AC-STARK SHIFT OF LEVEL IN TWO-LEVEL ATOM UNDER THE INTERACTION OF MONO-MODE QUANTIZED FIELD
单模量子场作用下二能级原子能级的AC Stark移动

By analyzing the phase of transition probability amplitude,a formula for level shift induced by the time-dependent perturbation of quantum transition is given.AC-Stark shifts of the levels in two-level atoms are calculated,which are induced by mono-mode quantized field.The calculated results indicate that the quantum statistic property can directly influence the atomic level shift.
