Direct perturbation theory on the shift of Electron Spin Resonance

arXiv:cond-mat/0312698 · doi:10.1143/JPSJ.74.283

Abstract

We formulate a direct and systematic perturbation theory on the shift of the main paramagnetic peak in Electron Spin Resonance, and derive a general expression up to second order. It is applied to one-dimensional XXZ and transverse Ising models in the high field limit, to obtain explicit results including the polarization dependence for arbitrary temperature.
