William Witczak-Krempa is interested in materials that display quantum properties at low temperatures. For example, some materials lose electrical resistance and become superconductors, which have important practical applications, from lossless electricity transmission to the manufacture of extremely powerful magnets.
However, low temperatures limit large-scale production. Could quantum materials be created at higher temperatures and be made more accessible to humans? William Witczak-Krempa’s team is tackling the question using a variety of mathematical and numerical tools, including artificial intelligence.
Understanding matter at the quantum level is essential for, among other things, the creation of a quantum computer, the device physicists and computer scientists dream of. Its computing power would far exceed that of any existing computer.
William Witczak-Krempa came to the University of Montreal after completing two postdoctoral fellowships, one at the Perimeter Institute in Waterloo and the other at Harvard University. He is the Canada Research Chair in Quantum Phase Transitions and a member of the Regroupement québécois sur les matériaux de pointe (RQMP), and the Centre de recherches mathématiques (CRM).
