Title: Twisting the quantum Speaker: Prof. Charles W.

Yet it was only in 1992 that physicists managed to control a basic property of light waves: their ability to swirl about their axis of propagation. During the past 10 years such techniques of control have also been implemented in atoms, electrons and neutrons. I will present a simple description of these phenomena suited for mathematicians, emphasizing basic properties of the wave equation and the role of special functions, and showing how these are applied in our recent work on twisting neutron waves.* *C.
