Order N Monte Carlo Algorithm for Fermion Systems Coupled with Fluctuating Adiabatical Fields
Nobuo Furukawa, Yukitoshi Motome
An improved algorithm is proposed for Monte Carlo methods to study fermion systems interacting with adiabatical fields. To obtain a weight for each Monte Carlo sample with a fixed…
Disorder Effect on Spin Excitation in Double Exchange Systems
Yukitoshi Motome, Nobuo Furukawa
Spin excitation spectrum is studied in the double exchange model in the presence of disorder. Spin wave approximation is applied in the lowest order of 1/S expansion. The disorder…
Monte Carlo Study of Doping Change and Disorder Effect on Double Exchange Ferromagnetism
Yukitoshi Motome, Nobuo Furukawa
Phase diagram and critical properties are studied for three-dimensional double exchange model with and without quenched disorder. Employing the Monte Carlo method and the systemati…
Competing Orders and Disorder-induced Insulator to Metal Transition in Manganites
Yukitoshi Motome, Nobuo Furukawa, Naoto Nagaosa
Effects of disorder on the two competing phases, i.e., the ferromagnetic metal and the commensurate charge/lattice ordered insulator, are studied by Monte Carlo simulation. The dis…
