Computational Quantum Many-Body Physics Group
We are the computational condensed matter physics group at the Physics department of the University of Michigan. We are part of the theoretical Condensed matter physics group at U of M, along with the groups of Kai Sun and Xiaoming Mao.
We work on strongly correlated quantum systems, quantum Monte Carlo, numerical algorithms for strongly correlated many-body systems and quantum many-body theory.
Information about our research, our members, and openings for graduate students and postdocs. We have Graduate student and Postdoc openings for 2015 and beyond!
