报告题目：Light transport in cold atoms : coherent backscattering and other phenomena 　　报告人：Asso.Prof. David Wilkowski 　　University of Nice Sophia-Antipolis, France 　　时间：2009年10月22日(星期四)上午10：00 　　地点：所办公大楼六楼会议室 　　Abstract: 　　I present some experiments on multiple scattering of light in cold atomics samples. Studying the coherent backscattering effects we have show that the phase coherence of the wave may be preserved even at resonance. We have then study some dephasing processes that I will explain during my talk.
