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…
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…
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…
Proposals for realizing a Josephson diode in Atomtronic circuits
Nalinikanta Pradhan, Rina Kanamoto, M. Bhattacharya +1
The Josephson diode, a non-reciprocal quantum element analogous to the familiar semiconductor p-n junction diode, has been realized in solid-state systems but remains unexplored in…
Fractional Shapiro steps in a Cavity-Coupled Josephson ring condensate
Nalinikanta Pradhan, Rina Kanamoto, M. Bhattacharya +1
The Josephson effect presents a fundamental example of macroscopic quantum coherence as well as a crucial enabler for metrology (e.g. voltage standard), sensing (e.g. Superconducti…
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…
