Non-Markovian renormalization of optomechanical exceptional points
Aritra Ghosh, M. Bhattacharya
The paper studies how memory effects from a non‑Markovian mechanical environment shift the location of exceptional points in driven optomechanical systems and alter observable sign…
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…
Modeling the non-Markovian Brownian motion of an optomechanical resonator
Aritra Ghosh, Malay Bandyopadhyay, M. Bhattacharya
We propose a representative, globally-admissible phenomenological spectral density of the bath for the non-Markovian Brownian motion of an optomechanical resonator, motivated by th…
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…
