摘要

具有自旋的量子粒子的维格纳旋转是狭义相对论和量子力学相互作用的迷人结果之一。在本文中，我们证明了在非相对论速度为~ 103 ms−1的大质量自旋为1/2的粒子中，原则上可以直接实验验证Wigner旋转。我们讨论了如何在实验室中使用冷中子进行实验。通过让中子传播足够长的时间，以非相对论速度进行测量成为可能，因为维格纳旋转是一种累积效应。

Proposal for an experiment to verify Wigner's rotation at non-relativistic speeds with massive spin-1/2 particles

The Wigner rotation of quantum particles with spin is one of the fascinating consequences of interplay between special relativity and quantum mechanics. In this paper we show that a direct experimental verification of Wigner's rotation is in principle accessible in the regime of non-relativistic velocities at

\sim 10^{3}

m s^{- 1}

for massive spin-1/2 particles. We discuss how the experiment could be carried out in a laboratory using cold neutrons. The measurement at non-relativistic velocities becomes possible through letting neutrons propagate for a sufficiently long time because Wigner rotation is a cumulative effect.
