Inaugural lecture “Quantum Mechanics in Low Dimensions“
by Prof. Dr. Christoph Karrasch

In low-dimensional quantum systems, the collective behaviour of electrons leads to interesting emergent phenomena. However, the theoretical description of such a many-body problem is challenging. Professor Christoph Karrasch’s research focuses on the further development of theoretical physics methods for the description of correlated many-body systems (especially tensor networks and renormalisation group techniques). He applies these methods to problems in the areas of transport properties of quantum chains and quantum dots, non-equilibrium phenomena, disorder and topology, correlations in two dimensions, among others. The lecture is intended to give an introductory overview.

About the person
Christoph Karrasch completed his physics studies at the University of Göttingen in 2006 and his doctorate at RWTH Aachen University in 2010. From 2011-2015, he did postdoctoral research at the University of California at Berkeley. Subsequently (2015-2018), he led an Emmy Noether junior research group at the FU Berlin. Since 2019, Christoph Karrasch is Professor at the Institute for Mathematical Physics at TU Braunschweig.

Inaugural lecture “From Digital Communications to Quantum Networks“
by Prof. Dr.-Ing. Eduard Jorswieck

Information and communication technology is an integral part of our lives. We spend large parts of our working and leisure time on digital devices and with digital media. Current communication systems form the backbone of digitalisation and function very reliably. In the first part of the lecture, Professor Eduard Jorswieck explains the fundamental challenges for future communication systems, for example in sixth generation (6G) mobile radio systems, in terms of data rates, energy efficiency, reliability, latency and resilience, and how these are being addressed in current research projects. The second part of the lecture describes a paradigm shift in information and communication technology. The concepts of quantum mechanics open up fundamental new possibilities to realise powerful computer architectures and communication networks. We venture an outlook on the three research areas post-quantum security, quantum-assisted and quantum-computing-assisted communication with a special focus on the distribution of entangled states as a resource in networks and their possible applications.

About the person
Eduard Axel Jorswieck received his diploma as chartered engineer in technical computer science from the TU Berlin in 2000. In 2004, he also received his PhD in information theory of multi-antenna systems from the TU Berlin at the Heinrich Hertz Institute. From 2006 to 2008 he was a Post-Doctoral Fellow and then Assistant Professor at KTH Stockholm, Sweden in the Department of Signal Processing. From 2008-2019 he was Professor of Theoretical Communications Technology at TU Dresden, where he led the EU project SAPHYRE on spectrum and infrastructure sharing from 2010-2012. From 2011-2019 he was project leader in the DFG Collaborative Research Centre Highly Adaptive Energy-Efficient Computing and from 2012-2020 in the Cluster of Excellence cfAED. Since 2019, he is Professor at TU Braunschweig and heads the Information Theory and Communication Systems Group. He is an IEEE Fellow and has been Editor-in-Chief for the Springer EURASIP Journal on Wireless Communications and Networking since 2017. Since 2020, he is Managing Director of the Institute for Communications Technology at TU Braunschweig.
