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…
Parquet approximation for molecules: spectrum and optical conductivity of the Pariser-Parr-Pople model
Petra Pudleiner, Patrik Thunström, Angelo Valli +3
We study a simple model system for the conjugated -bonds in benzene, the Pariser-Parr-Pople (PPP) model, within the parquet approximation (PA), exemplifying the prospects of the…
The {\it victory} project v1.0: an efficient parquet equations solver
Gang Li, Anna Kauch, Petra Pudleiner +1
{\it Victory}, i.e. \underline{vi}enna \underline{c}omputational \underline{to}ol deposito\underline{ry}, is a collection of numerical tools for solving the parquet equations for t…
