Charge ordering in the spinels AlVO and LiVO
Y. Z. Zhang, P. Fulde, P. Thalmeier +1
We develop a microscopic theory for the charge ordering (CO) transitions in the spinels AlVO and LiVO (under pressure). The high degeneracy of CO states is lifted b…

Metal-insulator transition in the quarter- filled frustrated checkerboard lattice
Y. Z. Zhang, Tran Minh-Tien, V. Yushankhai +1
We study the electronic structure and correlations in the geometrically frustrated two dimensional checkerboard lattice. In the large U limit considered here we start from an exten…

Study of the ionic Peierls-Hubbard model using density matrix renormalization group methods
Y. Z. Zhang, C. Q. Wu, H. Q. Lin
Density matrix renormalization group methods are used to investigate the quantum phase diagram of a one-dimensional half-filled ionic Hubbard model with bond-charge attraction, whi…
