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…
Steady-state density large deviations in driven diffusive systems
Soumyabrata Saha, Tridib Sadhu
A diffusive system coupled to boundary reservoirs reaches a non-equilibrium steady state whose density fluctuations can exhibit correlations over macroscopic distances. While curre…
Hydrodynamics of a hard-core active lattice gas
Ritwik Mukherjee, Soumyabrata Saha, Tridib Sadhu +2
We present a fluctuating hydrodynamic description of an active lattice gas model with excluded volume interactions that exhibits motility-induced phase separation under appropriate…
Large deviations of current for the symmetric simple exclusion process on a semi-infinite line, and on an infinite line with a slow bond
Kapil Sharma, Soumyabrata Saha, Sandeep Jangid +1
Two influential exact results in classical one-dimensional diffusive transport are about current statistics for the symmetric simple exclusion process: one in the stationary state…
Large Deviations in the Symmetric Simple Exclusion Process with Slow Boundaries: A Hydrodynamic Perspective
Soumyabrata Saha, Tridib Sadhu
We revisit the one-dimensional model of the symmetric simple exclusion process slowly coupled with two unequal reservoirs at the boundaries. In its non-equilibrium stationary state…
Current fluctuations in a semi-infinite line
Soumyabrata Saha, Tridib Sadhu
We present the application of a fluctuating hydrodynamic theory to study current fluctuations in diffusive systems on a semi-infinite line in contact with a reservoir with slow cou…
