Interference-induced enhancement of field entanglement in a microwave-driven V-type single-atom laser
Wen-Xing Yang, Ai-Xi Chen, Ting-Ting Zha +2
We investigate the generation and the evolution of two-mode continuous-variable (CV) entanglement from system of a microwave-driven V-type atom in a quantum beat laser. By taking i…
Tunneling-assisted optical information storage with lattice polariton solitons in cavity-QED arrays
E. S. Sedov, A. P. Alodjants, S. M. Arakelian +4
Considering two-level media in the array of weakly coupled nano-cavities, we reveal a variety of dynamical regimes, such as diffusion, self-trapping, soliton, and breathers for the…
Massless Dirac Fermions in a Square Optical Lattice
Jing-Min Hou, Wen-Xing Yang, Xiong-Jun Liu
We propose a novel scheme to simulate and observe massless Dirac fermions with cold atoms in a square optical lattice. A U(1) adiabatic phase is created by two laser beams for the…
Suppression of absorption by quantum interference in intersubband transitions of tunnel-coupled double quantum wells
Wen-Xing Yang, Jin Xu, Ray-Kuang Lee
We propose and analyze an efficient scheme for suppressing the absorption of a weak probe field based on intersubband transitions in a four-level asymmetric coupled-quantum well (C…
Slow optical solitons via intersubband transitions in a semiconductor quantum well
Wen-Xing Yang, Ray-Kuang Lee
We show the formation of bright and dark slow optical solitons based on intersubband transitions in a semiconductor quantum well (SQW). Using the coupled Schrodinger-Maxwell approa…
Giant Kerr nonlinearities and slow optical solitons in coupled double quantum-wells
Wen-Xing Yang, Ray-Kuang Lee
We show the formation of slow optical solitons in the asymmetric coupled double quantum-wells (CQW) via a two-photon Raman resonance. With the consideration of real parameters in A…
