Roger Mong received his BS in Engineering Physics from University of Toronto and his Ph.D. in Physics from University of California, Berkeley in 2012, where he studied topological insulators and superconductors. He then took a postdoctoral appointment at Caltech, pursuing research in the fractional quantum Hall effect. He joined the Department of Physics at the University of Pittsburgh in 2015.
I work in condensed matter theory and quantum information, specializing in characterization of topological phases, classical simulation of quantum systems, quantum material design, and quantum control.
In contrast to Landau’s symmetry classification of matter, where phases are described by symmetry-breaking order parameters, topological phases are distinguished by nonlocal topological invariants. These phases are fundamentally quantum mechanical with no classical analogue; they are characterized by exotic emergent excitations of the bulk, which are often accompanied by gapless edge degrees of freedoms. My research is focused on finding materials which support these phases of matter, understanding their properties, and exploring ways that these systems can be manipulated.
