Calculation of Autocorrelation Functions Using the Wigner Representation of Quantum Mechanics
Document Type
Article
Abstract
A procedure is described for calculating both the magnitude and phase of an autocorrelation function from the Wigner distribution. The method is fully compatible with both quantum and classical-based procedures for propagating the Wigner distribution. Numerical results are presented for an initial Gaussian in a considerably anharmonic Morse potential, showing that the method is accurate for several vibrational periods.
