Quantized lattice dynamic effects on the spin-Peierls transition

Quantized lattice dynamic effects on the spin-Peierls transition

The density-matrix renormalization-group method is used to investigate the spin-Peierls transition for Heisenberg spins coupled to quantized phonons. We use a phonon spectrum that interpolates between a gapped, dispersionless (Einstein) limit to a gapless, dispersive (Debye) limit. A variety of theo...
