Optical Conductivity and Resistivity of a Hole Doped Spin-Fermion Model for Cuprates
M. Morgaghebi, S. Yunoki, A. Moreo
The optical conductivity and Drude weight of a Spin-Fermion model for cuprates are studied as a function of electronic density and temperature. This model develops stripes and robu…
Absence of magic fillings of carrier-doped C in a field-effect transistor
Seiji Yunoki, George A. Sawatzky
Motivated by recent experiments of carrier-doped C in a field-effect transistor (FET), effects of spatial single particle potential variations on Mott-Hubbard (MH) insulator…
Cooperative Jahn-Teller Effect on the Magnetic Structure of Manganese Oxides
Takashi Hotta, Seiji Yunoki, Elbio Dagotto
The magnetic structure of LaMnO is investigated on three-dimensional clusters of MnO octahedra by using a combination of relaxation and Monte Carlo techniques. It is found…
The Phase Separation Scenario for Manganese Oxides
Adriana Moreo, Seiji Yunoki, Elbio Dagotto
Recent computational studies of models for manganese oxides have revealed a rich phase diagram, not anticipated in early calculations in this context performed in the 1950's and 60…
Phase Separation in Models for Manganites: Theoretical Aspects and Comparison with Experiments
E. Dagotto, S. Yunoki, A. Moreo
This paper is an informal review of the present status of the computational studies of models for manganites that recently reported the existence of phase separation at low tempera…
