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…
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…
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…
Sensing atomic superfluid rotation beyond the standard quantum limit
Rahul Gupta, Pardeep Kumar, Rina Kanamoto +2
Atomic superfluids formed using Bose-Einstein condensates (BECs) in a ring trap are currently being investigated in the context of superfluid hydrodynamics, quantum sensing and mat…
Hybrid Rotational Cavity Optomechanics Using Atomic Superfluid in a Ring
Sanket Das, Pardeep Kumar, M. Bhattacharya +1
We introduce a hybrid optomechanical system containing an annularly trapped Bose-Einstein condensate (BEC) inside an optical cavity driven by Lauguerre-Gaussian (LG) modes. Spiral…
