Abstract:
In this paper a method previously employed by Salmhofer to establish
an exact equivalence of the oneflavour strong
coupling lattice Schwinger model with Wilson fermions to some 8vertex
model is applied to the case with two flavours.
As this method is fairly general and can be applied to strong coupling QED
and purely fermionic models with any
(sufficiently small) number of Wilson fermions in any dimension
the purpose of the present study is mainly a methodical
one in order to gain some further experience with it. In the paper the
vertex model equivalent to the twoflavour strong
coupling lattice Schwinger model with Wilson fermions is found. It turns
out to be some modified 3state 20vertex
model on the square lattice, which can also be understood as a regular
6state vertex model. In analogy with the oneflavour
case, this model can be viewed as some loop model.
