Proper-time methods in the presence of non-constant background fields
arXiv:hep-ph/9410393 · doi:10.1007/3-540-59163-X_291
Abstract
A formalism is developed to enable the construction of the effective action and related quantities in QED for the case of time-varying background electric fields. Some examples are studied and evidence is sought for a possible transition to a phase in which chiral symmetry is spontaneously broken. YCTP-P14-94
