Accessing and Manipulating Dispersive Shock Waves in a Nonlinear and Nonlocal Rydberg Medium
Chao Hang, Zhengyang Bai, Weibin Li +2
Dispersive shock waves (DSWs) are fascinating wave phenomena occurring in media when nonlinearity overwhelms dispersion (or diffraction). Creating DSWs with low generation power an…
Experimental Observation of Partial Parity-Time Symmetry and Its Phase Transition with a Laser-Driven Cesium Atomic Gas
Yongmei Xue, Chao Hang, Yunhui He +5
Realization and manipulation of parity-time (PT) symmetry in multidimensional systems are highly desirable for exploring nontrivial physics and uncovering exotic phenomena in non-H…
Quantum Reflections of Nonlocal Optical Solitons in a Cold Rydberg Atomic Gas
Zhengyang Bai, Qi Zhang, Guoxiang Huang
Quantum reflection refers to a non-vanishing reflection probability in the absence of a classically turning point. Much attention has been paid to such reflections due to their fun…
Electromagnetically Induced Transparency of Interacting Rydberg Atoms with Two-Body dephasing
Dong Yan, Binbin Wang, Zhengyang Bai +1
We study electromagnetically induced transparency of a ladder type configuration in ultracold atomic gases, where the upper level is an electronically highly excited Rydberg state.…
Stable single light bullets and vortices and their active control in cold Rydberg gases
Zhengyang Bai, Weibin Li, Guoxiang Huang
Realizing single light bullets and vortices that are stable in high dimensions is a long-standing goal in the study of nonlinear optical physics. On the other hand, the storage and…
Storage and Retrieval of Light Pulses in a Fast-Light Medium via Active Raman Gain
Datang Xu, Zhengyang Bai, Guoxiang Huang
We propose a scheme to realize the storage and retrieval of light pulses in a fast-light medium via a mechanism of active Raman gain (ARG). The system under consideration is a four…
Analogue of double--type atomic medium and vector dromions in a plasmonic metamaterial
Qi Zhang, Zhengyang Bai, Guoxiang Huang
We consider an array of the meta-atom consisting of two cut-wires and a split-ring resonator interacting with an electromagnetic field with two polarization components. We prove th…
Storage and retrieval of (3+1)-dimensional weak-light bullets and vortices in a coherent atomic gas
Zhiming Chen, Zhengyang Bai, Hui-jun Li +2
A robust light storage and retrieval (LSR) in high dimensions is highly desirable for light and quantum information processing. However, most schemes on LSR realized up to now enco…
Enhanced third-order and fifth-order Kerr nonlinearities in a cold atomic system via Rydberg-Rydberg interaction
Zhengyang Bai, Guoxiang Huang
We investigate the optical Kerr nonlinearities of an ensemble of cold Rydberg atoms under the condition of electromagnetically induced transparency (EIT). By using an approach beyo…
Ultraslow Optical Solitons and Their Storage and Retrieval in an Ultracold Ladder-Type Atomic System
Yang Chen, Zhengyang Bai, Guoxiang Huang
We propose a scheme to obtain stable nonlinear optical pulses and realize their storage and retrieval in an ultracold ladder-type three-level atomic gas via electromagnetically ind…
