On Debye Mass in Hot Dense QED

  • Starting from the Schwinger-Dyson equation for the photon propagator in QED, we derive a useful relation between the Debye mass and the thermodynamic pressure. Using this relation, we calculate the two-loop Debye mass from relevant pressures at finite temperature and chemical potential. The result indicates that the two-loop correction decreases the Debye screening mass. We also discuss the magnetic mass in QED plasma.

Abstract: Starting from the Schwinger-Dyson equation for the photon propagator in QED, we derive a useful relation between the Debye mass and the thermodynamic pressure. Using this relation, we calculate the two-loop Debye mass from relevant pressures at finite temperature and chemical potential. The result indicates that the two-loop correction decreases the Debye screening mass. We also discuss the magnetic mass in QED plasma.
