We demonstrated for the first time coherent excitation of the octupole transition near 467nm in a single 172Yb+ ion, which is a core requirement for a scalable test of Local Lorentz invariance using the electronic F-state manifold.  The large degree of control over the magnetic environment and laser...

Topological defects in low-dimensional nonlinear systems feature a sliding-to-pinning transition of relevance for a variety of scenarios, ranging from biophysics to nano- and solid-state physics. We find that the dynamics after a local excitation results in a highly nontrivial energy transport in...
