Surface states of gapped electron systems and semi-metals
Xin-Zhong Yan, C. S. Ting
With a generic lattice model for electrons occupying a semi-infinite crystal with a hard surface, we study the eigenstates of the system with a bulk band gap (or the gap with nodal…
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…
Phase boundary of spin-polarized-current state of electrons in bilayer graphene
Xin-Zhong Yan, Yinfeng Ma, C. S. Ting
Using a four-band Hamiltonian, we study the phase boundary of spin-polarized-current state (SPCS) of interacting electrons in bilayer graphene. The model of spin-polarized-current…
Current orderings of interacting electrons in bilayer graphene
Xin-Zhong Yan, C. S. Ting
By taking into account the possibility of all the intralayer as well as the interlayer current orderings, we derive an eight-band model for interacting electrons in bilayer graphen…
Spin-Polarized-Current State of Electrons in Bilayer Graphene
Xin-Zhong Yan, C. S. Ting
We propose a model of spin-polarized-current state for electrons in bilayer graphene. The model resolves the puzzles as revealed by experiments that (a) the energy gap $E_{\rm gap}…
