Constraints on the Primordial Curvature Power Spectrum by Pulsar Timing Array Data: A Polynomial Parameterization Approach
Qin Fei
The recent stochastic signal observed jointly by NANOGrav, PPTA, EPTA, and CPTA can be accounted for by scalar-induced gravitational waves (SIGWs). The source of the SIGWs is from…

Constant-roll tachyon inflation and observational constraints
Qing Gao, Yungui Gong, Qin Fei
For the constant-roll tachyon inflation, we derive the analytical expressions for the scalar and tensor power spectra, the scalar and tensor spectral tilts and the tensor to scalar…

Inflationary models with non-minimally derivative coupling
Nan Yang, Qin Fei, Qing Gao +1
We derive the general formulae for the the scalar and tensor spectral tilts to the second order for the inflationary models with non-minimally derivative coupling without taking th…
