A new class of exactly solvable interacting fermion models in one dimension
H. J. Schulz, B. S. Shastry
We investigate a model containing two species of one-dimensional fermions interacting via a gauge field determined by the positions of all particles of the opposite species. The mo…

Direct Calculation of the Spin Stiffness in the -- Heisenberg Antiferromagnet
T. Einarsson, H. J. Schulz
We calculate the spin stiffness for the frustrated spin- Heisenberg antiferromagnet on a square lattice by exact diagonalizations on finite clusters of up to $36…
