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…

Quantum phase transitions of the asymmetric three-leg spin tube
Tôru Sakai, Masahiro Sato, Kouichi Okunishi +3
We investigate quantum phase transitions of the S=1/2 three-leg antiferromagnetic spin tube with asymmetric inter-chain (rung) exchange interactions. On the basis of the electron t…
