A puzzle in quantum dynamics
C. Y. Chen
The textbook treatment in that the wave function of a dynamical system is expanded in an eigenfunction series is investigated. With help of an elementary example and some mathemati…

General procedure of solving the time-dependent Schrödinger equation
C. Y. Chen
A nonperturbative procedure of solving the time-dependent Schrödinger equation, called the multi-projection approach or phase dynamics of quantum mechanics, is derived and illustra…

Time-dependent Perturbation Theory in Quantum Mechanics
C. Y. Chen
After revealing difficulties of the standard time-dependent perturbation theory in quantum mechanics mainly from the viewpoint of practical calculation, we propose a new quasi-cano…
