Multicritical dissipative phase transitions manipulated by dipole--dipole interactions
Jia-Xin Wang, Qian Bin, Jing-Jing Cao +1
Precise control of criticality in superradiant phase transitions is essential for quantum state engineering and the simulation of nonequilibrium phase transitions. Here, we investi…
Exceptional Point Superradiant Lasing with Ultranarrow Linewidth
Min Du, Qian Bin, Qing-Yang Qiu +2
Achieving superradiant lasing with an ultranarrow linewidth is crucial for enhancing atomic clock stability in quantum precision measurement. By employing the exceptional point (EP…
Cavity QED based on strongly localized modes: exponentially enhancing single-atom cooperativity
Qian Bin, Ying Wu, Jin-Hua Gao +3
Large single-atom cooperativity in quantum systems is important for quantum information processing. Here, we propose to exponentially enhance the single-atom cooperativity paramete…
Topological Quantum Batteries
Zhi-Guang Lu, Guoqing Tian, Xin-You Lü +1
We propose an innovative design for quantum batteries (QBs) that involves coupling two-level systems to a topological photonic waveguide. Employing the resolvent method, we analyti…
Chiral Interaction Induced Near-Perfect Photon Blockade
Zhi-Guang Lu, Ying Wu, Xin-You Lü
Based on the scattering matrix method, we theoretically demonstrate that the chiral interaction can induce the almost perfect photon blockade (PB) in the waveguide-cavity quantum e…
Floquet Engineering and Harnessing Giant Atoms in Frequency-Comb Emission and Bichromatic Correlations in Waveguide QED
Qing-Yang Qiu, Li-Li Zheng, Ying Wu +1
The capability to design spectrally controlled photon emission is not only fundamentally interesting for understanding frequency-encoded light-matter interactions, but also is esse…
