本文引进自旋体系的一般SU(2)相干态,讨论它的压缩特性、反聚束特性及其产生。证明当SU(2)群收缩到谐振子群时,一般SU(2)相干态转变成一般Glauber相干态,并给出有关的收缩结果。This paper introduces the generalized SU(2) coherent state of spin system. Its squee ing and antibunching, and generation are discussed. It is shown that under the contraction of group SU(2) to the harmonic-oscillator group, the generalized SU(2) coherent state transforms to the generalized Glauber coherent state, the related results of the contraction are also given.
