Dissipative Quantum Battery in the Ultrastrong Coupling Regime Between Two Oscillators
Yu-qiang Liu, Yi-jia Yang, Zheng Liu +6
In this work, we propose an open quantum battery that stores and releases energy by employing a two-mode ultrastrongly coupled bosonic system, with one mode (the charger) coupled t…

Two-Polariton Blockade via Ultrastrong Light-Matter Coupling
Ting-Ting Ma, Jian Tang, Yun-Lan Zuo +3
We demonstrate that a two-polariton blockade (2PB) can occur under resonant single-polariton driving in an atom-cavity system operating in the ultrastrong coupling (USC) regime-a p…

Behavior of quantum coherence in the ultrastrong and deep strong coupling regimes of light-matter system
Yu-qiang Liu, Qiulin Long, Yi-jia Yang +12
The ultrastrong and deep strong coupling regimes exhibit a variety of intriguing physical phenomena. In this work, we utilize the Hopfield model of a two-mode bosonic system, with…
