Transport properties of the classical Toda chain: effect of a pinning potential
Abhishek Dhar, Aritra Kundu, Joel L. Lebowitz +1
We consider energy transport in the classical Toda chain in the presence of an additional pinning potential. The pinning potential is expected to destroy the integrability of the s…
Run-and-tumble particle in one-dimensional confining potential: Steady state, relaxation and first passage properties
Abhishek Dhar, Anupam Kundu, Satya N. Majumdar +2
We study the dynamics of a one-dimensional run and tumble particle subjected to confining potentials of the type , with . The noise that drives the particle…
Out of Time Ordered Quantum Dissipation
Bidisha Chakrabarty, Soumyadeep Chaudhuri, R. Loganayagam
We consider a quantum Brownian particle interacting with two harmonic baths, which is then perturbed by a cubic coupling linking the particle and the baths. This cubic coupling ind…
Non-equilibrium dynamics of the piston in the Szilard engine
Deepak Bhat, Abhishek Dhar, Anupam Kundu +1
We consider a Szilard engine in one dimension, consisting of a single particle of mass , moving between a piston of mass , and a heat reservoir at temperature . In additio…
Derivation of fluctuating hydrodynamics and crossover from diffusive to anomalous transport in a hard-particle gas
Asaf Miron, Julien Cividini, Anupam Kundu +1
A recently developed non-linear fluctuating hydrodynamics theory has been quite successful in describing various features of anomalous energy transport. However the diffusion and t…
Fractional diffusion equation description of an open anomalous heat conduction set-up
Aritra Kundu, Cédric Bernardin, Keji Saito +2
We provide a stochastic fractional diffusion equation description of energy transport through a finite one-dimensional chain of harmonic oscillators with stochastic momentum exchan…
Temperature dependence of butterfly effect in a classical many-body system
Thomas Bilitewski, Subhro Bhattacharjee, Roderich Moessner
We study the chaotic dynamics in a classical many-body system of interacting spins on the kagome lattice. We characterise many-body chaos via the butterfly effect as captured by an…
Quantum quench and thermalization of one-dimensional Fermi gas via phase space hydrodynamics
Manas Kulkarni, Gautam Mandal, Takeshi Morita
By exploring a phase space hydrodynamics description of one-dimensional free Fermi gas, we discuss how systems settle down to steady states described by the generalized Gibbs ensem…
Motion of a Brownian molecule in the presence of reactive boundaries
Arnab Pal, Isaac Pérez Castillo, Anupam Kundu
We study the one-dimensional motion of a Brownian particle inside a confinement described by two reactive boundaries which can partially reflect or absorb the particle. Understandi…
Anomalous heat equation in a system connected to thermal reservoirs
Priyanka, Aritra Kundu, Abhishek Dhar +1
We study anomalous transport in a one-dimensional system with two conserved quantities in presence of thermal baths. In this system we derive exact expressions of the temperature p…
