Stern gerlach question

  1. Nov 15, 2012 #1
    Can I get a spin 1/2 particle to deflect with the aharonov bohm effect.
    Where the B field is zero but A is not? Or will it just change the phase in the state-vector?
    can I get the spin up particles to go one way and the spin down particles to go another way.

    The AB effect acts on charged particles but is independent of spin.
    For particles with spin there is an analogous deflection in electric fields, the Aharonov-Casher effect.

    it seems that if it affects charged particles that it would also affect spin, because spin is affected by a B field.
    thanks for your post

    But not all particles having spin are charged. Stern and Gerlach were using neutral silver atoms in their experiment.

    ok I see your point.
    Thats interesting that it only acts on charged particles.
    So if I shot silver atoms by a solenoid I would not observe the AB-effect.
