Topological effects at short antiferromagnetic Heisenberg chains
Jizhong Lou, Shaojin Qin, Tai-Kai Ng +1
The manifestations of topological effects in finite antiferromagnetic Heisenberg chains is examined by density matrix renormalization group technique in this paper. We find that di…

Transition from band insulator to Mott insulator in one dimension: Critical behavior and phase diagram
Jizhong Lou, Shaojin Qin, Tao Xiang +3
We report a systematic study of the transition from a band insulator (BI) to a Mott insulator (MI) in a one-dimensional Hubbard model at half-filling with an on-site Coulomb intera…

Thermodynamics of the bilinear-biquadratic spin one Heisenberg chain
Jizhong Lou, Tao Xiang, Zhaobin Su
The magnetic susceptibility and specific heat of the one-dimensional S=1 bilinear-biquadratic Heisenberg model are calculated using the transfer matrix renormalization group. By co…
