In this work, we investigate the properties of the Abelian gauge vector
field in the background of a string-cigar braneworld. Both the thin and
thick brane limits are considered. The string-cigar scenario can be
regarded as an interior and exterior string-like solution. The source
undergoes a geometric Ricci flow which is related to a variation of the
bulk cosmological constant. The Ricci flow changes the width and
amplitude of the massless mode at the brane core and recovers the usual
string-like behavior at large distances. By means of suitable numerical
methods, we attain the Kaluza-Klein (KK) spectrum for the string-like
and the string-cigar models. For the string-cigar model, the KK modes
are smooth near the brane and their amplitude are enhanced by the brane
core. Furthermore, the analogue Schrodinger potential is also regulated
by the geometric flow. (C) 2015 The Authors. Published by Elsevier B.V.
