Topological sensing of superfluid rotation using non-Hermitian optical dimers
Aritra Ghosh, Nilamoni Daloi, M. Bhattacharya
We theoretically investigate a non-Hermitian optical dimer whose parameters are renormalized by dispersive and dissipative backaction from the coupling of the passive cavity with a…
Supersolid Rotation in an Annular Bose-Einstein Condensate coupled to a Ring Cavity
Gunjan Yadav, Nilamoni Daloi, Pardeep Kumar +2
We theoretically investigate an annularly confined Bose-Einstein Condensate (BEC) coupled to a four-mirror ring cavity supporting traveling-wave optical modes. Under symmetric driv…
Atomic-superfluid heat engines controlled by twisted light
Aritra Ghosh, Nilamoni Daloi, M. Bhattacharya
We theoretically propose a quantum heat engine using a setup consisting of a ring-trapped Bose-Einstein condensate placed in a Fabry-Pérot cavity where the optical field carries o…
Cavity Optomechanical Quantum Memory for Twisted Photons Using a Ring BEC
Nilamoni Daloi, Rahul Gupta, Aritra Ghosh +3
We theoretically propose a photonic orbital angular momentum (OAM) quantum memory platform based on an atomic Bose-Einstein condensate confined in a ring trap and placed inside a F…
