Theory Of Interference Of Large Molecules

Abstract

In the experiments with large molecules, the diameter of particles has approached the width of the slits. Therefore, a theoretical description of these cases should include a finite particle size. We are developing a theory of quantum interference which takes into account the trajectories and the size of particles [1,2]. The theory uses a distribution of transverse momenta of particles to describe emergence of an interference pattern during accumulation of single particle arrivals to the screen. In this way we are accomplishing the task which Barut assigned to theoretical physicists by writing: "It now becomes a task of theoretical physics to build models and theories of single events, and a task of experimental physics to record more of single events" [3].
