Workshop on diagrammatic Monte-Carlo
- Organized by
-
Antoine Georges, Ph.D.Director, Center for Computational Quantum Physics, Flatiron Institute -
Andrew Millis, Ph.D.CCQ Co-Director, Flatiron Institute -
Angel Rubio, Ph.D.Co-Director, Initiative for Computational Catalysis, Flatiron Institute
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.
