论文摘要
在安德森本地化系统中，平均而言，具有非零初始速度的量子粒子返回其起源。最近发现的行为称为量子回旋镖效应。最初认为时间逆转不变性是这种现象存在的必要条件。我们从理论上使用具有自旋轨道耦合的一维系统分析了对称性破坏对现象的影响，并表明时间逆转不变性对于Boomerang效应并不是必需的。
In an Anderson localized system, a quantum particle with a nonzero initial velocity returns, on average, to its origin. This recently discovered behavior is known as the quantum boomerang effect. Time reversal invariance was initially thought to be a necessary condition for the existence of this phenomenon. We theoretically analyze the impact of the symmetry breaking on the phenomenon using a one-dimensional system with a spin-orbit coupling and show that the time reversal invariance is not necessary for the boomerang effect to occur.
