Stochastic Reduction in Nonlinear Quantum Mechanics
D. C. Brody, L. P. Hughston
abstract: Stochastic extensions of the Schrodinger equation have attracted attention
recently as plausible models for state reduction in quantum mechanics. Here we
formulate a general approach to stochastic Schrodinger dynamics in the case of
a nonlinear state space of the type proposed by Kibble. We derive a number of
new identities for observables in the nonlinear theory, and establish general
criteria on the curvature of the state space sufficient to ensure collapse of
the wave function.
