Topological insulators - A challenge for theory

Topological insulators have become a very hot topic in condensed matter physics.
These new classes of materials host - while insulating in the bulk - linearly dispersing
and topologically protected electronic states with a unique spin texture at their surfaces.
Their rich properties, attributed to spin-orbit induced band inversions, are fascinating
with respect to both fundamental research and device applications.
In this seminar I shall give an overview of theoretical results, from fundamental
properties to direct links to experiment. I will address topological invariants,
first-principles calculations for the Dirac surface state of the Z2 topological insulator
Bi2Te3, and calculated photoemission intensities.
