  We investigate thermodynamic properties of quantum electrodynamics in 1+1
dimensions (QED$_{1+1}$) utilizing light front dynamics. Therefore we derive
the partition function of the canonical ensemble in discrete light cone
quantization, and calculate the thermodynamical potential. This central
quantity is evaluated for different system sizes and coupling strengths. We
investigate the continuum limit and the thermodynamical limit and present basic
thermodynamical quantities such as pressure, energy, and entropy, as a function
of temperature for the interacting system. The results are compared to the
ideal bosonic and fermionic cases.
