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…
Kolmogorov or Bolgiano-Obukhov: Universal scaling in stably stratified turbulent fluids
Abhik Basu, Jayanta K Bhattacharjee
We set up the scaling theory for stably stratified turbulent fluids. For a system having infinite extent in the horizontal directions, but with a finite width in the vertical direc…
Casimir stresses in active nematic films
Abhik Basu, Jean-Francois Joanny, Frank Jülicher +1
We calculate the Casimir stresses in a thin layer of active fluid with nematic order. By using a stochastic hydrodynamic approach for an active fluid layer of finite thickness ,…
Pinned or moving: states of a single shock in a ring
Parna Roy, Anjan Kumar Chandra, Abhik Basu
Totally asymmetric exclusion processes (TASEP) with open boundaries are known to exhibit moving shocks or delocalised domain walls (DDW) for sufficiently small equal injection and…
Statistical mechanics of asymmetric tethered membranes: spiral and crumpled phases
Tirthankar Banerjee, Niladri Sarkar, John Toner +1
We develop the elastic theory for inversion-asymmetric tethered membranes and use it to identify and study their possible phases. Asymmetry in a tethered membrane causes spontaneou…
