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…
