Comment on “Time-dependent general quantum quadratic Hamiltonian system”
Yujun Zheng · Physical Review A · 2006
It is shown that the propagator and wave function recently found by are not complete and the results are not correct for constant coefficients of a time-dependent general quantum quadratic Hamiltonian for the case of . We presented the correct evolution operator, propagator, and wave function of the general time-dependent quantum quadratic Hamiltonian system.
