Metal-insulator transition in superlattices
Shuai Dong, Rong Yu, Seiji Yunoki +3
The modulation of charge density and spin order in (LaMnO)/(SrMnO) (=1-4) superlattices is studied via Monte Carlo simulations of the double-exchange model. G…
Fermi Arcs in the Superconducting Clustered State for Underdoped Cuprates
G. Alvarez, E. Dagotto
The one-particle spectral function of a state formed by superconducting (SC) clusters is studied via Monte Carlo techniques. The clusters have similar SC amplitudes but randomly di…
Study of Short-distance Spin and Charge Correlations and Local Density-of-States in the CMR regime of the One-Orbital Model for Manganites
Rong Yu, Shuai Dong, Cengiz Sen +2
The metal-insulator transition, and the associated magnetic transition, in the colossal magnetoresistance (CMR) regime of the one-orbital model for manganites is here studied using…
Competing Ferromagnetic and Charge-Ordered States in Models for Manganites: the Origin of the CMR Effect
Cengiz Sen, Gonzalo Alvarez, Elbio Dagotto
The one-orbital model for manganites with cooperative phonons and superexchange coupling has been investigated via large-scale Monte Carlo (MC) simulations. Results fo…
Large-Scale Monte Carlo Study of a Realistic Lattice Model for Ga_(1-x)Mn_xAs
Yucel Yildirim, Gonzalo Alvarez, Adriana Moreo +1
The properties of Mn-doped GaAs are studied at several doping levels and hole compensations, using a real-space Hamiltonian on an fcc lattice that reproduces the valence bands of u…
Calculation of Dynamical and Many-Body Observables with the Polynomial Expansion Method for Spin-Fermion Models
G. Alvarez, T. C. Schulthess
The calculation of two- and four-particle observables is addressed within the framework of the truncated polynomial expansion method (TPEM). The TPEM replaces the exact diagonaliza…
