Enhanced preheating after multi-field inflation: on the importance of being special
Enhanced preheating after multi-field inflation: on the importance of being special
We discuss preheating after multi-field inflation in the presence of several preheat matter fields that become light in the vicinity of (but not at) the inflatons' VEV, at distinct extra-species-points (ESP); this setup is motivated by inflationary models that include particle production during inflation, e.g. trapped inflation, grazing ESP encounters …
