Analyzing Multi-Field Tunneling With Exact Bounce Solutions
Aditya Aravind, Brandon S. DiNunno, Dustin Lorshbough +1
We study multi-field tunneling using exact solutions for additive potentials. We introduce a binomial potential with non-integer powers that could be considered a generalization of…
Lower Bound for the Multi-Field Bounce Action
Aditya Aravind, Dustin Lorshbough, Sonia Paban
We present a lower bound for the multi-field bounce action with a quartic potential in the absence of gravity. We find that for a large number of fields the lower bound decreases w…
Non-Gaussianity from Excited Initial Inflationary States
Aditya Aravind, Dustin Lorshbough, Sonia Paban
We study squeezed limit generation by excited initial inflationary states in a model independent way. We restrict "excited" to mean a Bogoliubov transformation of the Bunc…
Rapid field excursions and the inflationary tensor spectrum
Daniel Carney, Willy Fischler, Ely D. Kovetz +2
We consider the effects of fields with suddenly changing mass on the inflationary power spectra. In this context, when a field becomes light, it will be excited. This process contr…
