Natura Non Facit Saltum: An Analytical Model of Smooth Slow-Roll to Ultra-Slow-Roll Transition
Diego Cruces, Minxi He, Shi Pi +3
In this letter, we propose a single-field inflation model that realizes a slow-roll-to-ultra-slow-roll transition while keeping the second slow-roll parameter smoothly varying thro…
Increase of in regularized pole inflation & Einstein-Cartan gravity
Minxi He, Muzi Hong, Kyohei Mukaida
We show that the regularization of the second order pole in the pole inflation can induce the increase of , which may be important after the latest data release of cosmic micr…
Formation threshold of rotating primordial black holes
Minxi He, Teruaki Suyama
Within the framework that primordial black holes are formed by the direct gravitational collapse of large primordial density perturbations in the radiation dominated stage, we deri…
Differentiating G-inflation from String Gas Cosmology using the Effective Field Theory Approach
Minxi He, Junyu Liu, Shiyun Lu +4
A characteristic signature of String Gas Cosmology is primordial power spectra for scalar and tensor modes which are almost scale-invariant but with a red tilt for scalar modes but…
