摘要
The q-p phase-space distribution function is a popular tool to study semiclassical physics and to describe the quantum aspects of a system. In this paper by using the pure state density operator formula of the Husimi operator Delta(h)(q, p; k) = vertical bar p, q >(kk) < p, q vertical bar we deduce the Husimi function of the excited squeezed vacuum state. Then we study the behavior of Husimi distribution graphically.
