Quantum information with conserved quantities
Jing Liu, Jing Cheng, Li-Bin Fu +1
Conserved quantities are crucial in quantum physics. Here we discuss a general scenario of Hamiltonians. All the Hamiltonians within this scenario share a common conserved quantity…
Quantum tunneling time of a Bose-Einstein condensate traversing through a laser-induced potential barrier
Zhenglu Duan, Bixuan Fan, Chun-Hua Yuan +3
We theoretically study the effect of atomic nonlinearity on the tunneling time in the case of an atomic Bose-Einstein condensate (BEC) traversing the laser-induced potential barrie…
Quantum superchemistry in an output coupler of coherent matter waves
Hui Jing, Jing Cheng
We investigate the quantum superchemistry or Bose-enhanced atom-molecule conversions in a coherent output coupler of matter waves, as a simple generalization of the two-color photo…
Fourier Analysis of Ghost Imaging
Honglin Liu, Jing Cheng, Yanfeng Bai +1
Fourier analysis of ghost imaging (FAGI) is proposed in this paper to analyze the properties of ghost imaging with thermal light sources. This new theory is compatible with the gen…
Lensless Fourier-Transform Ghost Imaging with Classical Incoherent Light
Minghui Zhang, Qing Wei, Xia Shen +4
The Fourier-Transform ghost imaging of both amplitude-only and pure-phase objects was experimentally observed with classical incoherent light at Fresnel distance by a new lensless…
Transverse localization and slow propagation of light
Jing Cheng, ShenSheng Han, YiJing Yan
The effect of finite control beam on the transverse spatial profile of the slow light propagation in an electromagnetically induced transparency medium is studied. We arrive at a g…
