Spin-1 nonlocal force structures:As simple as I can describe it.

  1. Jun 15, 2004 #1
    The simplest state transition experiment for a spin-1 particle is, S -> T -> S. This expression describes two events, 1) polarization, S -> T, upon entry into a magnetic field volume of a Stern-Gerlach T Segment, and 2) the depolarization, T - > S, when exiting the SG segment into a field free region.

    The generalized S state (either +S, +-S or -S) reflect the orientation of the particle spin vector parallel to the magnetic field/gradient of the S segment. + indicates 'up' motion along the S line (or z-axis). The polarization event, S -> T orients S to some T state orientation (either +T, +-T or -T). We do no harm by defining the states as magnetic monople spin vectors.

    The T -> S reformation always occurs in a field free region immediately outside the T segment.This reformed spin state is characteristic of spin-1 particles manifest as inertial platforms.

    Compass needles find north by force the the earth's magnetic field. The T -> S reformation is guaranteed by unobserved, or nonlocal elements of S defined as 00. We include nonlocal elements, without any physical assumption attached, in S as S = S(1 00 ). The '1' inserted for instructional purposes is understood as equivalent to '+'.

    The transition expression now is:

    S = S(1 00) -> T (1 00) -> (_ 00) -> S(1 00) = S.

    The fourth term (_ 00) emphacises the unperturbed nature of the nonlocal elements guaranteeing the reformation of the +S state in the field free region.

    The forces guaranteeing the reformation of the +S state, the 00, are unobserved, or nonlocal and not X,Y components of the +S state.
