Theory and Methods

The quantum many-body problem is one of the hard problems of complexity theory: a direct solution requires computational resources growing exponentially with the size of the problem to be solved.

At CCQ we are developing, optimizing, and benchmarking sophisticated algorithms to make the many-body problem tractable. Our group has expertise in a range of complementary methods including tensor networks, diagrammatic Monte Carlo, dynamical mean field, density functional, wave function and and other methods enabling qualitatively new progress on this grand challenge problem.
