Explanation of Giant Cluster Coexistence in Doped Manganites and Other Compounds
Adriana Moreo, Matthias Mayr, Adrian Feiguin +2
Computational studies show the generation of large coexisting metallic and insulating clusters with equal electronic density in models for manganites. The clusters are induced by d…
Magnetic Domains and Stripes in the Spin-Fermion Model for Cuprates
Charles Buhler, Seiji Yunoki, Adriana Moreo
Monte Carlo simulations applied to the Spin-Fermion model for cuprates show the existence of antiferromagnetic spin domains and charge stripes upon doping. The stripes are partiall…
Pseudogap Formation in Models for Manganites
Adriana Moreo, Seiji Yunoki, Elbio Dagotto
The density-of-states (DOS) and one-particle spectral function of the one- and two-orbital models for manganites, the latter with Jahn-Teller phonons, are evalu…
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…
