André-Marie Tremblay is a theoretical condensed matter physicist.

In recent years, he and his team have developed ‘Quantum Cluster Approaches.’ These 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 Tremblay’s research is on high temperature superconductors and layered organic superconductors. He 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.

Tremblay is one of the co-discoverers of multifractals. He says his CIFAR affiliation gave him the initial impetus, confidence and network necessary to enter this competitive field, and has allowed him to persevere and stay in the major leagues of research.
