Theory of Quantum Matter (TQM)

Our research concentrates on fundamental properties of matter.
Aalto University/Theory of Quantum Matter

Our goal is to explore, predict and design novel phases of matter where quantum mechanics play a key role. We are also working with experimental people to carry out our visions. Our research philosophy is that of theoretical physics -- we employ modern tools of quantum many-body theory and transport theory, though we are no strangers to numerics. Our main efforts are focused on the theory of topological matter <http://www.paneuropeannetworkspublications.com/ST16/#64>, including topological metals, insulators and superconductors. The field of topological matter, having rapidly achieved a central status in contemporary condensed matter physics, combines concepts across the board from solid-state theory to particle physics.  Realizations of topological matter hold promise in revolutionarizing quantum information and nanoelectronics in the future.
