Electron Doping of Cuprates via Interfaces with Manganites
S. Yunoki, A. Moreo, E. Dagotto +3
The electron doping of undoped high- cuprates via the transfer of charge from manganites (or other oxides) using heterostructure geometries is here theoretically discussed. Th…
Band insulator to Mott insulator transition in a bilayer Hubbard model
S. S. Kancharla, S. Okamoto
The ground state phase diagram of the half-filled repulsive Hubbard model in a bilayer is investigated using cluster dynamical mean field theory. For weak to intermediate values of…
Novel Phase Between Band and Mott Insulators in Two Dimensions
S. S. Kancharla, E. Dagotto
We investigate the ground state phase diagram of the half-filled repulsive Hubbard model in two dimensions in the presence of a staggered potential , the so-called ionic Hubbard…
Metallic interface at the boundary between band and Mott insulators
S. S. Kancharla, E. Dagotto
Motivated by experiments on atomically smooth layers of LaTiO, a Mott insulator, sandwiched between layers of SrTiO, a band insulator, a simple model for such heterostructu…
Anomalous superconductivity and its competition with antiferromagnetism in doped Mott insulators
S. S. Kancharla, B. Kyung, D. Senechal +4
Proximity to a Mott insulating phase is likely to be an important physical ingredient of a theory that aims to describe high-temperature superconductivity in the cuprates. Quantum…
Pseudogap induced by short-range spin correlations in a doped Mott insulator
B. Kyung, S. S. Kancharla, D. Sénéchal +3
We study the evolution of a Mott-Hubbard insulator into a correlated metal upon doping in the two-dimensional Hubbard model using the Cellular Dynamical Mean Field Theory. Short-ra…
