Dynamics of nonminimally coupled scalar field models with generic potentials in FLRW background

چکیده

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

Energy density of nonminimally coupled scalar field cosmologies.

Scalar elds coupled to gravity via R 2 in arbitrary Friedmann-RobertsonWalker backgrounds can be represented by an e ective at space eld theory. We derive an expression for the scalar energy density where the e ective scalar mass becomes an explicit function of and the scale factor. The scalar quartic self-coupling gets shifted and can vanish for a particular choice of . Gravitationally induced...

Fresh inflation with nonminimally coupled inflaton field

I study a fresh inflationary model with a scalar field nonminimally coupled to gravity. An example is examined. I find that, as larger is the value of p (a ∼ tp), smaller (but larger in its absolute value) is the necessary value of the coupling ξ to the inflaton field fluctuations can satisfy a scale invariant power spectrum.

No hair for spherical black holes: Charged and nonminimally coupled scalar field with self-interaction.

Avraham E. Mayo and Jacob D. Bekenstein The Racah Institute of Physics, Hebrew University of Jerusalem, Givat Ram, Jerusalem 91904, Israel (March 1, 1996) We prove three theorems in general relativity which rule out scalar hair of static, spherically symmetric, possibly electrically charged black holes. We rst generalize Bekenstein's no{hair theorem for a multiplet of minimally coupled real sca...

Bouncing Universe with a Nonminimally Coupled Scalar Field on a Moving Domain Wall

We study dynamics of a dark energy component nonminimally coupled to gravity on a moving domain wall. We use this setup to explain late-time accelerated expansion and crossing of the phantom divide line by the equation of state parameter of this non-minimally coupled dark energy component. By analyzing parameter space of the model, we show that this model accounts for accelerated expansion and ...
