Phase Diagram of Kane-Mele Hubbard model at small doping
Gaurav Kumar Gupta, D. N. Sheng, C. S. Ting
Recent experiment on MoTe-WTe twisted bi-layer demonstrated physics of Kane-Mele (KM) as well as Haldane models. Although topological properties of KM model has been studie…
Nature of spin-charge separation
Z. Y. Weng, D. N. Sheng, C. S. Ting
Quasiparticle properties are explored in an effective theory of the model which includes two important components: spin-charge separation and unrenormalizable phase shift. We…
Magnetic Incommensurability in Doped Mott Insulator
Z. Y. Weng, D. N. Sheng, C. S. Ting
In this paper we explore the incommensurate spatial modulation of spin-spin correlations as the intrinsic property of the doped Mott insulator, described by the model. We sho…
Mean-Field Description of Phase String Effect in the Model
Z. Y. Weng, D. N. Sheng, C. S. Ting
A mean-field treatment of the phase string effect in the model is presented. Such a theory is able to unite the antiferromagnetic (AF) phase at half-filling and metallic phas…
