Cold atoms passing through a thin laser beam:a Fourier optics approach
《Chinese Optics Letters》2016年第7期5-9,共5页周蜀渝 钱军 张善超 王育竹 
supported by the National Natural Science Foundation of China under Grant Nos.10804115 and 91336103;the support by the National Natural Science Foundation of China(No.11104292)
A Fourier optics approach can be a concise and powerful tool to solve problems in atom optics. In this report, we adopt it to investigate the kinetic behavior of cold atoms passing through a far red-detuned Gaussian b...

Spin–orbit coupled Bose–Einstein condensates with Rydberg-dressing interaction
《Chinese Physics B》2015年第9期130-134,共5页吕昊 朱少兵 钱军 王育竹 
Project supported by the National Basic Research Program of China(Grant No.2011CB921504);the National Natural Science Foundation of China(Grant No.11104292)
Interaction between Rydberg atoms can be used to control the properties of interatomic interaction in ultracold gases by weakly dressing the atoms with a Rydberg state. Here we investigate the effect of the Rydberg-dr...

研究了存在原子间有效三体相互作用的情况下双阱势场中超冷玻色气体的相位相干性,其中引入无序分布的阱深差来模拟无序势。研究发现,在无序Bose-Hubbard模型中,重整化的三体相互作用能有效增强玻色气体的相位相干性。同时,在强无序势条...

Effects of effective attractive multi-body interaction on quantum phase and transport dynamics of a strongly correlated bosonic gas across the superfluid to Mott insulator transition
《Chinese Physics B》2013年第11期204-210,共7页孙剑芳 崔国栋 姜伯楠 钱军 王育竹 
Project supported by the National Basic Research Program of China(Grant No.2011CB921504);the National Natural Science Foundation of China(Grant No.11104292)
We theoretically investigate quantum phases and transport dynamics of ultracold atoms trapped in an optical lattice in the presence of effective multi-body interaction. When a harmonic external potential is added, sev...

Transport dynamics of an interacting binary Bose Einstein condensate in an incommensurate optical lattice
《Chinese Physics B》2013年第10期140-145,共6页崔国栋 孙剑芳 姜伯楠 钱军 王育竹 
Project supported by the National Natural Science Foundation of China(Grant No.11104292);the National Basic Research Program of China(GrantNo.2011CB921504)
We investigate the transport dynamics of an interacting binary Bose-Einstein condensate in an incommensurate optical lattice and predict a novel splitting of a matter wavepacket induced by disorder potential and inter...

Effects of transverse trapping on the ground state of a cigar-shaped two-component Bose-Einstein condensate
《Chinese Physics B》2013年第9期534-538,共5页崔国栋 孙剑芳 姜伯楠 钱军 王育竹 
supported by the National Natural Science Foundation of China (Grant No. 11104292);the National Basic Research Program of China (Grant No. 2011CB921504)
We derive the coupled nonpolynomial nonlinear Schr6dinger equations for a two-component Bose-Lmstem conaensate in a quasi-one-dimension geometry and investigate the effects of a tightly transverse trapping on the grou...

Magneto optical trap for neutral mercury atoms
《Chinese Physics B》2013年第4期32-35,共4页刘洪力 尹士奇 刘亢亢 钱军 徐震 洪涛 王育竹

Due to its low sensitivity to blackbody radiation, neutral mercury is a good candidate for the most accurate optical lattice clock. Here we report the observation of cold mercury atoms in a magneto-optical trap （MOT...
