Striped metal in two-dimensional d–p model

We investigate the dynamical stripe correlation in the two-dimensional d–p model on the basis of the dynamical cluster approximation combined with the unrestricted fluctuation exchange approximation. We obtain the fully self-consistent solutions near 1/8-filling. Our obtained solutions are completel...

Description
Summary:We investigate the dynamical stripe correlation in the two-dimensional d–p model on the basis of the dynamical cluster approximation combined with the unrestricted fluctuation exchange approximation. We obtain the fully self-consistent solutions near 1/8-filling. Our obtained solutions are completely two-dimensional when we see only the static components. However, the charge correlation functions reflect the existence of the quasi-one-dimensional fluctuation for higher energies. This fluctuation tends to form the vertical stripe state.
