Mass-anisotropy driven stripe pattern formation and directional modulational instability in polariton condensate
Hari Sadhan Ghosh, Soumyadeep Halder, Subrata Das +1
Motivated by recent experimental advances toward electrical control of the effective mass and the realization of anisotropic mass distributions, we investigate the impact of mass a…
Response of a dipolar BEC to Laguerre-Gaussian beam driven STIRAP
Deepu Singh, Hari Sadhan Ghosh, Arpana Saboo +2
Coherent light-matter coupling via STIRAP can offer a versatile route to nucleate quantized vortices in Bose-Einstein condensates through the orbital angular momentum transfer from…
Rotation-triggered Kelvin-Helmholtz and counter-superflow instabilities in a three-component Bose-Einstein condensate
Susovan Giri, Arpana Saboo, Hari Sadhan Ghosh +2
Interfacial hydrodynamic instabilities in multicomponent superfluids provide a versatile platform to explore nonequilibrium quantum dynamics beyond classical fluid analogues. We st…
Roadmap to vortex nucleation below critical rotation frequency in a dipolar Bose-Einstein condensate
Soumyadeep Halder, Hari Sadhan Ghosh, Arpana Saboo +2
The formation of quantized vortices in a superfluid above a certain critical trap rotation frequency serves as a hallmark signature of superfluidity. Based on the beyond mean field…
