Selective high-order topological states and tunable chiral emission in atomic metasurfaces
Yi-Xin Wang, Yan Zhang, Lei Du +2
Atomic metasurfaces (AMs) provide a powerful nanophotonic platform for integrating topological effects into quantum many-body systems. In this Letter, we investigate the quantum op…

Chirality, Nonreciprocity and Symmetries for a Giant Atom
Luting Xu, Lingzhen Guo
Chiral and nonreciprocal quantum devices are crucial for signal routing and processing in a quantum network. In this work, we study the chirality and nonreciprocity of a giant atom…

Quantum dissipative dynamics of driven Duffing oscillator near attractors
Wei Feng, Lingzhen Guo
We investigate the quantum dissipative dynamics near the stable states (attractors) of a driven Duffing oscillator. A refined perturbation theory that can treat two perturbative pa…
