| 英文摘要 | Taking into account the off-diagonal matrix elements of the position operator, the motion of Bloch electrons in a one-dimensional lattice under the action of an arbitrary time-dependent electric field is investigated. The exact solutions for the evolution amplitudes and the mean-square displacement are obtained in the case of a one-band approximation. The evolution behavior of Bloch electrons in several types of electric fields is discussed. It has been found that the off-diagonal matrix elements of the position operator only quantitatively affect the dynamic localization and delocalization of Bloch electrons previously obtained without considering this effect. |
