Effect of Van Hove singularities in the onset of pseudogap states in Mott insulators
Wéi Wú, Mathias S. Scheurer, Michel Ferrero, Antoine Georges
Abstract
This paper studies why doping a Mott insulator does not necessarily lead to a pseudogap in two dimensions. The authors propose a criterion for the appearance of strong-coupling pseudogap in the doped Hubbard model.
