Statistics of Spectra for One-dimensional Quasi-Periodic Systems at the Metal-Insulator Transition
Yoshihiro Takada, Kazusumi Ino, Masanori Yamanaka
We study spectral statistics of one-dimensional quasi-periodic systems at the metal-insulator transition. Several types of spectral statistics are observed at the critical points,…
Orbital Liquid in Perovskite Transition-Metal Oxides
Sumio Ishihara, Masanori Yamanaka, Naoto Nagaosa
We study the effects of the degeneracy of the orbitals as well as the double exchange interaction with spins in perovskite transition-metal oxides. In addition to th…
Conductance through a Magnetic Domain Wall in Double Exchange System
Masanori Yamanaka, Naoto Nagaosa
The conductance through a magnetic domain wall is calculated for the double exchange system as a function of energy and the width of the domain wall. It is shown that when the carr…
Hidden Order and Dimerization Transition in Chains
Masanori Yamanaka, Masaki Oshikawa, Seiji Miyashita
We study ground state properties of the quantum antiferromagnetic chain with a bond alternation \[ H = \sum_{j} [ 1 + δ(-1)^j ] \mbox{\boldmath }_{j} \cdot \mbox{\boldmath…
Exact ground-state correlation functions of the one-dimensional strongly correlated electron models with the resonating-valence-bond ground state
Masanori Yamanaka, Shinsuke Honjo, Yasuhiro Hatsugai +1
We investigate the one-dimensional strongly correlated electron models which have the resonating-valence-bond state as the exact ground state. The correlation functions are evaluat…
A novel intermediate phase in S=2 antiferromagnetic chains with uniaxial anisotropy
M. Oshikawa, M. Yamanaka, S. Miyashita
We study ground state properties of the quantum antiferromagnetic chain with a uniaxially anisotropic Hamiltonian: b…
