Abstract
We discuss a short-range order mechanism for understanding pseudogap physics of cuprates in which the competition between a variety of magnetic orders frustrates the development of the long-range order. We show in particular that the competition between the effects of Van Hove singularity nesting and conventional Fermi surface nesting leads to a material-dependent transition between Mott and Slater physics, and the emergence of a spin-frustrated state in the crossover region.
