Multiple mobility rings in non-Hermitian Su-Schrieffer-Heeger chain with quasiperiodic potentials
Guan-Qiang Li, Zhi-Yu Lin, You-Jiao Dong +3
The localization property of a non-Hermitian Su-Schrieffer-Heeger (SSH) chain with quasi-periodic on-site potential is investigated. In contrast to the preceding investigations, th…
Optimal control of population transfer in multi-level systems by dynamical quantum geometric tensor
Guan-Qiang Li, Yu-Qi Zhang, Hao Guo +3
The optimal control of population transfer for multi-level systems is investigated from the perspective of quantum geometry. Firstly, the general theoretical framework of optimizin…
A continuous variable quantum battery with wireless and remote charging
Jun Wen, Zheng Wen, Ping Peng +1
Quantum battery has become one of the hot issues at the research frontiers of quantum physics recently. Charging power, extractable work and wireless charging over long-distance ar…
Fast and robust production of quantum superposition states by the fractional shortcut to adiabaticity
Guan-Qiang Li, Hao Guo, Yu-Qi Zhang +2
The fractional shortcut to adiabaticity (f-STA) for production of quantum superposition states is proposed firstly via a three-level system with -type linkage pattern and a fou…
