Abstract

The vacuum polarization tensor in strong external magnetic fields has been evaluated numerically for various strengths of magnetic fields and momenta of photons under the threshold of the e± pair creation. The fitting formula has been obtained which reproduces the calculated results within 10% of error. The proper time method is employed further to obtain the retarded polarization tensor for finite temperature plasmas.
