Systematics of multi-field effects at the end of warped brane inflation
Heng-Yu Chen, Jinn-Ouk Gong, Gary Shiu
We investigate in the context of brane inflation the possibility of additional light scalar fields generating significant power spectrum and non-Gaussianities at the end of inflati…
Multifield DBI Inflation and Non-Gaussianities
Min-xin Huang, Gary Shiu, Bret Underwood
We analyze the trajectories for multifield DBI inflation, which can arise in brane inflation models, and show that the trajectories are the same as in typical slow roll inflation.…
D3-brane Vacua in Stabilized Compactifications
Oliver DeWolfe, Liam McAllister, Gary Shiu +1
D3-branes feel no force in no-scale flux compactifications of type IIB string theory, but the nonperturbative effects required to stabilize the Kahler moduli break the no-scale str…
