Spin-Peierls vs. Peierls distortions in a family of conjugated Polymers
arXiv:cond-mat/9705121 · doi:10.1103/PhysRevB.56.1751
Abstract
Distortions in a family of conjugated polymers are studied within two complementary approaches, i.e. within a many-body Valence Bond (VB) approach using a transfer matrix technique to treat the Heisenberg model of the systems, and also in terms of the tight-binding band-theoretic model with interactions limited to nearest neighbors. The computations indicate that both methods predict the presence or absence of the same distortions in most of the polymers studied.
