Directional dependence of spin currents induced by Aharonov-Casher phase
We have calculated the persistent spin current of an open ring induced by the Aharonov-Casher phase. For unpolarized electrons there exist no persistent charge currents, but persistent spin currents. We show that, in general, the magnitude of the persistent spin current in a ring depends on the direction of the direct current flow from one reservoir to another. The persistent spin current is mo...
متن کاملTesting Bell’s inequality using Aharonov-Casher effect
We propose the Aharonov-Casher (AC) effect for four entangled spin-half particles carrying magnetic moments in the presence of impenetrable line charge. The four particle state undergoes AC phase shift in two causually disconnected region which can show up in the correlations between different spin states of distant particles. This correlation can violate Bell’s inequality, thus displaying the ...
متن کاملTesting Leggett's Inequality Using Aharonov-Casher Effect
Bell's inequality is established based on local realism. The violation of Bell's inequality by quantum mechanics implies either locality or realism or both are untenable. Leggett's inequality is derived based on nonlocal realism. The violation of Leggett's inequality implies that quantum mechanics is neither local realistic nor nonlocal realistic. The incompatibility of nonlocal realism and qua...
متن کاملComments on the Aharonov-Casher effect
We study the basic requirements for neutron confinement in the framework of some 3-D Aharonov-Casher configurations PACS number(s): 03.65Ge, 03.65.Bz, 12.60.J, 11.30.P. Aharonov and Casher (AC) pointed out the existence of a quantum mechanical process [1–3] wherein the behavior of an uncharged dipole is affected by the presence of an electric field. Let us imagine an electrically charged object...
متن کاملComment on "Aharonov-Casher and scalar Aharonov-Bohm topological effects".
We reexamine the topological and nonlocal natures of the Aharonov-Casher and scalar Aharonov-Bohm phase effects. The underlying U(1) gauge structure is exhibited explicitly. And the conditions for developing topological Aharonov-Casher and scalar Aharonov-Bohm phases are clarified. We analyze the arguments of M. Peshkin and H. J. Lipkin [Phys. Rev. Lett. 74, 2847 (1995)] in detail and show that...
