Gapless topological phases (A02)

• Subject Area: Theoretical Condensed Matter Physics
• Term: since 2016
• Project identifier: Deutsche Forschungsgemeinschaft (DFG) - Project number 277101999

Project A02 considers the topology paradigm in the strongly spin-orbit entangled gapless phases such as Weyl or nodal-line semimetals. It encompasses abstract theoretical questions concerning the classification of such phases with theoretical studies of transport properties and combined theoretical/ experimental studies of boundary signatures of the nontrivial topology. A particular emphasis is placed on Weyl semimetals with spatial inhomogeneities, which enter a phase in which phenomena normally associated with the boundary dominate the bulk.
