Nonlinear Topological Edge States in a non-Hermitian Array of Optical Waveguides Embedded in an Atomic Gas
Chao Hang, Dmitry A. Zezyulin, Guoxiang Huang +1
We propose a scheme comprising an array of anisotropic optical waveguides, embedded in a gas of cold atoms, which can be tuned from a Hermitian to an odd-PT -- symmetric configurat…
Soliton Diffusion as a Signature of Hawking Radiation in Bose-Einstein Condensates
Chao Hang, Gregory Gabadadze, Guoxiang Huang
We propose a scheme to detect analog Hawking radiation (HR) in an atomic Bose-Einstein condensate (BEC) through measuring the diffusion of a dark soliton. The HR is generated by ch…
Three-Way Entanglement and Three-Qubit Phase Gate Based on a Coherent Six-Level Atomic System
Chao Hang, Yun Li, Lei Ma +1
We analyze the nonlinear optical response of a six-level atomic system under a configuration of electromagnetically induced transparency. The giant fifth-order nonlinearity generat…
Controllable Entanglement of Lights in a Five-Level System
Yun Li, Chao Hang, Lei Ma +1
We analyze the nonlinear optical response of a five-level system under a novel configuration of electro-magnetically induced transparency. We show that a giant Kerr nonlinearity wi…
