mobile discrete breathers in dissipative nonlinear lattices periodically forced. When varying the driving intensity, the breather…

Discrete breathers in dissipative lattices

J. L. Marin, F. Falo, P. J. Martinez +1

We study the properties of discrete breathers, also known as intrinsic localized modes, in the one-dimensional Frenkel-Kontorova lattice of oscillators subject to damping and exter…

Ratchet potential for fluxons in Josephson-Junction arrays

Fernando Falo, Pedro J. Martinez, Juan J. Mazo +1

We propose a simple configuration of a one-dimensional parallel array of Josephson junctions in which the pinning potential for trapped fluxons lacks inversion symmetry (ratchet po…

Intrinsically localized chaos in discrete nonlinear extended systems

P. J. Martinez, L. M. Floria, F. Falo +1

The phenomenon of intrinsic localization in discrete nonlinear extended systems, i.e. the (generic) existence of discrete breathers, is shown to be not restricted to periodic solut…
