Gauge invariant quantum backreaction in U(1) axion inflation
Davide Campanella Galanti, Pietro Conzinu, Giovanni Marozzi +1
We evaluate the quantum backreaction due to a gauge field coupled to a pseudo-scalar field driving a slow-roll inflationary stage, the so-called axion inflation. The backreaction i…
