Many-chain Generalization of Gauge-Coupled Fermionic Systems

H. J. Schulz, B. S. Shastry

We present a many chain generalization of a recent work of ours, wherein an arbitrary number of fermionic chains are coupled via a Gauge interaction. Central to this construction i…

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 $J_{1}$ -- $J_{2}$ Heisenberg Antiferromagnet

T. Einarsson, H. J. Schulz

We calculate the spin stiffness $ρ_{s}$ for the frustrated spin- $\frac{1}{2}$ Heisenberg antiferromagnet on a square lattice by exact diagonalizations on finite clusters of up to $36…
