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 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…
Constraints on primordial curvature perturbations from primordial black hole dark matter and secondary gravitational waves
Yizhou Lu, Yungui Gong, Zhu Yi +1
Primordial black holes and secondary gravitational waves can be used to probe the small scale physics at very early time. For secondary gravitational waves produced after the horiz…
On the constant-roll inflation with large and small
Qing Gao, Yungui Gong, Zhu Yi
We study the seemingly duality between large and small for the constant-roll inflation with the second slow-roll parameter being a constant. In the previous studies, on…
Gauss-Bonnet inflation and swampland
Zhu Yi, Yungui Gong
The two swampland criteria are generically in tension with the single field slow-roll inflation because the first swampland criterion requires small tensor to scalar ratio while th…
