Electronic structure and nontrivial topological surface states in ZrRuP and ScPd compounds
Armindo S. Cuamba, Hong-Yan Lu, Lei Hao +1
In this paper, we investigate the topological properties of ZrRuP and ScPd using the first-principles calculations. We calculate the electronic structure, surface states, and…
Type-II Dirac cone and Dirac cone protected by nonsymmorphic symmetry in carbon-lithium compound (C4Li)
Armindo S. Cuamba, Pavan Hosur, Hong-Yan Lu +2
In this work, we predict a novel band structure for Carbon-Lithium(C4Li) compound using the first-principles method. We show that it exhibits two Dirac points near the Fermi level;…
Topological insulator ribbon: Surface states and dynamical response
Lei Hao, Peter Thalmeier, T. K. Lee
We study theoretically the distributions of charge and spin polarization of a topological insulator ribbon, with a realistic rectangular cross section. Due to constriction in two l…
Impairment of double exchange mechanism in electron transport of iron pnictides
Lei Hao, Chi-Cheng Lee, T. K. Lee
Double exchange mechanism is believed to favor transport along ferromagnetic directions, the failure of which in explaining the unusual resistivity anisotropy in iron pnictides is…
Surface spectral function in the superconducting state of a topological insulator
Lei Hao, T. K. Lee
We discuss the surface spectral function of superconductors realized from a topological insulator, such as the copper-intercalated BiSe. These functions are calculated…
Thermopower of multilayer graphene
Lei Hao, T. K. Lee
We systematically calculate thermopower of biased and unbiased multilayer grphene systems. The effect of screening to a bias field perpendicular to the graphene planes is taken int…
