Symmetry-protected nodal phases in correlated electron systems (C07)

• Subject Area: Theoretical Condensed Matter Physics
• Term: since 2015
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 258499086

This project aims to understand the strong-coupling phases of topologically non-trivial band structures, in which electronic correlation effects have opened a spectral gap without the concomitant onset of a long-range order. The physics of topological Mott insulators and of their exotic boundary phenomena are addressed by combining Green’s function methods and non-perturbative calculations of one-particle self-energy as well as two-particle vertex functions.
