Color Duality in Photons - an APS Highlight of the Year 2016

The paper “Ramsey Interference with Single Photons”[1] and accompanying Viewpoint “Photon Qubit is Made of Two Colors”[2] have been selected as one of the Highlights of the Year 2016 by APS Physics. It was co-authored by Dr. Sven Ramelow, who recently started his Emmy-Noether-Group at the Institute for Physics, Humboldt-University Berlin, and is associated with IRIS Adlershof. While there have numerous highly interesting papers in Physical Review Letters in 2016, APS Physics explains their selection, writing: “It’s no surprise that LIGO’s discovery of gravitational waves tops our list of favorite Physics stories in 2016. The other slots went to research that marked a change in perspective, demonstrated an impressive experimental feat, or simply made us think.”
Incidentally, Dr. Sven Ramelow is working on follow-up ideas and experiments of this paper, which he looks forward to soon being implemented at the HU Physics Department and at  IRIS Adlershof and yielding new intriguing results.

Prof. Christoph T. Koch and Prof. Nicola Pinna new members at IRIS Adlershof

Christoph T. Koch (photo left), professor for structural research and electron microscopy at Humboldt-Universität's physics department and Nicola Pinna, professor for functional materials at the department of chemistry of Humboldt-Universität zu Berlin are new members at IRIS Adlershof. Christop Koch's research focuses on the development of new methods in quantitative transmission electron microscopy (TEM) and their application to materials science problems. Nanostructured materials are in the focus of Nicola Pinna's research interests. Special emphasis is laid on the synthesis of novel multifunctional materials, their characterization and the study of their physical properties. IRIS Adlershof would like to congratulate both new members and is looking very much forward to a fruitful collaboration.
