Exact ground states of generalized Hubbard models
Jan de Boer, Andreas Schadschneider
We present a simple method for the construction of exact ground states of generalized Hubbard models in arbitrary dimensions. This method is used to derive rigorous criteria for th…
Criticality in Simple Models of Evolution
Jan de Boer, A. D. Jackson, Tilo Wettig
We consider two, apparently similar, models of biological evolution which have been claimed to exhibit self-organized critical behaviour. A careful reanalysis of these models, incl…
-pairing as a mechanism of superconductivity in models of strongly correlated electrons
Jan de Boer, Vladimir E. Korepin, Andreas Schadschneider
We consider extended versions of the Hubbard model which contain additional interactions between nearest neighbours. In this letter we show that a large class of these models has a…
