Exact quantum theory of a time-dependent bound quadratic Hamiltonian system
Kyu Hwang Yeon, Kang Ku Lee, Chung‐In Um +2 more
Using the path-integral method, the propagator, the wave function, and the expectation values are evaluated explicitly for a time-dependent bound quadratic Hamiltonian system. We also have derived the relation between the wave function and a dynamical invariant which determines whether or not the system is bound. The expectation value of the quantum-mechanical invariant obeys the uncertainty relation with an auxiliary condition as the solution of the classical equation of the system.
