Dr. Tim Schröder and Dr. Olaf Hohm, new members at IRIS Adlershof

An essential prerequisite for quantum communication and technology is the transmission of quantum information over long distances, but far-reaching and stable networks can only be realized with quantum amplifiers. Dr. Tim Schröder conducts research on such amplifiers with the ERC project QUERP “Quantum Repeater Architectures Based on Quantum Memories and Photonic Encoding” and also attempts to combine complementary technologies from quantum communication: In a hybrid quantum repeater module, two different concepts, such as quantum memory in tin defect centers in diamond, and photonic cluster states are to be brought together.

Dr. Olaf Hohm leads the ERC Consolidation Group “Symmetries and Cosmology”. He‘s developing a computational approach based on string theory, arguably the most promising candidate for a complete theory of quantum gravity. This approach might answer questions relating to the very early history of the Universe, and even test string theory on measurements of background radiation.

IRIS Adlershof welcomes its new members warmly and looks forward to a long and fruitful cooperation.


"Étoiles de l'Europe 2019" - iSwitch receives prestigious award from the French Ministry of Higher Education, Research and Innovation

The Innovative Training Network iSwitch is awarded the "Étoiles de l'Europe" prize of the French Ministry of Higher Education, Research and Innovation for its outstanding and European-oriented research. With this, the project, in which  IRIS Adlershof members Prof. Norbert Koch and Prof. Stefan Hecht were participating as Principle Investigators, now literally belongs to the shining "stars of Europe".

The award is given each year to twelve research and innovation projects initiated in France to reward and strengthen international cooperation in the field of science and technology at a European level. iSwitch was coordinated by Paolo Samorì, Professor at the University of Strasbourg, and since 2015 has brought together leading international research groups at the interface between chemistry, physics and engineering with the aim of educating and promoting the next generation of researchers in the emerging fields of materials science and nanoscience. The network consisted of 14 interdisciplinary academic and industrial partners from seven European countries (France, Germany, Belgium, Spain, Italy, Great Britain and Switzerland).

In December 2018, the project funded by the EU under Horizon2020 ended successfully: The iSwitch training program qualified its young scientists for employment with leading global companies such as Johnson & Johnson, universities of excellence or prestigious research institutions. In addition, the knowledge gained and technologies developed in the project have provided significant impetus in the research field of optoelectronic devices, for example for the manufacture of artificial retinae and smart textiles such as special clothing, which can measure temperature changes and then adapt shape and color.

IRIS Adlershof congratulates the iSwitch team for this great success!


DFG funds new Research Training Group „Rethinking Quantum Field Theory“

The Research Training Group (RTG) "Rethinking Quantum Field Theory" is based in the Physics Department and the IRIS Adlers­hof of Humboldt-Universität zu Berlin(HU). From April 2020, it will be funded by the German Research Foundation (DFG) for four and a half years with about 4 Mio Euro. The RTG will address urgent theoretical questions and significant innovations in quantum field theory (QFT) that go beyond established methods.

Quantum field theory (QFT), the unification of quantum mechanics and special relativity, represents a major intellectual achievement of the past century. These innovations culminated in the formulation of the Standard Model (SM). With the discovery of the Higgs boson, the SM is an empirical validated and mathematically consistent theory valid up to highest energies. However, a number of terrestrial experiments exhibit significant tensions with the SM, while astrophysical observations require the existence of dark matter and energy showing that the SM is not the ultimate theory of particle physics. In addition, pressing theoretical issues as the quest for a quantum theory of gravity, the hierarchy problem and the discovery of dualities between different QFTs raise questions about the foundations of the SM and QFT in general. In recent years important innovations in QFT occurred leading the community to a serious rethinking of its core concepts. These include the methodology of perturbation theory, dualities and hidden symmetries, the prominent role of effective field theory in fundamental physics, modern on-shell methods for scattering amplitudes and the gradient flow methodology in lattice field theory. The further development of these methods and concepts of modern QFT leading to a deep rethinking of it provides the common basis of this proposed research training group (RTG). We designed a timely qualification program for the new generation of quantum field theorists. The RTG is headed by 12 principal investigators including senior and junior research group leaders, encompassing all groups working in theoretical high energy physics Humboldt University. Partners of the RTG are the Max-Planck-Insitute for Gravitational Physics and the Helmholtz Center DESY. IRIS Adlers­hof is involved with several members in the newly established RTG. These are RTG-spokesman Prof. Jan Plefka, Dr. Valentina Forini, Prof. Dirk Kreimer and Prof. Matthias Staudacher.

IRIS Adlers­hof congratulates the successful applicants and wishes a lot of success.
