The Schwinger model on the lattice in the Microcanonical Femionic Average Approach

The Microcanonical Fermionic Average method has been used so far in the context of lattice models with phase trantitions at finite coupling. To test its applicability to Asymptotically Free theories, we have implemented it in QED_2, i.e. the Schwinger Model. We exploit the possibility, intrinsic to this method, of studing the whole \β,m plane at negligible computer cost, to follow constant physics trajectories and measure the m \→ 0 limit of the chiral condensate. We recover the continuum result within 3 decimal places.
