The Electronic Structure Discussion Group (ESDG) is a regular informal meeting of researchers from various Cambridge University departments (and several commutable universities in London) who are involved in research into computational electronic structure theory. It has been organized (mostly) by Mike Towler since 2001. ESDG meetings are intended to promote the exchange of ideas between scientists who develop or use techniques such as density functional theory, quantum Monte Carlo, or quantum chemistry methods. This page contains a listing of all talks ever given, many of which have the original talk slides for you to read. Enjoy!
