Together with a team from the Walther Meißner Institute and TU Munich, we showed in a recent Letter that the conventional Hahn echo pulse sequence from electron spin resonance produces a train of periodic, self-stimulated echoes when the involved spins are strongly coupled to a resonator. See discussions of this work on ChemEurope and on the websites of the Austrian Press Agency and TU Munich.
Michael Fraller, Maximilian Geismann and Markus Kaczvinszki successfully defended their Master theses – congratulations from all of us!
In a new paper with Kostas, Ivor and Andre, we demonstrate how a dielectric medium can be made invisible for certain incoming beams when a suitable spatial distribution of gain and loss is added to the medium’s permittivity. (See highlight in Optica top downloads.)
An image produced by Matthias Kühmayer for our recent work on optimal wave control was chosen as the header for the March online issue of Nature Photonics.
