Hybrid Quasi-Bound State in the Continuum at Topological Quantum Optics Interface
Yue-Zhi Zhang, Leong-Chuan Kwek, Wei Nie
Topological manipulation of light provides a versatile toolbox for photonic technologies. Here, we show that a topological atom array can induce photon localization in a waveguide…

Light Manipulation via Tunable Collective Quantum States in Waveguide-Coupled Bragg and Anti-Bragg Superatoms
Zhengqi Niu, Wei Nie, Daqiang Bao +8
A many-body quantum system which consists of collective quantum states, such as superradiant and subradiant states, behaves as a multi-level superatom in light-matter interaction.…

Collectively induced transparency and absorption in waveguide QED with Bragg atom arrays
Haolei Cheng, Wei Nie
Collective quantum states, such as subradiant and superradiant states, are useful for controlling optical responses in many-body quantum systems. In this work, we study novel colle…
