Truncated Unity Parquet Solver
Christian J. Eckhardt, Carsten Honerkamp, Karsten Held +1
We present an implementation of a truncated unity parquet solver (TUPS) which solves the parquet equations using a truncated form-factor basis for the fermionic momenta. This way f…
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…
Competition between antiferromagnetic and charge density wave fluctuations in the extended Hubbard model
Petra Pudleiner, Anna Kauch, Karsten Held +1
By extending our {\it victory} implementation of the parquet approach to include non-local Coulomb interactions, we study the extended Hubbard model on the two-dimensional square l…
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…
