Parquet dual fermion approach for the Falicov-Kimball model
Katharina Astleithner, Anna Kauch, Tin Ribic +1
In the Falicov-Kimball model, a model for (annealed) disorder, we expect weak localization corrections to the optical conductivity. However, we get such weak localization effects o…

Generic optical excitations of correlated systems: -tons
Anna Kauch, Petra Pudleiner, Katharina Astleithner +3
The interaction of light with solids gives rise to new bosonic quasiparticles, with the exciton being---undoubtedly---the most famous of these polaritons. While excitons are the ge…
