SCHRÖDINGER INVARIANCE IN DISCRETE STOCHASTIC SYSTEMS
Malte Henkel, Gunter Schütz
Abstract
Local scale invariance for lattice models is studied using new realizations of the Schrödinger algebra. The two-point function is calculated and it turns out that the result can be reproduced from exact two-point correlation functions evaluated in the stationary state of several simple stochastic models.
