Unconventional proximity effect and inverse spin-switch behavior in a model manganite-cuprate-manganite trilayer system

Juan Salafranca, Satoshi Okamoto

The proximity effect in a model manganite-cuprate system is investigated theoretically. We consider a situation in which spin-polarized electrons in manganite layers antiferromagne…

Nonlinear transport through two-terminal strongly-correlated heterostructures: A dynamical-mean-field approach

Satoshi Okamoto

The dynamical-mean-field method is applied to investigate the transport properties of heterostructures consisting of a strongly-correlated electron system connected to metallic lea…

Enhanced Superconductivity in Superlattices of High- Cuprates

Satoshi Okamoto, Thomas A. Maier

The electronic properties of multilayers of strongly correlated models for cuprate superconductors are investigated using cluster dynamical mean-field techniques. We focus on combi…

NaV2O4: a Quasi-1D Metallic Antiferromagnet with Half-Metallic Chains

K. Yamaura, M. Arai, A. Sato +6

NaV2O4 crystals were grown under high pressure using a NaCl flux, and the crystals were characterized with X-ray diffraction, electrical resistivity, heat capacity, and magnetizati…

Nonequilibrium transport and optical properties of model metal--Mott-insulator--metal heterostructures

Satoshi Okamoto

Electronic properties of heterostructures in which a finite number of Mott-insulator layers are sandwiched by semi-infinite metallic leads are investigated by using the dynamical-m…

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…
