Shot noise in a metal close to Mott transition
Yiou Zhang, Shashi Pandey, Sergei Ivanov +2
SrIrO is a metallic complex oxide with unusual electronic and magnetic properties believed to originate from electron correlations due to its proximity to Mott metal-insulator…
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…
Orbital entanglement mechanism of superconductivity in cuprates
Alexander Mitrofanov, Sergei Urazhdin
We utilize a 1d Hubbard model to show that the superconductivity in cuprate superconductors likely arises due to the orbital entanglement between holes in the copper oxide plane me…
