Quadratic power enhancement in extended Dicke quantum battery
Harsh Sharma, Himadri Shekhar Dhar
We demonstrate a quadratic enhancement of power in a battery consisting of two-level systems or spins interacting with two photonic cavity modes, where one of the modes is in t…
Thermodynamic Probes of Multipartite Entanglement in Strongly Interacting Quantum Systems
Harsh Sharma, Sampriti Saha, A. S. Majumdar +2
Quantifying multipartite entanglement in quantum many-body systems and hybrid quantum computing architectures is a fundamental yet challenging task. In recent years, thermodynamic…
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…
