Correlation effects on the Fermi surface of the two-dimensional Hubbard model
Y. Otsuka, Y. Morita, Y. Hatsugai
Effects of electron correlation on the Fermi surface is investigated for the two-dimensional Hubbard model by the quantum Monte Carlo method. At first, an infinitesimal doping from…

Zero-modes in the random hopping model
P. W. Brouwer, E. Racine, A. Furusaki +3
If the number of lattice sites is odd, a quantum particle hopping on a bipartite lattice with random hopping between the two sublattices only is guaranteed to have an eigenstate at…
