How to compute topological invariants ?
Alexey A. Soluyanov (Institute for Theoretical Physics, ETH Zurich)
par - 14 octobre 2014
In this talk I will present methods to compute topological invariants of band structures. I will discuss Z and Z2 invariants of topological insulators, including some of the crystalline ones, using a unified framework of hybrid Wannier functions. I will also show how the same methods can be used to identify topological semimetals.
