Charles Marcus

Charles MarcusCharlie Marcus is a  Professor at the Niels Bohr Institute and Principal Investigator at Microsoft Quantum Lab Copenhagen. He is also a member of the Niels Bohr International Academy. Charlie was raised in Sonoma, California, and studied at Stanford (undergraduate) and Harvard University (PhD). Before coming to Copenhagen in 2011, he also taught Physics at Stanford and Harvard. His research interests have varied over the years, from neural networks as a graduate student to quantum chaos and mesoscopic physics, nanotubes, graphene, nanowires, and more recently quantum information and qubits. Much of his research is now focused on the realization of non-abelian excitations in solid state systems, including superconductor-semiconductor hybrid structures and fractional quantum Hall systems. Charlie lives with his wife and two children in Central Copenhagen.

Karsten Flensberg works in the research group Solid State Physics and is a co-founder of Center for Quantum Devices (QDev). He is the director of QdevKarsten Flensberg works with theoretical many-body and solid-state physics in relation to quantum mechanic effects on nanostructures and superconductors - especially in context of quantum information systems and electron transport in molecular transistors and quantum dots.

My activities cover mainly carbon nanomaterials and semiconductor nano wires grown in-house. When turned into electronic devices they enable investigations and control of quantum phenomena, our core QDev activity. Progress relies on the ability to optimise the microstructure of materials and interfaces, thus we keep one foot in materials science. Interestingly, our devices can also be useful in biosensing,  molecular electronics and photovoltaics – we pursue some of these applications in the Nano-Science Center. My teaching covers quantum transport and solid state physics.

I work on theoretical many-body physics, with a strong emphasis on correlated electrons in solid state systems. This includes problems of quantum transport either in bulk materials or through low-dimensional nano-junctions such as wires, dots and single molecules. The intricate interplay between correlation, and non-equilibrium effects remains a central theme in my research, a good part of which is rooted in the experimental QDev activities.

 I am an associate professor working with experimental low temperature quantum transport at the Center for Quantum Devices. My research focuses on the physics of semiconductor nanowires couples to superconductors and on mesoscopic phenomena in strongly correlated electron systems emerging at the interfaces of complex oxide heterostructures.

Ferdinand Kuemmeth

My focus centers on practical quntum design and cryogenic electric manipulation and readout techniques. By choosing the material, geometry and boundary conditions, we create nanodevices with well/controlled, often surprising spin-electronic properties. Low-dimensional semiconductors such as nanowires and 2D electron gases challenge us to haness the role of spin-orbit coupling, type of confinement, and the interplay between conduction band, valence bands, and superconductivity.

If the twentieth century was about discovering the quantum mechanical laws that govern our universe, then the 21st century is about pushing the boundaries, and finding out want these laws allow  us to do. I am interested in the dynamics of quantum many-body systems, in particular those which are driven far from equilibrium. This regime opens possibilities for quantum control and for the discovery of new emergent many-body phenomena unlike anything known for equilibrium systems.
