Classical 'spin' filtering with two degrees of freedom and dissipation
Atul Varshney, Areg Ghazaryan, Artem G. Volosniev
Coupling of angular motion to a spin degree of freedom gives rise to various transport phenomena in quantum systems that are beyond the standard paradigms of classical physics. Her…
Re-laminarization of elastic turbulence
M. Vijay Kumar, Atul Varshney, Dongyang Li +1
We report frictional drag reduction and a complete flow re-laminarization of elastic turbulence (ET) at vanishing inertia in a viscoelastic channel flow past an obstacle. We show t…
Experimental observation of the origin and structure of elasto-inertial turbulence
George H. Choueiri, Jose M. Lopez, Atul Varshney +2
Turbulence generally arises in shear flows if velocities and hence inertial forces are sufficiently large. In striking contrast, viscoelastic fluids can exhibit disordered motion e…
Nonlinear hydrodynamic instability and turbulence in pulsatile flow
Duo Xu, Atul Varshney, Xingyu Ma +4
Pulsating flows through tubular geometries are laminar provided that velocities are moderate. This in particular is also believed to apply to cardiovascular flows where inertial fo…
Stokes flow analogous to viscous electron current in graphene
Jonathan Mayzel, Victor Steinberg, Atul Varshney
Electron transport in two-dimensional conducting materials such as graphene, with dominant electron-electron interaction, exhibits unusual vortex flow that leads to a nonlocal curr…
Elastic Alfven waves in elastic turbulence
Atul Varshney, Victor Steinberg
Speed of sound waves in gases and liquids is governed by medium compressibility. There exists another type of non-dispersive waves which speed depends on stress instead of medium e…
