Quantum phase transitions of the Cavity Heisenberg spin-chain
Lv-Ting Gong, Shao-Fan He, Fu-Quan Dou
The interplay between quantum criticality and ergodicity breaking constitutes a central challenge in complex quantum many-body systems. Here, we investigate ground-state quantum ph…
Shortcuts to adiabaticity in five-level systems using counter-diabatic driving and time-rescaling optimization
Jiahui Zhang, Wenyuan Wang, Fuquan Dou
Shortcuts to adiabaticity (STA) is a common protocol to realize high-fidelity and robust quantum control in various quantum systems. To date, STA has been widely applied in two- an…
Towards a nuclear isomer quantum battery
Ying-Bo Gao, Fu-Quan Dou
Quantum batteries (QBs) -- quantum devices governed by the principles of quantum mechanics -- hold great promise for next-generation energy storage. However, most existing research…
Quantum battery optimized by parametric amplification
Fang-Mei Yang, Jun-Hong An, Fu-Quan Dou
The parametric amplification enabled by two-photon driving constitutes a versatile platform for advanced quantum technologies. We present an optimized scheme for implementing quant…
Ergotropy in Quantum Batteries
Cheng-Jie Wang, Fu-Quan Dou
Ergotropy--a key figure of merit for quantum battery (QB) performance--plays a crucial role. However, the dynamics and physical mechanisms governing ergotropy evolution remain open…
Wireless energy transfer in non-Hermitian quantum battery
Fang-Mei Yang, Fu-Quan Dou
The extraction of energy is one of fundamental challenges in realizing quantum batteries (QBs). Here, we propose two wireless transfer schemes with parity-time symmetries to effici…
