Functional Callan-Symanzik equation
Jean Alexandre, Janos Polonyi
We describe a functional method to obtain the exact evolution equation of the effective action with a parameter of the bare theory. When this parameter happens to be the bare mass…

Magnetic catalysis in QED_3 at finite temperature: beyond the constant mass approximation
J. Alexandre, K. Farakos, G. Koutsoumbas
We solve the Schwinger-Dyson equations for (2+1)-dimensional QED in the presence of a strong external magnetic field. The calculation is done at finite temperature and the fermioni…

Vacuum polarization in thermal QED with an external magnetic field
Jean Alexandre
The one-loop vacuum polarization tensor is computed in QED with an external constant, homogeneous magnetic field at finite temperature. The Schwinger proper-time formalism is used…
