Macroscopic fluctuation theory for the multi-time statistics of current in non-stationary diffusive systems
Sabyasachi Chowdhury, Kapil Sharma, Sandeep Jangid +1
The statistics of current fluctuations has long been a central object of study in non-equilibrium physics. Most existing work has focused on one-time statistics, while their multi-…
An exactly solvable macroscopic fluctuation theory of single-file diffusion
Sandeep Jangid, Soumyabrata Saha, Kapil Sharma +4
The authors present an exact solution of macroscopic fluctuation theory for single‑file diffusion of extended Brownian hard rods, deriving large‑deviation statistics for tracer pos…
Effect of slow bonds on current fluctuations in the symmetric simple exclusion process
Soumyabrata Saha, Sandeep Jangid, Kapil Sharma +1
The symmetric simple exclusion process (SSEP) is a paradigmatic model of classical non-equilibrium dynamics. Exact results for large deviations of particle current in the SSEP have…
Universal tracer statistics in single-file transport
Soumyabrata Saha, Jitendra Kethepalli, Benjamin Guiselin +2
We uncover an emergent universality in the large-scale, long-time statistics of a one-dimensional hard-rod gas evolving under two fundamentally different classes of microscopic dyn…
Large deviations of density in the non-equilibrium steady state of boundary-driven diffusive systems
Soumyabrata Saha, Tridib Sadhu
A diffusive system coupled to unequal boundary reservoirs reaches a non-equilibrium steady state. While the full-counting-statistics of current fluctuations in these states are wel…
A bottom-up approach to fluctuating hydrodynamics: Coarse-graining of stochastic lattice gases and the Dean-Kawasaki equation
Soumyabrata Saha, Sandeep Jangid, Thibaut Arnoulx de Pirey +2
Fluctuating hydrodynamics provides a quantitative, large-scale description of many-body systems in terms of smooth variables, with microscopic details entering only through a small…
