Bouncing cosmologies from Born-Infeld-type gravity
Yermek Aldabergenov, Wei Lin, Rongjian Li +2
We construct a Born-Infeld-type modification of gravity, where is the Gauss-Bonnet term, by embedding Born-Infeld electrodynamics in a five-dimensional p…

Towards Stochastic Inflation in Higher-Curvature Gravity
Yermek Aldabergenov, Ding Ding, Wei Lin +1
We study stochastic inflation in the presence of higher-curvature terms non-minimally coupled to the inflaton. Focusing on quadratic curvature invariants, we single out the Gauss-B…

Meso-inflationary Peccei-Quinn symmetry breaking with non-minimal coupling
Yermek Aldabergenov, Ding Ding, Wei Lin +1
We study a realization of the inflationary scenario where the Peccei-Quinn (PQ) symmetry is spontaneously broken during inflation, facilitated by its non-minimal coupling to gravit…
