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.
Our group is now part of the Erwin Schrödinger Center for Quantum Science & Technology (ESQ), which is an Austria-wide postdoc and discovery programme dedicated to highly innovative research. Funding comes from the Austrian Federal Ministry of Education, Science and Research (BMBWF) and the coordination is carried out by the Austrian Academy of Sciences (ÖAW).
A new paper with our collaborators in Nice and London just appeared in Nature Photonics and is highlighted in OSA Optics & Photonics News and in Pro-Physik. In this work we demonstrate how to design the optimal wave front to deliver the highest possible force or torque onto a target embedded in a complex environment (see illustration on the left for a wave field transferring a strong torque onto a square target).
A joint work with Hasan Yılmaz and the group of Hui Cao just appeared in Physical Review Letters. We show that high-transmission channels in disordered media have an increased range of the angular memory-effect.
