摘要: We present a quantum battery model comprising two lossless cavities that interact through a controlled photon-hopping mechanism, each housing an isolated two-level atom. This study explores the possibility of influencing the interaction between cavities within the traditional two single-cavity working modes, thereby paving the way for enhanced charging performance. By solving the generalized double Jaynes-Cummings model with cavity-cavity interactions, we demonstrate the positive impact of such interactions on battery charging, enabling the quantum battery to outperform the single-cavity case in terms of charging time and average charging power. Additionally, we investigate the influence of different cavity-cavity interaction strengths on charging efficiency and attempt to explain the underlying mechanisms by analyzing the entanglement within the system.
