纠缠系统中的Berry相:一个提议的单中子实验

Berry phase in entangled systems: a proposed experiment with single neutrons

Reinhold A. Bertlmann, Katharina Durstberger, Yuji Hasegawa, Beatrix C. Hiesmayr

摘要:

研究了几何相位,特别是Berry相位对纠缠自旋为1/2系统的影响.我们详细讨论的情况下,几何相位生成的希尔伯特空间的一部分。我们能够通过使用"自旋回波“方法来消除动力学相位的影响。我们分析了Berry相位对Bell角的影响以及对贝尔不等式的最大破坏。此外,我们建议在中子干涉测量的实验实现我们的设置。

英文摘要:

The influence of the geometric phase, in particular the Berry phase, on an entangled spin-1/2 system is studied. We discuss in detail the case, where the geometric phase is generated only by one part of the Hilbert space. We are able to cancel the effects of the dynamical phase by using the ``spin-echo'' method. We analyze how the Berry phase affects the Bell angles and the maximal violation of a Bell inequality. Furthermore we suggest an experimental realization of our setup within neutron interferometry.
