Topological index for periodically driven time-reversal invariant 2D systems
David Carpentier, Pierre Delplace, Michel Fruchart +1
We define a new -valued index to characterize the topological properties of periodically driven two dimensional crystals when the time-reversal symmetry is enforced. This inde…

Parallel Transport and Band Theory in Crystals
Michel Fruchart, David Carpentier, Krzysztof Gawędzki
We show that different conventions for Bloch Hamiltonians on non-Bravais lattices correspond to different natural definitions of parallel transport of Bloch eigenstates. Genericall…
