Fermionic contributions to the free energy of noncommutative quantum electrodynamics at high temperature

We consider the fermionic contributions to the free energy of noncommutative QED at finite temperature T. This analysis extends the main results of our previous investigation where we have considered the pure bosonic sector of the theory. For large values of θT2 (θ is the magnitude of the noncommutative parameters) the fermionic contributions decrease the value of the critical temperature, above which there occurs a thermodynamic instability.
