Lin Lin: Dynamical Mean-Field Theory: Theory and Algorithms
Diagrammatic Monte Carlo–the use of stochastic methods to evaluate many-body perturbation expansions–is in a period of rapid development, with new methods organizing the perturbation theory and for extending its radius of convergence making new classes of applications possible. The workshop will bring together the leading experts in the subject to compare results and approaches, assess the current status of the field, brainstorm new methods and select key science targets for the coming year.
