The schwinger model and its axial anomaly
WebbThe Schwinger model results suggest that the high-temperature domain wall exhibits a surprisingly rich structure: it supports a non-vanishing fermion condensate and perimeter law for spacelike Wilson loops, thus mirroring many properties of the strongly coupled … Webbthe Schwinger model is the presence of the chiral anomaly, which is easier to compute than in four dimensions. The axial vector current, which classically is conserved, gets a new term after radiative corrections. Thus, @ j 5 = e 2ˇ F : (1) For good reviews of this …

WebbWe solve the massless Schwinger model exactly in Hamiltonian formalism on Sl. We construct physical states explicitly and its physical consequences, such as the chiral symmetry breaking or the screening of charges, are discussed. We show how charges are getting to be screened with time and show that we cannot understand the screening … WebbN. S.

Therefore, the chiral anomaly is a …
WebbThe axial anomaly in 2 dimensional QED at finite temperature is carefully investigated in the real time formalism in the limit of vanishing fermion mass. We follow the dispersion approach of Dolgov and Zakharov.
