SYTS: Symposium Interaction Effects and Correlations in twodimensional Systems - New Challenges for Theory

SYTS 1: Interaction effects and correlations in twodimensional systems - New challenges for theory

Mittwoch, 3. April 2019, 15:00–17:45, H1

The recent theoretical description of low-dimensional solids has been focussing on two-dimensional materials like graphene and the transition metal dichalcogenides. These atomically thin materials bear new challenges for theory because of their material properties, a true two-dimensionality and a high sensitivity to their surrounding. In particular the interaction and correlation effects are fundamentally different from well-established materials. This symposium brings together world-leading theorists to present and exchange ideas about various state-of-the-art methods to foster the research on 2D materials, which will be necessary to understand and guide experiments in this field.
