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…

Dynamical signatures of superfluidity and shear rigidity in different phases of a dipolar Bose-Einstein condensate
Soumyadeep Halder, Hari Sadhan Ghosh, Axel Pelster +1
We show that a sudden change in the polarization direction of the magnetic dipole moments of the atoms in a dipolar Bose-Einstein condensate (BEC) can serve as a useful dynamical p…
