Zooming-in on the charge ordering in YBa2Cu3O6.5
D. L. Feng, A. Rusydi, P. Abbamonte +9
We report direct evidence of charge/orbital ordering of low energy electronic states of in YBaCuO ortho-II phase in both the chain and the CuO plan…
Two-dimensional Hubbard-Holstein bipolaron
Alexandru Macridin, George. A. Sawatzky, Mark Jarrell
We present a diagrammatic Monte Carlo study of the properties of the Hubbard-Holstein bipolaron on a two-dimensional square lattice. With a small Coulomb repulsion, U, and with inc…
Structural, electronic, and magneto-optical properties of YVO
A. A. Tsvetkov, F. P. Mena, P. H. M. van Loosdrecht +6
Optical and magneto-optical properties of YVO single crystal were studied in FIR, visible, and UV regions. Two structural phase transitions at 75 K and 200 K were observed and…
Absence of magic fillings of carrier-doped C in a field-effect transistor
Seiji Yunoki, George A. Sawatzky
Motivated by recent experiments of carrier-doped C in a field-effect transistor (FET), effects of spatial single particle potential variations on Mott-Hubbard (MH) insulator…
Does EELS haunt your photoemission measurements?
K. Schulte, M. A. James, P. G. Steeneken +4
It has been argued in a recent paper by R. Joynt (R. Joynt, Science 284, p 777 (1999)) that in the case of poorly conducting solids the photoemission spectrum close to the Fermi En…
Spin and orbital excitations in magnetic insulators with Jahn-Teller ions
J. van den Brink, W. Stekelenburg, D. I. Khomskii +2
The elementary excitations of a model Hamiltonian that captures the low energy behavior of a simple two-fold degenerate Hubbard Hamiltonian with Hund's rule coupling, is studied. T…
