Gauge and gravitational instantons: from 3-forms and fermions to weak gravity and flat axion potentials

Gauge and gravitational instantons: from 3-forms and fermions to weak gravity and flat axion potentials

Abstract We investigate the role of gauge and gravitational instantons in the context of the Swampland program. Our focus is on the global symmetry breaking they induce, especially in the presence of fermions. We first recall and make more precise the description of the dilute instanton gas through...
