Eternal inflation near inflection points: a challenge to primordial black hole models
Eemeli Tomberg, Konstantinos Dimopoulos
Inflation with an inflection point potential is a popular model for producing primordial black holes. The potential near the inflection point is approximately flat, with a local ma…
Quintessential Inflation in Palatini gravity
Konstantinos Dimopoulos, Christian Dioguardi, Gert Hütsi +1
Palatini gravity, with the inflaton kinetic term, proved to be a powerful framework for generating asymptotically flat inflaton potentials. Here we show that a quadrat…
Flipped Rotating Axion Non-minimally Coupled to Gravity: Baryogenesis and Dark Matter
Chao Chen, Suruj Jyoti Das, Konstantinos Dimopoulos +1
We demonstrate that the co-genesis of baryon asymmetry and dark matter can be achieved through the rotation of an axion-like particle, driven by a flip in the vacuum manifold's dir…
