摘要: 利用费米相干态和正规乘积内的积分法,研究费米体系下两个态的交换算符.得到了交换算符在相干态表象中和粒子数表象中的表示,同时将其推广到在多状态情况下态之间的循环交换.

Abstract: Using the Fermi coherent state and the integration technique of normal- ordered to study exchange operators of the two states in a Fermi system, we obtain the operators in the coherent state representation and the number representation. Furthermore, we generalize the results to the case of several states.

Key words: Fermi operator, coherent state, anti- commutative c- number
