Thermodynamical properties of QED in 1+1 dimensions within light front dynamics

Abstract

We investigate thermodynamical properties of quantum electrodynamics in 1+1 dimensions. Discrete light cone quantization is used to compute the partition function of the canonical ensemble and the thermodynamical potential. The potential is evaluated for different system sizes and coupling strengths. We perform the continuum limit and the thermodynamical limit and present basic thermodynamical quantities as a function of temperature for the interacting system. A more accurate estimation of low lying bound state masses at non-perturbative coupling strength are determined due to the higher harmonic resolution.
