Quantum energy preservation in a moving Heisenberg-ring quantum battery

We propose a physical model of a moving quantum battery composed of Heisenberg XXZ interacting atoms in a leaky cavity. By employing the open quantum system method, we demonstrate the optimized quantum work extraction is enhanced by the battery’s speed, interatomic interactions, and the number of atoms. In a spontaneous discharge process, quantum work extraction will decline to a stable value which can be determined by the number of atoms in the battery. Considering the interaction between the quantum battery and the environment, we explore the Markovian or non-Markovian dynamics of quantum work extraction. Due to the preservation of quantum coherence for moving atoms, the manipulation of motion velocity can substantially improve the energy storage near quantum criticality. It is found out that the motion of multipartite quantum battery contributes to inhibiting spontaneous energy dissipation.
