We study the phase space analysis of a nonminimally coupled scalar field model with generic potentials such as KKLT, Higgs, inverse and inverse square. Our investigation brings new asymptotic regimes, and obtains stable de-Sitter solution. In case of KKLT, we do not find stable de-Sitter solution whereas Higgs model satisfies the de-Sitter condition but does not provide a stable de-Sitter solution in usual sense as one of the eigenvalue is zero. We obtain time derivative of Hubble constant \({\dot{H}}=0\), equation of state \(w_{\phi }\simeq -1\), scalar field \(\phi =\) constant and the positive effective gravitational constant (\(G_{eff}>0\)), which are missed in our earlier work. Therefore, in case of \(F(\phi )R\) coupling with \(F(\phi )= 1-\xi \phi ^2 \) and the models of inverse and inverse square potentials− a true stable de-Sitter solution is trivially satisfied.

我们研究了具有非凡耦合标量场模型的相空间分析，该模型具有通用电势，例如KKLT，Higgs，反方和反方。我们的研究带来了新的渐近机制，并获得了稳定的de-Sitter解。对于KKLT，我们找不到稳定的de-Sitter解，而希格斯模型满足de-Sitter条件，但由于特征值之一为零，因此在通常意义上没有提供稳定的de-Sitter解。我们获得哈勃常数\（{\ dot {H}} = 0 \）的时间导数，状态方程\（w _ {\ phi} \ simeq -1 \），标量场\（\ phi = \）常数和正有效引力常数（\（G_ {eff}> 0 \）），这在我们之前的工作中没有提及。因此，在\（F（\ phi）R \）的情况下结合\（F（\ phi）= 1- \ xi \ phi ^ 2 \）以及平方和平方反比的模型-真正满足稳定的De-Sitter解的要求。
