The phase transition in the multiflavour Schwinger model

TL;DR

This paper investigates the multiflavour Schwinger model at finite temperature, demonstrating that it undergoes a second order phase transition at zero temperature through analysis of the chiral condensate.

Contribution

It provides an analytic quantization of the model with boundary conditions, revealing the nature of its phase transition.

Findings

The model exhibits a second order phase transition at T=0.

Chiral condensate analysis supports the phase transition.

Finite-temperature quantization with boundary conditions is established.

Abstract

A summary is given of a quantization of the multiflavour Schwinger model on a finite-temperature cylinder with chirality-breaking boundary conditions at its spatial ends, and it is shown that the analytic expression for the chiral condensate implies that the theory exhibits a second order phase transition with $T_c = 0$.
