On the possibility of blue tensor spectrum within single field inflation
Yi-Fu Cai, Jinn-Ouk Gong, Shi Pi +2
We present a series of theoretical constraints on the potentially viable inflation models that might yield a blue spectrum for primordial tensor perturbations. By performing a deta…

Inflation beyond T-models and primordial B-modes
Yi-Fu Cai, Jinn-Ouk Gong, Shi Pi
We describe extended theories which shares the gauge transformation symmetry of the T-models, and takes the T-models as well as Starobinsky model as special cases. We derive a gene…
