相干态理论在多重激发态中的应用
Application of the coherent state formalism to multiply excited states
摘要：
得到了多个正交相干玻色子粒子构成的相干态之间的m体算符矩阵元的一般表达式。这使得相干态形式主义被应用到拥有任意大数量的内在激发量子的状态。为了说明，将该方法应用于二维振子模型[U（3）模型]，计算了大N极限下所有激发态的能量。
英文摘要：
A general expression is obtained for the matrix element of an m-body operator between coherent states constructed from multiple orthogonal coherent boson species. This allows the coherent state formalism to be applied to states possessing an arbitrarily large number of intrinsic excitation quanta. For illustration, the formalism is applied to the two-dimensional vibron model [U(3) model], to calculate the energies of all excited states in the large-N limit.
