Sensing weak anharmonicities with a passive-active anti-PT symmetric system
Ya-Wei Zeng, Wei-Xin Chen, Tian-Le Yang +2
We propose a scheme for enhanced sensing of weak anharmonicities based on a three-mode anti-parity-time (anti-PT) symmetric cavity-magnon-waveguide system. By tuning the optical ga…

Enhanced charging power in nonreciprocal quantum battery by reservoir engineering
Qi-Yin Lin, Guang-Zheng Ye, Can Li +2
We propose a scheme to achieve a nonreciprocal quantum battery (QB) in the non-Hermitian (NH) system, which can overcome the intrinsic dissipation and reverse flow constraints. The…

Routing thermal noise flow and ground-state cooling in an optomechanical plaquette
Guang-Zheng Ye, Tian-Le Yang, Wan-Jun Su +2
We propose an effective method for cooling two non-degenerate mechanical resonators by routing thermal noise flow in a four-mode optomechanical plaquette. The thermal noise flow be…
