Y. Benaryeh et H. Zoubi, THE TIME DEVELOPMENT OPERATORS FOR WIGNER FUNCTIONS OF HARMONIC-OSCILLATORS WITH QUADRATIC HAMILTONIANS, Quantum and semiclassical optics, 8(6), 1996, pp. 1097-1101
Analytical expressions for the time development operators for Wigner f
unctions of harmonic oscillators with quadratic Hamiltonians are devel
oped by the use of group theoretical methods.
