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…

Protecting information in a parametrically driven hybrid quantum system
Siddharth Tiwary, Harsh Sharma, Himadri Shekhar Dhar
The transfer and storage of quantum information in a hybrid quantum system, consisting of an ensemble of atoms or spins interacting with a cavity, is adversely affected by the inho…
