Orbital correlations in ultrathin films of late transition metals
Sergei Ivanov, Joshua Peacock, Sergei Urazhdin
We develop a two-orbital Hubbard model of electron correlations in ultrathin (111)-oriented fcc films of late transition metals such as Co and Ni. Our model indicates that the Mott…

Electronic properties of the mean-field resonating valence bond model of cuprates
Sergei Urazhdin, Sergei Ivanov
We show that the mean-field resonating valence bond approximation proposed in 1987 by Baskaran, Zou, and Anderson describes gapless charge pair excitations confined to the boundari…
