PT-symmetric coupler with a coupling defect: soliton interaction with exceptional point
Yuli V. Bludov, Chao Hang, Guoxiang Huang +1
We study interaction of a soliton in a parity-time (PT) symmetric coupler which has local perturbation of the coupling constant. Such a defect does not change the PT-symmetry of th…
Guiding ultraslow weak-light bullets with Airy beams in a coherent atomic system
Chao Hang, Guoxiang Huang
We investigate the possibility of guiding stable ultraslow weak-light bullets by using Airy beams in a cold, lifetime-broadened four-level atomic system via electromagnetically ind…
Ultraslow Helical Optical Bullets and Their Acceleration in Magneto-Optically Controlled Coherent Atomic Media
Chao Hang, Guoxiang Huang
We propose a scheme to produce ultraslow (3+1)-dimensional helical optical solitons, alias helical optical bullets, in a resonant three-level -type atomic system via quantum coh…
Slow-light Airy wave packets and their active control via electromagnetically induced transparency
Chao Hang, Guoxiang Huang
We propose a scheme to generate (3+1)-dimensional slow-light Airy wave packets in a resonant -type three-level atomic gas via electromagnetically induced transparency. We show t…
