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…
Strong coupling phases of conserved growth models are crumpled
Debayan Jana, Abhik Basu
We show that stochastically driven nonequilibrium conserved growth models admit generic strong coupling phases for sufficiently strong nonlocal chemical potentials underlying the d…
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…
