Аннотация: The quantum and classical dynamics in a two-dimensional (2D) periodic potential influenced by a constant force is discussed and compared. Classically, the dynamics is chaotic. A branched flow of the particles similar but more structured than the coherent branched flow in a 2D electron gas is observed. In the classical case, the forПоказать полностьюmation of separate decay channels is explained by dynamical trapping. The quantum dynamics closely follows the classical one. 5555 2002 The American Physical Society.
