Vector profile and gauge invariant observables of string field theory solutions for constant magnetic field background

Journal of High Energy Physics volume 2018, Article number: 144 (2018) Cite this article

Abstract

We study profiles and gauge invariant observables of classical solutions corresponding to a constant magnetic field on a torus in open string field theory. We numerically find that the profile is not discontinuous on the torus, although the solution describes topologically nontrivial configurations in the context of low energy effective theory. From the gauge invariant observables, we show that the solution provide correct couplings of closed strings to a D-brane with constant magnetic field.
