Boltzmann-Loschmidt dispute reloaded quantum 150 years later
Leonardo Ermann, Alexei D. Chepelianskii, Dima L. Shepelyansky
The Boltzmann-Loschmidt dispute of 1876 questioned the possibility of a statistical irreversible description by time reversible classical equations of motion of atoms. Here we show…
Three faces of random walks in a hyperbolic domain: BKT, Lifshitz tails, and KPZ
Daniil Fedotov, Sergei Nechaev
We show that continuous random walks (diffusion) in the Poincaré upper half-plane provide a unified description of three seemingly unrelated phenome…
Probing phase transitions of finite directed polymers near a corrugated wall via two-replica analysis
Ruijie Xu, Sergei Nechaev
We study the pinning transition in a (1+1)-dimensional lattice model of a fluctuating interface interacting with a corrugated impenetrable wall. The interface is modeled as an -…
Dynamically emergent correlations in a Brownian gas with diffusing diffusivity
Nikhil Mesquita, Satya N. Majumdar, Sanjib Sabhapandit
We study a gas of Brownian particles in the presence of a common stochastic diffusivity , where represents a one-dimensional Brownian motion at time . St…
Dynamical thermalization, Rayleigh-Jeans condensate, vortexes and wave collapse in quantum chaos fibers and fluid of light
Leonardo Ermann, Alexei D. Chepelianskii, Dima L. Shepelyansky
We study analytically and numerically the time evolution of a nonlinear field described by the nonlinear Schrödinger equation in a chaotic -shape billiard. In absence of nonline…
Extreme value statistics in a continuous time branching process: a pedagogical primer
Satya N. Majumdar, Alberto Rosso
We study a continuous time branching process where an individual splits into two daughters with rate b and dies with rate a, starting from a single individual at t=0. We show that…
The cost of resetting discrete-time random walks
John C. Sunil, Richard A. Blythe, Martin R. Evans +1
We consider a discrete-time continuous-space random walk, with a symmetric jump distribution, under stochastic resetting. Associated with the random walker are cost functions for j…
Exact height distribution in one-dimensional Edwards-Wilkinson interface with diffusing diffusivity
David S. Dean, Satya N. Majumdar, Sanjib Sabhapandit
We study the height distribution of a one-dimensional Edwards-Wilkinson interface in the presence of a stochastic diffusivity , where represents a one-dimension…
Large Deviations in Switching Diffusion: from Free Cumulants to Dynamical Transitions
Mathis Guéneau, Satya N. Majumdar, Gregory Schehr
We study the diffusion of a particle with a time-dependent diffusion constant that switches between random values drawn from a distribution at a fixed rate . Using…
Dynamical phase transitions in certain non-ergodic stochastic processes
Yogeesh Reddy Yerrababu, Satya N. Majumdar, Benjamin Guiselin +1
We present a class of stochastic processes in which the large deviation functions of time-integrated observables exhibit singularities that relate to dynamical phase transitions of…
Exact joint distributions of three global characteristic times for Brownian motion
Alexander K. Hartmann, Satya N. Majumdar
We consider three global characteristic times for a one-dimensional Brownian motion in the interval : the occupation time denoting the cumulative tim…
Macroscopic Quantum States and Universal Correlations in a Disorder-Order Interface Propagating over a 1D Ground State
Vanja Marić, Florent Ferro, Maurizio Fagotti
We consider translationally invariant quantum spin- chains with local interactions and a discrete symmetry that is spontaneously broken at zero temperature. We envisio…
The number of minima in random landscapes generated by constrained random walk and Lévy flights: universal properties
Anupam Kundu, Satya N. Majumdar, Gregory Schehr
We provide a uniform framework to compute the exact distribution of the number of minima/maxima in three different random walk landscape models in one dimension. The landscape is g…
Power-law relaxation of a confined diffusing particle subject to resetting with memory
Denis Boyer, Satya N. Majumdar
We study the relaxation of a Brownian particle with long range memory under confinement in one dimension. The particle diffuses in an arbitrary confining potential and resets at ra…
Minimizing the Profligacy of Searches with Reset
John C. Sunil, Richard A. Blythe, Martin R. Evans +1
We introduce the profligacy of a search process as a competition between its expected cost and the probability of finding the target. The arbiter of the competition is a parameter…
Full counting statistics of 1d short-range Riesz gases in confinement
Jitendra Kethepalli, Manas Kulkarni, Anupam Kundu +3
We investigate the full counting statistics (FCS) of a harmonically confined 1d short-range Riesz gas consisting of particles in equilibrium at finite temperature. The particle…
Work Distribution for Unzipping Processes
P. Werner, A. K. Hartmann, S. N. Majumdar
A simple zipper model is introduced, representing in a simplified way, e.g., the folded DNA double helix or hairpin structures in RNA. The double stranded hairpin is connected to a…
Fate of Boltzmann's breathers: Stokes hypothesis and anomalous thermalization
M. I. García de Soria, P. Maynar, David Guéry-Odelin +1
Boltzmann showed that in spite of momentum and energy redistribution through collisions, a rarefied gas confined in a isotropic harmonic trapping potential does not reach equilibri…
Dynamically emergent correlations between particles in a switching harmonic trap
Marco Biroli, Manas Kulkarni, Satya N. Majumdar +1
We study a one dimensional gas of noninteracting diffusing particles in a harmonic trap, whose stiffness switches between two values and with constant rates a…
Active particle in one dimension subjected to resetting with memory
Denis Boyer, Satya N. Majumdar
The study of diffusion with preferential returns to places visited in the past has attracted an increased attention in recent years. In these highly non-Markov processes, a standar…
