Stability analysis of non-Abelian electric fields (2207.05102v1)
Published 11 Jul 2022 in hep-th, hep-lat, and hep-ph
Abstract: We study the stability of fluctuations around a homogeneous non-Abelian electric field background that is of a form that is protected from Schwinger pair production. Our analysis identifies the unstable modes and we find a limiting set of parameters for which there are no instabilities. We discuss potential implications of our analysis for confining strings in non-Abelian gauge theories.
