Phase diagram of the one-dimensional extended Hubbard model with attractive and/or repulsive interactions at quarter filling
Karlo Penc, Frederic Mila
We study the phase diagram of the one dimensional (1D) model at quarter filling in the most general case where the on-site and first-neighbour interactions and can be…

Phase diagram of the one-dimensional extended Hubbard model at quarter filling
Frederic Mila, Xenophon Zotos
We used exact diagonalization of small clusters and exact results in various limits to determine the phase diagram and the critical exponents of the one dimensional (1D) mode…

Poisson versus GOE statistics in integrable and non-integrable quantum hamiltonian
Didier Poilblanc, Timothy Ziman, Jean Bellissard +2
We calculate the level statistics by finding the eigenvalue spectrum for a variety of one-dimensional many-body models, namely the Heisenberg chain, the t-J model and the Hubbard m…
