Primordial Non-Gaussianity from G-inflation
Fengge Zhang, Yungui Gong, Jiong Lin +2
Enormous information about interactions is contained in the non-Gaussianities of the primordial curvature perturbations, which are essential to break the degeneracy of inflationary…
Primordial black holes and secondary gravitational waves from natural inflation
Qing Gao, Yungui Gong, Zhu Yi
The production of primordial black hole (PBH) dark matter (DM) and the generation of scalar induced secondary gravitational waves by using the enhancement mechanism with a peak fun…
Primordial black holes and secondary gravitational waves from inflationary model with a non-canonical kinetic term
Zhu Yi, Qing Gao, Yungui Gong +1
With the enhancement mechanism provided by a noncanonical kinetic term with a peak, the amplitude of primordial curvature perturbations can be enhanced by seven orders of magnitude…
Primordial black holes and secondary gravitational waves from the Higgs field
Zhu Yi, Yungui Gong, Bin Wang +1
We devise a novel mechanism and for the first time demonstrate that the Higgs model in particle physics can drive the inflation to satisfy the cosmic microwave background observati…
