The Reconstruction of Non-Minimal Derivative Coupling Inflationary Potentials
Qin Fei, Zhu Yi, Yingjie Yang
We derive the reconstruction formulae for the inflation model with the non-minimal derivative coupling term. If reconstructing the potential from the tensor-to-scalar ratio, we cou…

The reconstruction of tachyon inflationary potentials
Qin Fei, Yungui Gong, Jiong Lin +1
We derive a lower bound on the field excursion for the tachyon inflation, which is determined by the amplitude of the scalar perturbation and the number of -folds before the end…

PPN parameters in gravitational theory with nonminimally derivative coupling
Zhu Yi, Yungui Gong
The nonminimal coupling of the kinetic term to Einstein's tensor helps the implementation of inflationary models due to the gravitationally enhanced friction. We calculate the para…
