Topological edge states and quantum Hall effect in the Haldane model
Ningning Hao, Ping Zhang, Zhigang Wang +2
We study the topological edge states of the Haldane's graphene model with zigzag/armchair lattice edges. The Harper equation for solving the energies of the edge states is derived.…
Conservation laws of the Haldane-Shastry type spin chains
Junpeng Cao, Peng He, Yuzhu Jiang +1
A systematic method to construct the complete set of conserved quantities of the Haldane-Shastry type spin chains is proposed. The hidden relationship between the Yang-Baxter relat…
Spontaneous trimerization in two-dimensional Antiferromagnets
Zi Cai, Shu Chen, Yupeng Wang
In this paper, we propose a novel quantum paramagnetic state in two-dimensional antiferromagnets: the spontaneously trimer state, which is constructed by the trimers of spins. Each…
Quantum-Fluctuation-Driven Coherent Spin Dynamics in Small Condensates
Xiaoling Cui, Yupeng Wang, Fei Zhou
We have studied quantum spin dynamics of small condensates of cold sodium atoms. For a condensate initially prepared in a mean field ground state, we show that coherent spin dynami…
Exact solution for infinitely strongly interacting Fermi gases in tight waveguides
Liming Guan, Shu Chen, Yupeng Wang +1
We present an exact analytical solution of the fundamental systems of quasi-one-dimensional spin-1/2 fermions with infinite repulsion for arbitrary confining potential. The eigenfu…
Properties of A Class of Topological Phase Transition
Zi Cai, Shu Chen, Supeng Kou +1
The properties of a class of topological quantum phase transition (TQPT) are analyzed based on a model proposed by Haldane. We study the effect of finite temperature on this phase…
