Universal properties of the Kardar-Parisi-Zhang equation with quenched columnar disorders
Astik Haldar
Inspired by the recent results on totally asymmetric simple exclusion processes on a periodic lattice with short-ranged quenched hopping rates [A. Haldar, A. Basu, Phys Rev Researc…

Marching on a rugged landscape: Universality in disordered asymmetric exclusion processes
Astik Haldar, Abhik Basu
We develop the hydrodynamic theory for number conserving asymmetric exclusion processes with short-range random quenched disordered hopping rates, which is one-dimensional Kardar-P…

Flow can order: Phases of live XY spins in two dimensions
Astik Haldar, Abhik Basu
We present the hydrodynamic theory of active XY spins coupled with flow fields, for systems both having and or lacking number conservation in two dimensions (2D). For the latter, w…
