Single-photon scattering by a giant molecule asymmetrically coupled to parallel waveguides
Ze-Quan Zhang, Guang-Zheng Ye, Wei-Xin Chen +2
We investigate single-photon scattering in a waveguide-QED setup, where a giant molecule composed of two frequency-detuned giant atoms is coupled to two parallel waveguides via mul…

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…
