Superfluidity in active quantum flocks
Byjesh N. Radhakrishnan, Reyhaneh Khasseh, Thomas Schmidt +1
Active quantum matter has very recently emerged at the intersection between bio- and quantum many-body physics, combining the self-organization of living systems with the coherence…
Irreversibility in scalar active turbulence: The role of topological defects
Byjesh N. Radhakrishnan, Francesco Serafin, Thomas L. Schmidt +1
In many active systems, swimmers collectively stir the surrounding fluid to stabilize some self-sustained vortices. The resulting nonequilibrium state is often referred to as activ…
Confinement induced three-dimensional trajectories of microswimmers in rectangular channels
Byjesh N. Radhakrishnan, Ahana Purushothaman, Ranabir Dey +1
We study the trajectories of a model microorganism inside three-dimensional channels with square and rectangular cross-sections. Using (i) numerical simulations based on lattice-Bo…
Hydrodynamic Navier-Stokes equations in two-dimensional systems with Rashba spin-orbit coupling
Edvin G. Idrisov, Eddwi H. Hasdeo, Byjesh N. Radhakrishnan +1
We study a two-dimensional (2D) electron system with a linear spectrum in the presence of Rashba spin-orbit (RSO) coupling in the hydrodynamic regime. We derive a semiclassical Bol…
