Temperature-dependent spectral function of a Kondo impurity in an -wave superconductor
Chenrong Liu, Yixuan Huang, Yan Chen +1
Using the numerical renormalization group method, the effect due to a Kondo impurity in an -wave superconductor is examined at finite temperature (). The -behaviors of the…
Orbital magnetization of interacting Dirac fermions in graphene
Xin-Zhong Yan, C. S. Ting
We present a formalism to calculate the orbital magnetization of interacting Dirac fermions under a magnetic field. In this approach, the divergence difficulty is overcome with a s…
Integer Quantum Hall Effect of Interacting Electrons in Graphene
Xin-Zhong Yan, C. S. Ting
By taking into account the charge and spin orderings and the exchange interactions between all the Landau levels, we investigate the integer quantum Hall effect of electrons in gra…
Interaction driven quantum phase transition in fractional quantum spin Hall effects
Wei Li, D. N. Sheng, C. S. Ting +1
By means of finite size exact diagonalization we theoretically study the electronic many-body effects on the nearly flat-band structure with time-reversal symmetry in a checkerboar…
Ordered-Current State of Electrons in Bilayer Graphene
Xin-Zhong Yan, C. S. Ting
Based on the four-band continuum model, we study the ordered-current state (OCS) for electrons in bilayer graphene at the charge neutrality point. The present work resolves the puz…
Compressibility of Interacting Electrons in Bilayer Graphene
Xin-Zhong Yan, C. S. Ting
Using the renormalized-ring-diagram approximation, we study the compressibility of the interacting electrons in bilayer graphene. The compressibility is equivalent to the spin susc…
Study of two-dimensional electron systems in the renormalized-ring-diagram approximation
Xin-Zhong Yan, C. S. Ting
With a super-high-efficient numerical algorithm, we are able to self-consistently calculate the Green's function in the renormalized-ring-diagram approximation for a two-dimensiona…
Theory of Ferromagnetic Metal to Paramagnetic Insulator Transition i in R_{1-x}A_{x}MnO_{3}
L. Sheng, D. N. Sheng, C. S. Ting
The double-exchange model for the Mn oxides with orbital degeneracy is studied with including on-site Coulomb repulsion, Jahn-Teller (J-T) coupling and doping-induced disorder. In…
