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…
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…
Optimal navigation in a noisy environment
Abhijit Sinha, Sandeep Jangid, Tridib Sadhu +1
Navigating toward a known target in a noisy environment is a fundamental problem shared across biological, physical, and engineered systems. Although optimal strategies are often f…
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…
