Theoretical Condensed Matter Physics

Welcome to the website of the research unit "Theoretical Condensed Matter Physics" at the Institute of Nanotechnology!

Our research interests center on fundamental phenomena that reveal the beauty of quantum many-body physics on a nanoscale, define the physical properties of quantum materials, and play a key role in the development of quantum technologies. A major portion of our work concerns the interplay of electron-electron interactions, disorder, and topology in the electronic properties of nanostructures, such as quantum dots and quantum wires, thin films and heterostructures, and graphene-based structures. The areas of focus include charge and energy transport, as well as phase transitions, in topological materials and quantum Hall systems, superconductors, and strongly-correlated electron systems.
