Extended inflation with a curvature-coupled inflaton.
We examine extended inflation models enhanced by the addition of a coupling between the inflaton field and the space-time curvature. We examine two types of model, where the underlying inflaton potential takes on second-order and first-order form respectively. One aim is to provide models which satisfy the solar system constraints on the Brans– Dicke parameter ω. This constraint has proven very...
متن کاملFresh 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.

© Springer-Verlag Berlin Heidelberg 2015 Y.S. Zhao (ed.), Organic Nanophotonics, Nano-Optics and Nanophotonics, DOI 10.1007/978-3-662-45082-6_2 Abstract The photophysics of planar microcavities which employ organic materials as the optically resonant medium to achieve the strong-coupling regime is discussed. While as a result of the light–matter coupling, cavity polariton branches appear which ...
متن کاملStrongly Coupled Gravity and Duality
A strong coupling limit of theories whose low-energy effective field theory is 5-dimensional N = 8 supergravity is proposed in which the gravitational coupling becomes large. It is argued that, if this limit exists, it should be a 6-dimensional theory with (4,0) supersymmetry compactified on a circle whose radius gives the 5-dimensional Planck length. The sector corresponding to the D = 5 super...
متن کاملStrongly coupled quantum field theory
We analyze numerically a two-dimensional λφ theory showing that in the limit of a strong coupling λ → ∞ just the homogeneous solutions for time evolution are relevant in agreement with the duality principle in perturbation theory as presented in [M.Frasca, Phys. Rev. A 58, 3439 (1998)], being negligible the contribution of the spatial varying parts of the dynamical equations. A consequence is t...
