摘要
利用参量相关的Ｂｏｇｏｌｉｕｂｏｖ变换公式，导出描写Ｐａｕｌ阱系统含时哈密顿的精确本征态——广义ＳＵ（１，１）相干态，讨论了关于这些态的粒子数涨落和平方振幅压缩特性。
The Parameter - dependent formulation of the Bogoliubov transformation is employed to derive exact eigenstates of the time - dependent Hamiltonian describing the Paul trap. It is shown that these states are a sort of generalized SU(1,1 ) coherent states. The fluctuation of the number of the particles and the squeezing character of square amplitude are discussed.
