Benjamin Béri studies novel forms and properties of quantum matter, mostly in the realm of condensed matter physics. His current research focuses on topological phases, with interests that include using many-body theory to devise schemes for creating and detecting such phases in experiments, and exploring their quantum information related features both for fundamental characterisation and information processing applications.
