Probing fluctuating hydrodynamics through current fluctuations in hard rod gas
Tirthankar Mondal, Indranil Mukherjee, Anupam Kundu
We study the full counting statistics of the integrated current in a one-dimensional hard-rod gas in equilibrium, employing two recently proposed fluctuating hydrodynamic framework…
Quasiparticle Diffusion for the Toda Fluid in Equilibrium
Seema Chahal, Alberto Brollo, Indranil Mukherjee +3
Many-body integrable systems can be understood as a gas of quasiparticles. They propagate ballistically and drive large-scale transport. However, with the exception of the hard rod…
Quasiparticle dynamics and diffusive scale hydrodynamics in an inhomogeneous gas of hard rods
Anupam Kundu
We investigate the stochastic dynamics of quasiparticles within a gas of hard rods in one dimension for two choices of initial states: one with long-range correlations and the othe…
Microscopic and hydrodynamic correlation in 1d hard rod gas
Indranil Mukherjee, Seema Chahal, Anupam Kundu
We compute mass density correlations of a one-dimensional gas of hard rods at both microscopic and macroscopic scales. We provide exact analytical calculations of the microscopic c…
Stochastic dynamics of quasiparticles in the hard rod gas
Seema Chahal, Indranil Mukherjee, Abhishek Dhar +2
We consider a one-dimensional gas of hard rods, one of the simplest examples of an interacting integrable model. It is well known that the hydrodynamics of such integrable models c…
Ballistic macroscopic fluctuation theory of correlations in hard rod gas
Anupam Kundu
Recently, a theoretical framework known as {\it ballistic macroscopic fluctuation theory} has been developed to study large-scale fluctuations and correlations in many-body systems…
Inertial Dynamics of Run-and-Tumble Particle
Debraj Dutta, Anupam Kundu, Urna Basu
We study the dynamics of a single inertial run-and-tumble particle on a straight line. The motion of this particle is characterized by two intrinsic time-scales, namely, an inertia…
Conserved densities of hard rods: microscopic to hydrodynamic solutions
Mrinal Jyoti Powdel, Anupam Kundu
We consider a system of many hard rods moving in one dimension. As it is an integrable system, it possesses an extensive number of conserved quantities and its evolution on macrosc…
Tagged particle in single-file diffusion with arbitrary initial conditions
Julien Cividini, Anupam Kundu
We compute the full probability distribution of the positions of a tagged particle exactly for given arbitrary initial positions of the particles and for general single-particle pr…
Energy versus information based estimations of dissipation using a pair of magnetic colloidal particles
S. Tusch, A. Kundu, G. Verley +5
Using the framework of stochastic thermodynamics, we present an experimental study of a doublet of magnetic colloidal particles which is manipulated by a time-dependent magnetic fi…
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…
