Lukas Janssen (TU Dresden): "Emergence of relativistic flatland fermions in systems without fermions" (ECT* colloquium)

Wednesday 30 Sept 2020, 17:00 → 18:30 Europe/Berlin

Abstract:

Planar fermions occur frequently in layered condensed matter systems. In such materials, the lowered dimensionality typically leads to an enhancement of correlation effects, providing conditions that parallel those of strongly-interacting quark matter. On the one hand, this facilitates quantum simulations of aspects of particle and nuclear physics in table-top experiments. On the other hand, it makes entirely new and unexpected physical phenomena possible. This talk will give an overview of different setups, in which planar fermions arise as effective low-energy excitations. Besides the usual electronic systems that feature relativistic fermions already in the noninteracting limit, also the situation in which Fermi quasiparticles emerge as a consequence of a fractionalization mechanism will be covered.
