Topological BF field theory description of topological insulators
Topological BF field theory description topological insulators
2010/12/27
Topological phases of matter are described universally by topological field theories in the same way that symmetry-breaking phases of matter are described by Landau-Ginzburg field theories. We propos...
Electrically Controllable Surface Magnetism on the Surface of Topological Insulators
Electrically Controllable Surface Magnetism Surface of Topological Insulators
2014/5/28
We study theoretically the RKKY interaction between magnetic impurities on the surface of threedimensional topological insulators, mediated by the helical Dirac electrons. Exact analytical expression ...
Track Electrostatic Model for Describing Secondary Ion Emission of Insulators
Track Electrostatic Model Secondary Ion Emission Insulators
2010/10/15
A model based on the nuclear track potential is described and used to predict trajectories and the energy distribution of secondary ions emitted by insulating targets. In this model, the electric fiel...
