Michael Knap is working in the field of condensed matter theory. His research is driven by the quest for unconventional quantum phases of matter in strongly correlated many-body systems, both in and out of thermal equilibrium. Interactions and correlations in condensed matter systems often manifest in striking and novel properties. These properties emerge from collective behavior of the quantum particles. To understand the role of interactions between such quantum particles, Michael develops novel numerical approaches based on quantum information theory, utilizes artificial intelligence and machine learning, and develops algorithms for quantum computers.
