Double peaks of gravitational wave spectrum induced from inflection point inflation
Tie-Jun Gao, Xiu-Yi Yang
We investigate the possibility to induce double peaks of gravitational wave(GW) spectrum from primordial scalar perturbations in inflationary models with three inflection points.Wh…
Gauss-Bonnet inflation with a constant rate of roll
Tie-Jun Gao
We consider the constant-roll condition in the model of the inflaton nonminimal coupling to the Gauss-Bonnet term. By assuming the first Gauss-Bonnet flow parameter is a cons…
Low-frequency Gravitational Waves from Double-inflection-point Inflation
Wu-Tao Xu, Jing Liu, Tie-Jun Gao +1
We study the production of gravitational waves from primordial scalar perturbations in double-inflection-point inflation, in which one of the inflection points predicts the power s…
Primordial Black Hole Production in Inflationary Models of Supergravity with a Single Chiral Superfield
Tie-Jun Gao, Zong-Kuan Guo
We propose a double inflection point inflationary model in supergravity with a single chiral superfield. Such a model allows for the generation of primordial black holes(PBHs) at s…
Inflection point inflation and dark energy in supergravity
Tie-Jun Gao, Zong-Kuan Guo
We consider an inflection point inflationary model in supergravity with a single chiral superfield and show that the predicted values of the scalar spectral index and tensor-to-sca…
t-c gamma and t-cg in warped extra dimensions
Tie-Jun Gao, Tai-Fu Feng, Jian-Bin Chen
In this work, we calculate the top quark rare decays t-cgamma and t-cg in the framework where the standard model is embedded in a warped extra dimension with the custodial symmetry…
