Symmetry breaking in topological insulators and high temperature superconductors

ORAL

Abstract

We study symmetry breaking in three dimensional topological insulators due to various magnetic and nonmagnetic 3d transition metal dopants such as Cr and V. In addition, variational cluster approximation based Hubbard-Rashba systems are studied in order to identify effects of correlations on various geometries. Spin-Hall effect in small clusters, such as ladders with various boundary conditions, is also addressed.
