Charge Transfer Excitations in Insulating Copper Oxides
A. S. Moskvin, S. -L. Drechsler, R. Hayn +1
A semi-quantitative cluster approach is developed to describe the charge transfer (CT) electron-hole excitations in insulating cuprates in a rather wide energy range up to 10- 15 e…

Charge states of strongly correlated 3d oxides: from typical insulator to unconventional electron-hole Bose liquid
A. S. Moskvin
We develop a model approach to describe charge fluctuations and different charge phases in strongly correlated 3d oxides. As a generic model system one considers that of centers ea…
