Abstract:
Quantum systems are generally described theoretically using wave mechanics developed by Schrödinger. In the hydrodynamic formulation of quantum mechanics, Schrödinger’s equation is replaced by real nonlinear differential equations which describe the flow of probability. This hydrodynamic picture is especial useful for describing recent experimental results showing electron vortices, akin to vortices in fluids. These recent experiments involving electron-atom collisions, ion-atom collisions, and Bose-Einstein condensates will be discussed. Additionally, an experiment which searches for these vortices in positron-hydrogen collisions will be proposed.
