This seminar series is jointly organized by EP2, EP3, EP4, TP4 and TP1. Our aim is to provide a platform to discuss models, methods and material classes where correlations play a dominant role. Special emphasis is placed on correlation effects in surfaces and interfaces with tunable interactions. (FOR1162). We have reserved SE 4 from 15h00-17h00 on Thursdays. We suggest that the invited speakers give a 50 minutes talk followed by a discussion.
