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…
