Renormalized perturbation theory for Fermi systems: Fermi surface deformation and superconductivity in the two-dimensional Hubbard model
A. Neumayr, W. Metzner
Divergencies appearing in perturbation expansions of interacting many-body systems can often be removed by expanding around a suitably chosen renormalized (instead of the non-inter…

Reduction formula for fermion loops and density correlations of the 1D Fermi gas
Arne Neumayr, Walter Metzner
Fermion N-loops with an arbitrary number of density vertices N > d+1 in d spatial dimensions can be expressed as a linear combination of (d+1)-loops with coefficients that are rati…

Fermion loops, loop cancellation and density correlations in two dimensional Fermi systems
Arne Neumayr, Walter Metzner
We derive explicit results for fermion loops with an arbitrary number of density vertices in two dimensions at zero temperature. The 3-loop is an elementary function of the three e…
