Efficient implementation of the parquet equations -- role of the reducible vertex function and its kernel approximation
Gang Li, Nils Wentzell, Petra Pudleiner +2
We present an efficient implementation of the parquet formalism which respects the asymptotic structure of the vertex functions at both single- and two-particle levels in momentum-…

Interacting bosons in two-dimensional flat band systems
Petra Pudleiner, Andreas Mielke
The Hubbard model of bosons on two dimensional lattices with a lowest flat band is discussed. In these systems there is a critical density, where the ground state is known exactly…
