Prof. Dr. Johannes Knolle



Academic Career and Research Areas

Professor Knolle’s area of expertise is in condensed matter systems in regimes in which the laws of quantum mechanics are important. In condensed matter physics, complex behaviour arises from the interaction of a large number of basic degrees of freedom. The objective of his research is to uncover the richness of this fascinating behaviour, and to understand the universal principles that organize the physical world. Knolle’s research is focused on the search for unconventional quantum phases in correlated materials, which does not only lead to a deeper understanding of the fundamental principles driving these phases but has also practical relevance for future quantum technology.

Professor Knolle studied Physics at the Technical University Dresden and Boston University. He completed his PhD at the Max Planck Institute for the Physics of Complex Systems in 2014. After a postdoctoral position at the University of Cambridge he joined Imperial College London as a Lecturer in 2017. In 2019, he was appointed to an Associate Professorship at TUM.
