Description:
Author(s): F. Grusdt, D. Abanin, and E. Demler We propose an interferometric method to measure Z2 topological invariants of time-reversal invariant topological insulators realized with optical lattices in two and three dimensions. We suggest two schemes which both rely on a combination of Bloch oscillations with Ramsey interferometry and can be ... [Phys. Rev. A 89, 043621] Published Thu Apr 24, 2014
