Ordering and Fluctuation of Orbital and Lattice Distortion in Perovskite Manganese Oxides
Yukitoshi Motome, Masatoshi Imada
Roles of orbital and lattice degrees of freedom in strongly correlated systems are investigated to understand electronic properties of perovskite Mn oxides such as La_{1-x}Sr_{x}Mn…

Metal-Insulator Transition in Mn Perovskite Compounds
Yukitoshi Motome, Hiroki Nakano, Masatoshi Imada
We discuss Mott insulating and metallic phases of a model with orbital degeneracy to understand physics of Mn perovskite compounds. Quantum Monte Carlo and Lanczos diagonaliz…
