André-Marie Tremblay Theoretical condensed matter physicist

In recent years, Tremblay and his team have developed “Quantum Cluster Approaches” that allow them to obtain phase diagrams that are in surprisingly good agreement with experiment not only for high temperature superconductors, but also for layered organics and other materials described by the same class of models. Much of his research is on high temperature superconductors and layered organic superconductors.  André-Marie Tremblay and his team have also been involved in developing new analytical methods to understand the new phenomena observed in strongly correlated electron systems. They test the validity of these methods with the help of numerical Quantum Monte Carlo simulations, and use the new analytical methods to obtain theoretical predictions. In particular, predictions for electron-doped cuprates have been successfully compared with experiments. He is one of the co-discoverers of multifractals. He says his CIFAR affiliation gave him the initial impetus, confidence and networking necessary to enter this competitive field and allowed him to persevere and stay in the major leagues of research.
