Possible Metastable State Triggered by Competition of Peierls State and Charge Ordered State
Y. Omori, M. Tsuchiizu, Y. Suzumura
We examine a Peierls ground state and its competing metastable state in the one-dimensional quarter-filled Peierls-Hubbard model with the nearest-neighbor repulsive interaction V a…
Peierls ground state and excitations in the electron-lattice correlated system (EDO-TTF)_{2}X
M. Tsuchiizu, Y. Suzumura
We investigate the exotic Peierls state in the one-dimensional organic compound (EDO-TTF)_{2}X, wherein the Peierls transition is accompanied by the bending of molecules and also b…
Charge-Ordered State versus Dimer-Mott Insulator at Finite Temperatures
Hideo Yoshioka, Masahisa Tsuchiizu, Hitoshi Seo
We theoretically investigate the competition between charge-ordered state and Mott insulating state at finite temperatures in quarter-filled quasi-one-dimensional electron systems,…
Magnetic response and quantum critical behavior in the doped two-leg extended Hubbard ladder
M. Tsuchiizu, Y. Suzumura
We have investigated quantum critical behavior in the doped two-leg extended Hubbard ladder, by using a weak-coupling bosonization method. In the ground state, the dominant fluctua…
Charge-Density-Wave Formation in the Doped Two-Leg Extended Hubbard Ladder
M. Tsuchiizu, Y. Suzumura
We investigate electronic properties of the doped two-leg Hubbard ladder with both the onsite and the nearest-neighbor Coulomb repulsions, by using the the weak-coupling renormaliz…
Ground-state phase diagram of the one-dimensional half-filled extended Hubbard model
M. Tsuchiizu, A. Furusaki
We revisit the ground-state phase diagram of the one-dimensional half-filled extended Hubbard model with on-site (U) and nearest-neighbor (V) repulsive interactions. In the first h…
