Spectroscopy of Cold Atoms

将利用非线性光谱学(包括连续波和脉冲光谱学)，寻求更好地理解辐射与冷原子蒸气和BEC的相互作用。在连续波光谱中，将研究冷蒸汽中的碰撞效应以及BEC中的平均场移动和散射，作为两个场之间的频率差的函数。我们将计算由反冲引起的共振的频谱。对于脉冲场相互作用，我们将同时研究脉冲和布拉格散射极限。

Improved understanding of the interaction of radiation with cold atomic vapors and BEC's will be sought, using nonlinear spectroscopy (both continuous wave and pulsed). In cw spectroscopy collisional effects in cold vapors and mean field shifts and scattering in BECs will be studied as a function of the frequency difference between two fields. The spectrum of recoil-induced resonances will be calculated. For pulsed field interactions both the impulse and Bragg scattering limits will be studied.
