Schwinger model chiral anomaly
WebSchwinger model In the Schwinger model at finite temperature, we derive a closed form result for the chiral anomaly which arises from the long distance behavior of the electric … WebTwo closely related topological phenomena are studied at finite density and temperature. These are chiral anomaly and Chern–Simons term. It occurs that the chiral anomaly doesn’t depend on density and temperature. Cher…
