Chiral Spin Liquid in Correlated Topological Insulator
Jing He, Su-Peng Kou, Ying Liang +1
In this paper, we investigate the topological Hubbard model - the spinful Haldane model with on-site interaction on honeycomb lattice with spin rotation symmetry by using slave-rot…
Collective spin mode in a multi-component system of coupled itinerant and localized electrons
Fan Yang, Su-Peng Kou, Zheng-Yu Weng
We study collective spin excitations of a magnetically ordered state in a multi-component system composed of both itinerant electrons and local moments. Here the induced spin-densi…
Reduced fidelity in Kitaev honeycomb model
Zhi Wang, Tianxing Ma, Shi-Jian Gu +1
We study the reduced fidelity and reduced fidelity susceptibility in the Kitaev honeycomb model. It is shown that the reduced fidelity susceptibility of two nearest site manifest i…
Effects of edge disorder in nano-scale antiferromagnetic clusters
Wanzhou Zhang, Wenan Guo, Kaj H Hoglund +2
We study the distribution of local magnetic susceptibilities in the two-dimensional antiferromagnetic S=1/2 Heisenberg model on various random clusters, in order to determine wheth…
Hardcore bosons on the dual of the bowtie lattice
Wanzhou Zhang, Laixi Li, Wenan Guo
We study the zero temperature phase diagram of hardcore bosons on the dual of the bowtie lattice. Two types of striped diagonal long-range order (striped order I and striped order…
