Phenomenon of Backflow


Backflow is a counterintuitive phenomenon discovered first in quantum mechanics. However I will show that, contrary to the statements made by many authors, the backflow is not a nonclassical effect. The backflow is a characteristic feature of solutions of the wave equations: quantum and classical. I will present simple solutions of the Maxwell equations and the Dirac equation where the backflow phenomenon is clearly seen. I will describe backflow in relativistic theories but this phenomenon can occur in the solutions of all kinds of wave equations: quantum and classical. I believe that it can be seen even in water waves on a pond.
