Phase competitions and coexistences in quasi-one-dimensional molecular conductors: exact diagonalization study
Yuichi Otsuka, Hitoshi Seo, Yukitoshi Motome +1
We investigate ground state properties of a quasi-one-dimensional electron-lattice coupled model for quarter-filled molecular conductors. The effective one-dimensional extended Hub…
Finite-Temperature Phase Diagram of Quasi-One-Dimensional Molecular Conductors: Quantum Monte Carlo Study
Yuichi Otsuka, Hitoshi Seo, Yukitoshi Motome +1
Finite-temperature phase transitions in quasi-one-dimensional quarter-filled systems are investigated by the extended Hubbard model with electron-lattice coupling. Using a quantum…
First-Principles Computation of YVO3; Combining Path-Integral Renormalization Group with Density-Functional Approach
Yuichi Otsuka, Masatoshi Imada
We investigate the electronic structure of the transition-metal oxide YVO3 by a hybrid first-principles scheme. The density-functional theory with the local-density-approximation b…
