Laser stabilization to an atomic transition using an optically generated dispersive lineshape
Laser stabilization atomic transition optically generated dispersive lineshape Atomic Physics
2012/4/19
We report on a simple and robust technique to generate a dispersive signal which serves as an error signal to electronically stabilize a monomode cw laser emitting around an atomic resonance. We explo...
基于考虑了氢同位素效应的DTO(1A1)分子的多体展式分析势能函数, 用准经典的Monte-Carlo 轨迹法研究了O+DT (0,0)体系的分子反应动力学过程. 结果表明, 在碰撞能较低时(<209.20 kJ/mol), 可以生成长寿命DTO(1A1) 络合物, 并且该络合反应是有阈能反应, 这一结论与用多体项展式理论计算的DTO分子势能曲线结果一致. 随碰撞能增加, 逐渐出现置换产物OT 和...

Modeling core-hole screening jellium clusters density functional theory
2012/2/28
The screening of a 2p core-hole in Na clusters is investigated using density functional theory applied to an extended jellium model with an all-electron atom in the center. The study is related to rec...

Observation rotational transition trapped sympathetically cooled molecular ions
2012/2/28
We demonstrate rotational excitation of molecular ions that are sympathetically cooled by laser-cooled atomic ions to a temperature as low as ca. 10 mK. The molecular hydrogen ions HD+ and the fundame...

Brief remarks Electric dipole moment enhancement factor thallium
2012/2/28
In a recent paper by Porsev et al. [arXiv:1201.5615v1], the authors have claimed to have resolved the controversy arising from the different ab initio results available for the EDM enhancement factor ...
Analogy of RKKY oscillations to the heat exchange in cold atoms
Analogy RKKY oscillations the heat exchange cold atoms
2012/2/28
An oscillatory term is found in both the energy expectation and dynamics of a wave-packet in a time-varying harmonic trap and infinite potential well. They are proved to oscillate in coherence with th...

Guiding Rydberg atoms high-gradient magnetic guide
2012/2/28
We study the guiding of $^{87}$Rb 59D$_{5/2}$ Rydberg atoms in a linear, high-gradient, two-wire magnetic guide. Time delayed microwave ionization and ion detection are used to probe the Rydberg atom ...
Over the past few years we have built an apparatus to demonstrate the entanglement of neutral Rb atoms at optically resolvable distances using the strong interactions between Rydberg atoms. Here we re...
