Dual-cavity controllable quantum battery

Year: 2024

Type: preprint

Abstract: With the rapid development of quantum science and technology, quantum batteries have also emerged. However, there are still many unresolved issues in the field of quantum batteries. For example, how to improve battery space utilization, maximize battery energy storage, and how to increase and control the charging power of quantum batteries. A major challenge is how to achieve better charging power without reducing the energy storage of the quantum batteries. Here, we propose a controllable dual-cavity quantum battery which can increase the charging power without diminishing capacity of the quantum batteries by manipulating the number of atoms . This control method can effectively adjust the charging power of quantum batteries from $N^2$ times to $N^2.5$ times, and even to $N^3$ times. By adjusting the number of atoms, quantum batteries can achieve theoretical "fast charging" and "slow charging".
