布洛赫振子:波包的运动

Bloch Oscillators: motion of wave-packets

Vincenzo Grecchi, Andrea Sacchetti

摘要:

本文综述了在晶体动量表象中布洛赫振子运动的一些已知结果。我们强调,加速定理,通常由大多数作者,是不完整的,但在纯布洛赫状态的情况下。事实上,加速度定理的精确版本应该包含一个相位因子,它取决于时间和晶体动量变量。正如我们所示,这个相位因子起着至关重要的作用,以了解布洛赫振荡器的位置变量的运动。

英文摘要:

In this paper we review some known results on the motion of Bloch Oscillators in the crystal momentum representation. We emphasize that the acceleration theorem, as usually stated by most of the authors, is incomplete, but in the case of pure Bloch states. In fact, the exact version of the acceleration theorem should contain a phase factor depending on both the time and crystal momentum variables. As we show this phase factor plays an essential role in order to understand the motion of Bloch Oscillators in the position variable.
