Stable charged cosmic strings
H. Weigel, M. Quandt, N. Graham
We study the quantum stabilization of a cosmic string by a heavy fermion doublet in a reduced version of the standard model. We show that charged strings, obtained by populating fe…

Gauge Invariance and Vacuum Energies of Non-Abelian String-Configurations
H. Weigel, M. Quandt
We improve on a method to compute the fermion contribution to the vacuum polarization energy of string-like configurations in a non-Abelian gauge theory. We establish the new metho…

Vacuum Energies of Non--Abelian String--Configurations in 3+1 Dimensions
H. Weigel, M. Quandt, N. Graham +1
We develop a method to compute the fermion contribution to the vacuum polarization energy of string--like configurations in a non--abelian gauge theory. This calculation has been h…
