Revisiting Bloch oscillations in homogeneous and binary chains from an exact quantum mechanical perspective

We present an exact analytic approach to study Bloch oscillations which allows to study cases where the semiclassical arguments are not valid. The method is focused on the velocity operator V. Two representative examples are addressed here: (i) the superposition of AC and DC electric fields in a one...
