测量玻色-爱因斯坦凝聚体光致非线性的干涉方案

Interference scheme to measure light-induced nonlinearities in Bose-Einstein condensates

K. V. Krutitsky, K. -P. Marzlin, J. Audretsch

摘要:

Gross-Pitaevskii方程中的光致非线性项来自于两个原子之间的光子的受激相干交换。对于光学偶极阱中的原子,这种效应取决于俘获激光束的空间分布。两种不同的激光束可以诱导相同的陷阱势,但非常不同的非线性。我们提出了一个计划来测量光致非线性,这是基于这一观察。

英文摘要:

Light-induced nonlinear terms in the Gross-Pitaevskii equation arise from the stimulated coherent exchange of photons between two atoms. For atoms in an optical dipole trap this effect depends on the spatial profile of the trapping laser beam. Two different laser beams can induce the same trapping potential but very different nonlinearities. We propose a scheme to measure light-induced nonlinearities which is based on this observation.
