Stable collective charging of ultracold-atom quantum batteries
Year: 2024
Type: article
Abstract: We propose a quantum battery realized with a few interacting particles in a three-well system with different on-site energies, which could be realized with ultracold-atom platforms. We prepare the initial state in the lowest-energy well and charge the battery using a spatial-adiabatic-passage--based protocol, enabling the population of a higher-energy well. We examine the charging under varying interaction strengths and reveal that the consideration of collective charging results in an intriguing oscillatory behavior of the final charge for finite interactions, through diabatic evolution. Our findings provide an opportunity for building stable and controllable quantum batteries.
