Vacuum polarization in thermal QED with an external magnetic field
Abstract
The oneloop vacuum polarization tensor is computed in QED with an external, constant, homogeneous magnetic field at finite temperature. The Schwinger propertime formalism is used and the computations are done in Euclidian space. The wellknown results are recovered when the temperature and/or the magnetic field are switched off and the effect of the magnetic field on the Debye screening is discussed.
