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…

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…

Observation of topological Phenomena in a Weyl Exceptional Ring with Single Photons
Zhong-Sheng Chen, Wei-Xin Chen, Fan Wu +5
Compared with Hermitian theory, non-Hermitian physics offers a fundamentally different mathematical framework, enabling the observation of topological phenomena that have no analog…
