Measuring topology by dynamics: Chern number from linking number
Matthias Tarnowski, F. Nur Ünal, Nick Fläschner +4
Integer-valued topological indices, characterizing nonlocal properties of quantum states of matter, are known to directly predict robust physical properties of equilibrium systems.…
Observation of topological Bloch-state defects and their merging transition
Matthias Tarnowski, Marlon Nuske, Nick Fläschner +6
Topological defects in Bloch bands, such as Dirac points in graphene, and their resulting Berry phases play an important role for the electronic dynamics in solid state crystals. S…
Investigation of Feshbach Resonances in ultra-cold 40 K spin mixtures
Jasper S. Krauser, Jannes Heinze, S. Götze +7
Magnetically-tunable Feshbach resonances are an indispensable tool for experiments with atomic quantum gases. We report on twenty thus far unpublished Feshbach resonances and twent…
