Evaluation of the Feynman Propagator by Means of the Quantum Hamilton-Jacobi Equation
It is shown that the complex phase of the Feynman propagator is a solution of the quantum Hamilton–Jacobi equation, namely, it is the quantum Hamilton's principal function (or quantum action). Therefore, the Feynman propagator can be computed either by means of the path integration, or by the w...
