摘要：The technique of two-dimensional Fourier-transform (2DFT) spectroscopy was originally developed in NMR and implemented in optical region in recent years. Since then, optical 2DFT spectroscopy has developed into a major tool to study the interactions and dynamics in various quantum systems. In this talk, I will present the experimental implementation of this technique with a new-built apparatus and some recent results on the study of the coherent optical response of potassium vapor. In addition, the application of 2DFT spectroscopy in other quantum systems is demonstrated.
个人简介：Xingcan Dai is an Assistant Professor in the Department of Physics at Tsinghua University of China. Dr. Dai received his B.S. and M.S. degrees in Physics from Tsinghua University of China, in 1997 and 2000, respectively, and his Ph.D. degree in Physics from the University of California at Berkeley in 2006. He was a Research Associate in the group of Professor Steven T. Cundiff at the Joint Institute for Laboratory Astrophysics (JILA) between 2007 and 2010. Working with his colleagues in JILA, he built a multidimensional optical nonlinear spectrometer. The apparatus has been used to study the multi-dimensional spectroscopy of nanostructures and dense atomic vapors. He became a tenure-track assistant professor in the Department of Physics at Tsinghua University in March 2010. His current research interests center around the optical spectroscopy of nanostructures and alkali dimers.
