Atomic Dipole Squeezing and Coherent Population Trapping in the Nonlinear Jaynes-Cummings Model
摘要
本文运用全量子理论研究了与单模光场双光子作用的非线性Jaynes-Cummings模型系统中原子的量子行为，论证了原子发生相干俘获的条件，分别讨论了初场处于真空态(=0)和热混态(≠0)时非线性修正项和双光子失谐量对原子布居反转的演化特性和偶极压缩效应的影响.
Abstract
The atomic quantumbehavior in the interaction system of a single-mode light field with the nonlinearJaynes-Cummings model via two-photon processes are studied by means of quantum theory. Thecondition for taking place of the phenomenon of coherent trapping is given.The influencesof the nonlinear correction term and the two-photon frequency detuning on the timeevolution of atomic particle number population inversion and the atomic dipole squeezingare discussed,respectively,when the initial field is on the vacuum state (= 0) and on the thermalchaotic state (≠ 0).
