Electric-Magnetic Duality in QED Effective Action
W. S. Bae, Y. M. Cho, D. G. Pak
Recently we have obtained a non-perturbative but convergent series expression of the one loop effective action of QED, and discussed the renormalization of the effective action. In…
A Non-perturbative Estimate of Vacuum Polarization in QED
Y. M. Cho, D. G. Pak
We present a new estimate of the fine structure constant and the -function of QED at an arbitrary scale. Using the non-perturbative but convergent series expression of the one l…
Effective Action - A Convergent Series - of QED
Y. M. Cho, D. G. Pak
The one-loop effective action of QED obtained by Euler and Heisenberg and by Schwinger has been expressed by an asymptotic perturbative series which is divergent. In this letter we…
Dynamical Symmetry Breaking and Magnetic Confinement in QCD
Y. M. Cho, D. G. Pak
We present a gauge independent method to construct the effective action of QCD, and calculate the one loop effective action of QCD in an arbitrary constant background field…
