Antibunched photon-pair source based on photon blockade effect in a nondegenerate optical parametric oscillator
Yi Ren, Shouhui Duan, Wenzhi Xie +2
Nonclassical light sources, such as correlated photon-pairs, play an important role in quantum optics and quantum information processing systems. This study proposes a process to g…
Photon blockade in a bi-mode nonlinear nano-cavity embedded with a quantum-dot
Xinyun Liang, Zhenglu Duan, Qin Guo +3
We study the interaction between a quantum-dot and a bi-mode micro/nano-optical cavity composed of second-order nonlinear materials. Compared with the Jaynes-Cummings (J-C) model,…
Conventional and unconventional photon blockade effects in an atom-cavity system
Xinyun Liang, Zhenglu Duan, Qin Guo +3
A two-level system interacting with a cavity field is an important model for investigating the photon blockade (PB) effect. Most work on this topic has been based on the assumption…
Pulse-regulated single-photon generation via quantum interference in a nonlinear nanocavity
Yuyi Yan, Yanbei Cheng, Shengguo Guan +2
A scalable on-chip single-photon source at telecommunications wavelengths is an essential component of quantum communication networks. In this work, we numerically construct a puls…
Phonon antibunching effect in coupled nonlinear micro/nanomechanical resonator at finite temperature
Shengguo Guan, Warwick Bowen, Cunjin Liu +1
In this study, we investigate the phonon antibunching effect in a coupled nonlinear micro/nanoelectromechanical system (MEMS/NEMS) resonator at a finite temperature. In the weak dr…
Induced transparency in optomechanically coupled resonators
Zhenglu Duan, Bixuan Fan, Thomas M. Stace +2
In this work we theoretically investigate a hybrid system of two optomechanically coupled resonators, which exhibits induced transparency. This is realized by coupling an optical r…
Improving entanglement of even entangled coherent states by a coherent superposition of photon subtraction and addition
Shi-You Liu, Jie-Hui Huang, Li-Yun Hu +3
A new entangled quantum state is introduced by applying local coherent superposition (ra^+ +ta) of photon subtraction and addition to each mode of even entangled coherent state (EE…
Goos-Hanchen-like shift of three-level matter wave incident on Raman beams
Zhenglu Duan, Liyun Hu, XueXiang Xu +1
When a three-level atomic wavepacket is obliquely incident on a "edium slab" consisting of two far-detuned laser beams, there exists lateral shift between reflection and incident p…
Slowing light with a coupled optomechanical crystal array
Zhenglu Duan, Bixuan Fan
We study the propagation of light in a resonator optical waveguide consisting of evanescently coupled optomechanical crystal array. In the strong driving limit, the Hamiltonian of…
The focusing effect of cold atomic cloud with a red-detuned Gaussian beam
Zhenglu Duan, Shuyu Zhou, Tao Hong +1
We have demonstrated an atom-optical lens, with the advantage of a small scale and flexible adjustment of the parameters, realized by a far red-detuned Gaussian laser beam perpendi…
Wigner function evolution in self-Kerr Medium derived by Entangled state representation
Li-yun Hu, Zheng-lu Duan, Xue-xiang Xu +1
By introducing the thermo entangled state representation, we convert the calculation of Wigner function (WF) of density operator to an overlap between "two pure" states in a two-mo…
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…
Goos-Hänchen-Like Shifts in Atom Optics
Jianhua Huang, Zhenglu Duan, Hong Y. Ling +1
We consider the propagation of a matter wavepacket of two-level atoms through a square potential created by a super-Gaussian laser beam. We explore the matter wave analog of Goos-H…
