A simple statistical system simulating dynamical ferminns in the strong coupling limit

Abstract

It is shown, that in the strong coupling limit a system of dynamical fermions interacting via U(1)-gauge fields is equivalent to a system of vectors, which live on the odd sites and point on the even sites of a cubic lattice. Preliminary results for the chiral condensate and Wilson loop expectation values at β = 0 are presented. The latter appear as coefficients in a loop expansion of the fermionic determinant, which can be used to go beyond the quenched approximation. © 1988.
