摘      要：Quantum dynamics of a charged particle in a two-dimensional （2D） lattice subject to magnetic and electric fields is a rather complicated interplay between cyclotron oscillations （the case of vanishing electric field） and Bloch oscillations （zero magnetic field）, details of which has not yet been com- pletely understood. In the present work we suggest to study this problem by using cold atoms in optical lattices. We introduce a one-dimensional （1D） model which can be easily realized in labora- tory experiments with quasi-lD optical lattices and show that this model captures many features of the cyclotron-Bloch dynamics of the quantum particle in 2D square lattices.
