Phys. Rev. A 69, 032112 (2004) [7 pages]Berry phase in entangled systems: A proposed experiment with single neutronsReceived 15 September 2003; published 25 March 2004 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. © 2004 The American Physical Society URL:
