Pomeranchuk and other Instabilities in the t-t' Hubbard model at the Van Hove Filling
V. Hankevych, I. Grote, F. Wegner
We present a stability analysis of the two-dimensional t-t' Hubbard model for various values of the next-nearest-neighbor hopping t', and electron concentrations close to the Van H…

Stability Analysis of the Hubbard-Model
I. Grote, E. Koerding, F. Wegner
An effective Hartree-Fock-Bogoliubov-type interaction is calculated for the Hubbard-model in second order in the coupling by means of flow-equations. A stability analysis is perfor…
