Universality of shocks in conserved driven single-file motions with bottlenecks
Sourav Pal, Abhik Basu
Driven single-file motion, in which particles move unidirectionally along one-dimensional channels, sets the paradigm for wide variety of one-dimensional directed movements, rangin…
Stationary densities and delocalized domain walls in asymmetric exclusion processes competing for finite pools of resources
Sourav Pal, Parna Roy, Abhik Basu
We explore the stationary densities and domain walls in the steady states of a pair of asymmetric exclusion processes (TASEP) antiparallelly coupled to two particle reservoirs with…
Stationary densities in a weakly nonconserving asymmetric exclusion processes with finite resources
Sourav Pal, Abhik Basu
Asymmetric exclusion process (TASEP) along a one-dimensional (1D) open channel sets the paradigm for 1D driven models and nonequilibrium phase transitions in open 1D models. Inspir…
Anisotropy can make a moving active fluid membrane rough or crumpled
Debayan Jana, Astik Haldar, Abhik Basu
We present a hydrodynamic theory of anisotropic and inversion-asymmetric moving active permeable fluid membranes. These are described by an anisotropic Kardar-Parisi-Zhang equation…
Logarithmic or algebraic: roughening of an active Kardar-Parisi-Zhang surface
Debayan Jana, Astik Haldar, Abhik Basu
The Kardar-Parisi-Zhang (KPZ) equation sets the universality class for growing and roughening of nonequilibrium surfaces without any conservation law and nonlocal effects. We argue…
Rough or crumpled: Strong coupling phases of a generalized Kardar-Parisi-Zhang surface
Debayan Jana, Abhik Basu
We study a generalized Kardar-Parisi-Zhang (KPZ) equation [Jana et al., Phys. Rev. E 109, L032104 (2024)] that sets the paradigm for universality in roughening of growing nonequili…
