Many-chain Generalization of Gauge-Coupled Fermionic Systems
H. J. Schulz, B. S. Shastry
Abstract
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 is the role of an antisymmetric tensor which enters the couplings and helps define a pseudo-unitary transformation, that maps the models on to ``free fermi'' models with twisted boundary conditions.
