Quantum Melting of Charge Order due to Frustration in Two-Dimensional Quarter-Filled Systems
Jaime Merino, Hitoshi Seo, Masao Ogata
The effect of geometrical frustration in a two-dimensional 1/4-filled strongly correlated electron system is studied theoretically, motivated by layered organic molecular crystals.…
Re-entrant Behavior and Gigantic Response in Disordered Spin-Peierls System
Hitoshi Seo, Yukitoshi Motome, Naoto Nagaosa
Effects of disorder and external field on the competing spin-Peierls and antiferromagnetic states are studied theoretically in terms of the numerical transfer matrix method applied…
Coexistence of Charge Order and Spin-Peierls Lattice Distortion in One-Dimensional Organic Conductors
Makoto Kuwabara, Hitoshi Seo, Masao Ogata
The electronic properties of quarter-filled organic materials showing spin-Peierls transition are investigated theoretically. By studying the one-dimensional extended Peierls-Hubba…
One-Dimensional Confinement and Enhanced Jahn-Teller Instability in LaVO
Yukitoshi Motome, Hitoshi Seo, Zhong Fang +1
Ordering and quantum fluctuations of orbital degrees of freedom are studied theoretically for LaVO in spin-C-type antiferromagnetic state. The effective Hamiltonian for the orb…
New aspects of Verway transition in magnetite
Hitoshi Seo, Masao Ogata, Hidetoshi Fukuyama
A new mechanism of the Verway transition in magnetite (Fe3O4), which has been argued to be a charge ordering transition so far, is proposed. Based on the mean field calculations fo…
