Energy Centroids in the presence of random interactions
Y. M. Zhao, A. Arima, N. Yoshida +3
In this paper we study energy centroids such as those with fixed spin and isospin, those with fixed irreducible representations for bosons, in the presence of random two-body and/o…

Emergence of Long Period Antiferromagnetic Orders from Haldane Phase in S=1 Heisenberg Chains with D-Modulation
Kazuo Hida, Wei Chen
The effect of spatial modulation of the single-site anisotropy D on the ground state of the S=1 Heisenberg chains is investigated. In the case of period 2 modulation, it is found t…

Quantum vs. Classical Magnetization Plateaus of S=1/2 Frustrated Heisenberg Chains
Kazuo Hida, Ian Affleck
The competition between quantum and classical magnetization plateaus of S=1/2 frustrated Heisenberg chains with modified exchange couplings is investigated. The conventional S=1/2…
