TL;DR
This paper investigates quantum effects in four-dimensional quantum electrodynamics with an additional compactified dimension, focusing on vacuum polarization and parity breaking induced by magnetic flux in a non-trivial gauge vacuum.
Contribution
It provides the first exact calculation of vacuum polarization and parity breaking effects in $QED_{3+1}$ with an extra compactified dimension and magnetic flux.
Findings
Derived the vacuum polarization tensor in this setup.
Calculated the exact parity breaking term.
Showed effects depend on magnetic flux and compactification.
Abstract
We evaluate one-loop effects for in the presence of an extra compactified dimension, in a non-trivial vacuum for the gauge field, such that a non-vanishing magnetic flux is encircled along the extra dimension. We obtain the vacuum polarization tensor and evaluate the exact parity breaking term.
