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…

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…
