Spin-orbit coupling, strong correlation, and insulator-metal transitions: the J =3\2 ferromagnetic Mott insulator BaNaOsO
Shruba Gangopadhyay, Warren E. Pickett
The double perovskite BaNaOsO (BNOO), an exotic example of a very high oxidation state (heptavalent) osmium compound and also uncommon by being a ferromagnetic Mo…
Analysis of charge states in the mixed valent ionic insulator AgO
Yundi Quan, Warren E. Pickett
The doubly ionized copper ion provides, originally in LaCuO and later in many more compounds, the platform for high temperature superconductivity when it is forced to…
Dielectric Response of Electron-doped Ionic Superconductor LiZrNCl
Antia S. Botana, Warren E. Pickett
When electron doped, the layered transition metal nitrides NCl ( = group IVB transition metal ion) become impressive superconductors with critical temperature T…
Strong interactions, narrow bands, and dominant spin-orbit coupling in Mott insulating quadruple perovskite CaCo3V4O12
H. B. Rhee, W. E. Pickett
We investigate the electronic and magnetic structures and the character and direction of spin and orbital moments of the recently synthesized quadruple perovskite cobaltovanadate C…
Unquenched orbital moment in the Mott insulating antiferromagnet KOsO4
Young-Joon Song, Kyo-Hoon Ahn, K. -W. Lee +1
Applying the correlated electronic structure method based on density functional theory plus the Hubbard interaction, we have investigated the tetragonal scheelite structure Mot…
Magnetic correlations and pairing in the 1/5-depleted square lattice Hubbard model
Ehsan Khatami, Rajiv R. P. Singh, Warren E. Pickett +1
We study the single-orbital Hubbard model on the 1/5-depleted square lattice geometry, which arises in such diverse systems as the spin-gap magnetic insulator CaV4O9 and ordered-va…
