The higher density-of-states around the Fermi level translates into a narrower effective band-width the quasi-particles experience at low energies. In consequence, the gamma-sheet (that of the widest band but with a van-Hove singularity nearby) electrons are renormalized most. The influence of van-Hove singularities has recently been investigated in several model studies (see e.g. Refs in the paper) and in Sr2RuO4 this influence is realized.Anonymousnoreply@blogger.com
