Fluctuating interfaces subject to stochastic resetting
Shamik Gupta, Satya N. Majumdar, Gregory Schehr
We study one-dimensional fluctuating interfaces of length where the interface stochastically resets to a fixed initial profile at a constant rate . For finite in the lim…
Persistent memory in athermal systems in deformable energy landscapes
D. Fiocco, G. Foffi, S. Sastry
We show that memory can be encoded in a model amorphous solid subjected to athermal oscillatory shear deformations, and in an analogous spin model with disordered interactions, sha…
Index Distribution of Cauchy Random Matrices
Ricardo Marino, Satya N. Majumdar, Grégory Schehr +1
Using a Coulomb gas technique, we compute analytically the probability that a large Cauchy random matrix has positive eigenvalues, wh…
Effect of disorder geometry on the critical force in disordered elastic systems
Vincent Démery, Vivien Lecomte, Alberto Rosso
We address the effect of disorder geometry on the critical force in disordered elastic systems. We focus on the model system of a long-range elastic line driven in a random landsca…
Velocity filtration and temperature inversion in a system with long-range interactions
Lapo Casetti, Shamik Gupta
Temperature inversion due to velocity filtration, a mechanism originally proposed to explain the heating of the solar corona, is demonstrated to occur also in a simple paradigmatic…
Classical Heisenberg spins with long-range interactions: Relaxation to equilibrium for finite systems
Julien Barré, Shamik Gupta
Systems with long-range interactions often relax towards statistical equilibrium over timescales that diverge with , the number of particles. A recent work [S. Gupta and D. Muka…
Non-equilibrium statistical mechanics of the heat bath for two Brownian particles
Caterina De Bacco, Fulvio Baldovin, Enzo Orlandini +1
We propose a new look at the heat bath for two Brownian particles, in which the heat bath as a `system' is both perturbed and sensed by the Brownian particles. Non-local thermal fl…
Top eigenvalue of a random matrix: large deviations and third order phase transition
Satya N. Majumdar, Gregory Schehr
We study the fluctuations of the largest eigenvalue of random matrices in the limit of large . The main focus is on Gaussian -ensembles, including in…
Exact domain wall theory for deterministic TASEP with parallel update
J. Cividini, H. J. Hilhorst, C. Appert-Rolland
Domain wall theory (DWT) has proved to be a powerful tool for the analysis of one-dimensional transport processes. A simple version of it was found very accurate for the Totally As…
Dynamics and termination cost of spatially coupled mean-field models
Francesco Caltagirone, Silvio Franz, Richard Morris +1
This work is motivated by recent progress in information theory and signal processing where the so-called `spatially coupled' design of systems leads to considerably better perform…
Viscoelastic Effects in Avalanche Dynamics: A Key to Earthquake Statistics
E. A. Jagla, François P. Landes, Alberto Rosso
In many complex systems a continuous input of energy over time can be suddenly relaxed in the form of avalanches. Conventional avalanche models disregard the possibility of interna…
Non-invasive estimation of dissipation from non-equilibrium fluctuations in chemical reactions
S. Muy, A. Kundu, D. Lacoste
We show how to extract from a sufficiently long time series of stationary fluctuations of chemical reactions an estimate of the entropy production. This method, which is based on r…
Constraint driven condensation in large fluctuations of linear statistics
Juraj Szavits-Nossan, Martin R. Evans, Satya N. Majumdar
Condensation is the phenomenon whereby one of a sum of random variables contributes a finite fraction to the sum. It is manifested as an aggregation phenomenon in diverse physical…
A stochastic model of long-range interacting particles
Shamik Gupta, Thierry Dauxois, Stefano Ruffo
We introduce a model of long-range interacting particles evolving under a stochastic Monte Carlo dynamics, in which possible increase or decrease in the values of the dynamical var…
Quasistationarity in a long-range interacting model of particles moving on a sphere
Shamik Gupta, David Mukamel
We consider a long-range interacting system of particles moving on a spherical surface under an attractive Heisenberg-like interaction of infinite range, and evolving under det…
Nonequilibrium first-order transition in coupled oscillator systems with inertia and noise
Shamik Gupta, Alessandro Campa, Stefano Ruffo
We study the dynamics of a system of coupled oscillators of distributed natural frequencies, by including the features of both thermal noise, parametrized by a temperature, and ine…
Critical line of the scalar field theory on a 4D cubic lattice in the local potential approximation
Jean-Michel Caillol
We establish the critical line of the one-component (or Landau-Ginzburg) model on a simple four dimensional cubic lattice. Our study is performed in the framework of the non-…
Dynamics of a tagged monomer: Effects of elastic pinning and harmonic absorption
Shamik Gupta, Alberto Rosso, Christophe Texier
We study the dynamics of a tagged monomer of a Rouse polymer for different initial configurations. In the case of free evolution, the monomer displays subdiffusive behavior with st…
Conformal Field Theory of Critical Casimir Interactions in 2D
G. Bimonte, T. Emig, M. Kardar
Thermal fluctuations of a critical system induce long-ranged Casimir forces between objects that couple to the underlying field. For two dimensional (2D) conformal field theories (…
Spin clusters and conformal field theory
Gesualdo Delfino, Marco Picco, Raoul Santachiara +1
We study numerically the fractal dimensions and the bulk three-point connectivity for the spin clusters of the Q-state Potts model in two dimensions with . We check…
Universality Classes of Critical Points in Constrained Glasses
Silvio Franz, Giorgio Parisi
We analyze critical points that can be induced in glassy systems by the presence of constraints. These critical points are predicted by the Mean Field Thermodynamic approach and th…
New phase transition in random planar diagrams and RNA-type matching
Andrey Y. Lokhov, Sergei K. Nechaev, Mikhail V. Tamm +1
We study the planar matching problem, defined by a symmetric random matrix with independent identically distributed entries, taking values 0 and 1. We show that the existence of a…
Islands of stability in motif distributions of random networks
M. V. Tamm, A. B. Shkarin, V. A. Avetisov +2
We consider random non-directed networks subject to dynamics conserving vertex degrees and study analytically and numerically equilibrium three-vertex motif distributions in the pr…
Morphology transition at depinning in a solvable model of interface growth in a random medium
Hiroki Ohta, Martin-Luc Rosinberg, Gilles Tarjus
We propose a simple, exactly solvable, model of interface growth in a random medium that is a variant of the zero-temperature random-field Ising model on the Cayley tree. This mode…
