The Ferromagnetic Kondo Model for Manganites: Phase Diagram and Charge Segregation Effects
E. Dagotto, S. Yunoki, A. L. Malvezzi +5
The phase diagram of the ferromagnetic Kondo model for manganites is investigated using computational techniques. In clusters of dimensions 1 and 2, Monte Carlo simulations in the…
Enhancement of Antiferromagnetic Correlations Induced by Nonmagnetic Impurities: Origin and Predictions for NMR Experiments
Markus Laukamp, George Balster Martins, Claudio J. Gazza +5
Spin models that have been proposed to describe dimerized chains, ladders, two dimensional antiferromagnets, and other compounds are here studied when some spins are replaced by sp…
Diagonalization in Reduced Hilbert Spaces using a Systematically Improved Basis: Application to Spin Dynamics in Lightly Doped Ladders
E. Dagotto, G. B. Martins, J. Riera +2
A method is proposed to improve the accuracy of approximate techniques for strongly correlated electrons that use reduced Hilbert spaces. As a first step, the method involves a cha…
Phase Separation in Electronic Models for Manganites
S. Yunoki, J. Hu, A. L. Malvezzi +3
The Kondo lattice Hamiltonian with ferromagnetic Hund's coupling as a model for manganites is investigated. The classical limit for the spin of the (localized) electrons i…
