Plasmon damping rates in Coulomb-coupled two-dimensional layers in a heterostructure
Dipendra Dahal, Godfrey Gumbs, Andrii Iurov +1
The Coulomb excitations of charge density oscillation are calculated for a double-layer heterostructure. Specifically, we consider two-dimensional (2D) layers of silicene and graph…
Graphane with carbon dimer defects: Robust in-gap states and a scalable two-dimensional platform for quantum computation
Lei Hao, Hong-Yan Lu, C. S. Ting
We study the energy level structures of the defective graphane lattice, where a carbon dimer defect is created by removing the hydrogen atoms on two nearest-neighbor carbon sites.…
Irradiated three-dimensional Luttinger semimetal: A factory for engineering Weyl semimetals
Sayed Ali Akbar Ghorashi, Pavan Hosur, Chin-Sen Ting
We study the interaction between elliptically polarized light and a three-dimensional Luttinger semimetal with quadratic band touching using Floquet theory. In the absence of light…
Emergent topological mirror insulator in t2g-orbital systems
Yuan-Yen Tai, Cheng-Ching Joseph Wang, Matthias J. Graf +2
The electronic band structure of iron pnictides exhibits four Dirac cones, which are due to crystal symmetry and orbital bonding orientation. This hallmark signature presents the p…
Surface states scattering from a step defect in topological insulator Bi_{2}Te_{3}
Jin An, C. S. Ting
We study theoretically by a quantum-mechanical approach the general scattering problem of a straight step defect on the surface of topological insulator $\mathrm{Bi}_{2}\mathrm{Te}…
Resonant Spin Polarization and Hall Effects in a Two-Dimensional Electron Gas
Degang Zhang, Yao-Ming Mu, C. S. Ting
We have studied transport properties in a two-dimensional electron gas with equal Rashba and Dresselhaus spin-orbit interactions under a perpendicular magnetic field. By employing…
