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…
C-axis Response of a High-T_{c} Superconductor with D-Density Wave Order
Wonkee Kim, Jian-Xin Zhu, J. P. Carbotte +1
The microscopic origin of the pseudogap state which exists in the underdoped cuprates remains unknown. The -axis properties in the pseudogap regime are particularly anomalous. W…
Quasiparticle States around a Nonmagnetic Impurity in D-Density-Wave State of High- Cuprates
Jian-Xin Zhu, Wonkee Kim, C. S. Ting +1
Recently Chakravarty {\em et al.} proposed an ordered -density wave (DDW) state as an explanation of the pseudogap phase in underdoped high-temperature cuprates. We study the co…
Quasiparticle States at a d-Wave Vortex Core in High-Tc Superconductors: Induction of Local Spin Density Wave Order
Jian-Xin Zhu, C. S. Ting
The local density of states (LDOS) at one of the vortex lattice cores in a high Tc superconductor is studied by using a self-consistent mean field theory including interactions for…
Quasiparticle Localization in Disordered d-Wave Superconductors
Jian-Xin Zhu, D. N. Sheng, C. S. Ting
An extensive numerical study is reported on disorder effect in two-dimensional d-wave superconductors with random impurities in the unitary limit. It is found that a sharp resonant…
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…
Spontaneous flux in a d-wave superconductor with time-reversal-symmetry-broken pairing state at {110} boundaries
Jian-Xin Zhu, C. S. Ting
The induction of an s-wave component in a d-wave superconductor is considered. Near the {110}-oriented edges of such a sample, the induced s-wave order parameter together with d-wa…
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…
Spin-Charge Separation in the Model: Magnetic and Transport Anomalies
Z. Y. Weng, D. N. Sheng, C. S. Ting
A real spin-charge separation scheme is found based on a saddle-point state of the model. In the one-dimensional (1D) case, such a saddle-point reproduces the correct asympto…
