Abstract

The pinning of the Fermi level to the Van Hove singularity and the formation of flat bands in the two-dimensional [Formula presented] Hubbard model is investigated by the renormalization group technique. The “Van Hove” scenario of non-Fermi-liquid behavior for high-[Formula presented] compounds can take place in a broad enough range of the hole concentrations. The results are in qualitative agreement with the recent angle-resolved photoemission spectroscopy data on [Formula presented].
