Dynamical analysis of modified gravity with nonminimal gravitational coupling to matter
Rui An, Xiaodong Xu, Bin Wang +1
We perform a phase space analysis of a generalized modified gravity theory with nonminimally coupling between geometry and matter. We apply the dynamical system approach to this ge…
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…
The reconstruction of inflationary potentials
Jianmang Lin, Qing Gao, Yungui Gong
The observational data on the anisotropy of the cosmic microwave background constraints the scalar spectral tilt and the tensor to scalar ratio which depend on the first…
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…
Thermodynamics of scalar-tensor theory with non-minimally derivative coupling
Yumei Huang, Yungui Gong, Dicong Liang +1
With the usual definitions for the entropy and the temperature associated with the apparent horizon, we show that the unified first law on the apparent horizon is equivalent to the…
