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…
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…
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…
