We have applied the Microcanonical Fermionic Average method to QED_2, i.e. the Schwinger Model, to test its applicability to Asymptotically Free Theories. We present here the results of the simulations, compared to the continuum results. Since the M.F.A. method allows the study of the whole $\beta, m_f$ plane at very small computer cost, we are able to verify the scaling of the chiral condensate at high degree, and obtain the continuum result within 3 decimal places.

Abstract
We have applied the Microcanonical Fermionic Average method to QED_2, i.e. the Schwinger Model, to test its applicability to Asymptotically Free Theories. We present here the results of the simulations, compared to the continuum results. Since the M.F.A. method allows the study of the whole $\beta, m_f$ plane at very small computer cost, we are able to verify the scaling of the chiral condensate at high degree, and obtain the continuum result within 3 decimal places. We present also results for the plaquette energy.File in questo prodotto:
