Computational Investigations of the Primary Excited States of Poly(para-phenylene vinylene)
Robert J. Bursill, William Barford
The Pariser-Parr-Pople model of pi-conjugated electrons is solved by the density matrix renormalization group method for the light emitting polymer, poly(para-phenylene vinylene).…

Can Quantum Lattice Fluctuations Destroy the Peierls Broken Symmetry Ground State?
William Barford, Robert J Bursill
The study of bond alternation in one-dimensional electronic systems has had a long history. Theoretical work in the 1930s predicted the absence of bond alternation in the limit of…

Peierls transition in the quantum spin-Peierls model
William Barford, Robert J. Bursill
We use the density matrix renormalization group method to investigate the role of longitudinal quantized phonons on the Peierls transition in the spin-Peierls model. For both the X…
