Effects of the Van Hove singularities on magnetism and superconductivity in the t-t' Hubbard model: a parquet approach

V. Yu. Irkhin, A. A. Katanin, M. I. Katsnelson

The t-t' Hubbard model for the Fermi level near the Van Hove singularity is considered within the renormalization group and parquet approaches. The interplay of ferromagnetic, anti…
