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