标题： Action-Angle Variables for Complex Projective Space and Semiclassical Exactness

摘要： 我们构造了定义在复射影相空间上的经典可积模型的作用量-角度变量，并利用驻相近似法在相干态路径积分表示下计算量子力学传播子。我们证明由此得到的传播子表达式与通过求解含时薛定谔方程所得的精确传播子一致。 显示英文摘要

摘要： We construct the action-angle variables of a classical integrable model defined on complex projective phase space and calculate the quantum mechanical propagator in the coherent state path integral representation using the stationary phase approximation. We show that the resulting expression for the propagator coincides with the exact propagator which was obtained by solving the time-dependent Schr\"odinger equation.
