The spin-1/2 transverse XX chain with regularly alternating bonds and fields

Condensed Matter 2009-10-31 v1

Abstract

We use continued fractions for a study of the thermodynamic properties of the periodic nonuniform spin-1/2 isotropic XY chain in a non-random/random (Lorentzian) transverse field. The obtained results permit to examine the influence of a magnetic field and randomness on the spin-Peierls dimerization.
