Proposed Scheme for a Cavity‐Based Quantum Battery

Abstract

A scheme for quantum batteries consisting of an atom‐cavity interacting system under a structured reservoir in the non‐Markovian regime is proposed. A multi‐parameter regime for the cavity‐reservoir coupling and reveal how these parameters affect the performance of the quantum battery is investigated. Specifically, how two distinct types of environments impact the charging process of the quantum battery from a memory perspective is examined. The findings indicate that in a memory‐influenced environment, both the stored energy and the extractable work are higher compared to when the cavity interacts with a memory‐less environment. This proposed scheme is simple and may be achievable for realization and implementation.
