Self-energy correction to energy levels of highly charged ions in a path integral formalism
Sreya Banerjee, Zoltán Harman
Self-energy corrections to the energy levels of bound electrons are calculated in the framework of path integrals. We arrive at the full fermion propagator, using methods of functi…

Vacuum polarization correction to atomic energy levels in the path integral formalism
Sreya Banerjee, Zoltán Harman
Vacuum polarization corrections to the energy levels of bound electrons are calculated using a perturbative path integral formalism. We apply quantum electrodynamics in a framework…

Path integral formalism for the free Dirac propagator in spherical coordinates
Sreya Banerjee, Zoltán Harman
The relativistic Green's function of a free spin-1/2 fermion is derived using the Feynman path integral formalism in spherical coordinates. The Green's function is reduced to an ex…
