Abstract
We study the zitterbewegung of electronic wave packets in III-V zinc-blende semiconductor quantum wells due to spin-orbit coupling. Our results suggest a direct experimental proof of this fundamental effect, confirming a long-standing theoretical prediction. For electron motion in a harmonic quantum wire, we numerically and analytically find a resonance condition maximizing the zitterbewegung.
摘要
我们研究了由于自旋轨道耦合，Ⅲ-Ⅴ族闪锌矿半导体量子阱中电子波包的颤动。我们的结果表明了这一基本效应的直接实验证据，证实了一个长期存在的理论预测。对于在谐波量子线中的电子运动，我们通过数值和解析方法找到了使颤动最大化的共振条件。
