Supercurrent interference in HgTe Josephson junctions
Wolfgang Himmler, Ralf Fischer, Michael Barth +8
Wires made of topological insulators (TI) are a promising platform for searching for Majorana bound states. These states can be probed by analyzing the fractional ac Josephson effe…

Terahertz photogalvanics in twisted bilayer graphene close to the second magic angle
M. Otteneder, S. Hubmann, X. Lu +6
We report on the observation of photogalvanic effects in twisted bilayer graphene (tBLG) with a twist angle of 0.6°. We show that excitation of tBLG bulk causes a photocurrent, who…
