In the version of this Article originally published, the affiliation for the author Christian Schneider was mistakenly given as ‘Technische Physik and Würzburg-Dresden Cluster of Excellence ct.qmat, Universität Würzburg, Würzburg, Germany’, but it should have been ‘Institute of Physics, Carl von Ossietzky University, Oldenburg, Germany’. This has now been corrected.
