Cavity-Driven Multispectral Gain for High-Sensitivity NV Center Magnetometers
Himanshu Kumar, Rahul Gupta, Saikat Ghosh +2
We report a cavity-enabled solid-state magnetometer based on an NV ensemble coupled with a dielectric cavity, achieving 12 pT/ sensitivity and a nearly threefold ga…
Macroscopic entanglement between localized domain walls inside a cavity
Rahul Gupta, H. Y. Yuan, Himadri Shekhar Dhar
We present a scheme for generating stable and tunable entanglement between two localized Bloch domain walls in nanomagnetic strips kept inside a chiral optical cavity. The entangle…
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…
