| 中文摘要 | Dynamics and energy spectrum of Bloch electron on coupled chains under the action of both a uniform magnetic and an electric field are investigated. The results show that in the general case the energy spectrum of the system is that of two interspaced Wannier-Stark ladders. For the general coupling between chains, explicit solutions for the energy spectrum are obtained, from which the coherent evolution of the band electron is found to be tuned periodically by the ratio of the flux passing through a unit cell to the flux quantum. We also find that the localization effect depends on the coupling strength between chains, the ratio of the hopping matrix element between the nearest-neighbor sites and the static field magnitude.
