Falicov-Kimball Models: A Partial Review of the Ground States Problem
Christian Gruber
In this review we present a biased review of the ground state properties of the Falicov-Kimball models in 1,2 and infinite dimensions, considering either fermions or hard-core boso…

A remark on off-diagonal long range order
C. A. Piguet, D. F. Wang, C. Gruber
In this work, we study some general property of a strongly correlated electron system defined on a lattice. Assuming that the lattice system exhibits off-diagonal long range order,…
One Dimensional Lattice Models of Electrons with 1/r^2 Hopping and Exchange
Ch. Gruber, D. F. Wang
This talk reviews some recent progresses in the studies of low dimensional electronic models of strong correlations.
One dimensional exactly solvable models of strongly correlated electrons of hopping and exchange
C. Gruber, D. F. Wang
We review some recent progresses in study of the 1D strongly correlated electron systems of long range hopping and exchange. The systems are completely integrable, with infinite nu…
