摘要：
The U -> +infinity one-dimensional Hubbard model in electric field has been exactly solved. The exact time-evolution states have been obtained, with which we have calculated the charge current exactly. We find that the charge current, despite the strong correlation interactions of electrons, can show undamped Bloch oscillations strangely, which has been further revealed to be mainly due to the temporal periodicity of the Hamiltonian in electric field.
