CLASSICAL SPIN IN A POTENTIAL-FIELD

We consider an ensemble of restricted discrete random walks in 2 + 1 d imensions. The restriction on the walks is such as to give particles a n intrinsic angular momentum. The walks are embedded in a field which affects the mean free path of the walks. We show that the dynamics of the walks is such that second-order effects are described by a discret e form of Schrodinger's equation for particles in a potential field. T his provides a classical context of the equation which is independent of its quantum context.
