On quantum trajectories and an approximation to the Wigner path integral

摘要

In this paper we suggest an approximation to the Wigner Path integral using quantum trajectories. We discuss the results in terms of Bohmrsquo;s theory and Takabayasirsquo;s study of the relation between Bohm and Wigner theory. We discuss how this new approach is an approximation to Bohmrsquo;s theory and discuss its validity. We also suggest a method of evaluation and where such an approach would be useful.
