Quantum phase transition in the one-dimensional extended Peierls-Hubbard model

Abstract:
We consider the one-dimensional extended Hubbard model in the presence of an explicit dimerization δ. For a sufficiently strong nearest neighbor repulsion we establish the existence of a quantum phase transition between a mixed bond-order wave and charge-density wave phase from a pure bond-order wave phase. This phase transition is in the universality class of the two-dimensional Ising model. © 2006 The American Physical Society.
