Dynamically generated dimension reduction and crossover in a spin orbital model

Strongly Correlated Electrons 2007-05-23 v1

Abstract

We study a spin orbital model in which the spin-spin interaction couples linearly to the orbital isospin. Fluctuations drive the transition from paramagnetic state to C type ordered state into a strongly first order one, as observed in V2O3V_2O_3. At T=0, there is a FOCS to FOGS transition. Close to the transition point, the system shows dynamically generated dimension reduction and crossover, resulting in one or more spin reentrant transitions.
