Path integration of the harmonic oscillator with a twotime quadratic action
Abstract
Path integration of the harmonic oscillator with a twotime quadratic action characterizing memory effects is given in terms of the solutions of some integrodifferential equations. The exact propagator in closed form is then obtained for the specific kernel introduced by Feynman in the polaron problem.
