New exact solutions for inflationary cosmological perturbations
From a general ansatz for the effective potential of cosmological perturbations we find new, exact solutions in single-scalar-field inflation: A three parameter family of exact solutions that encompasses all exact solutions that have been known previously (power-law inflation, Easther’s model, and a generalized version of Starobinsky’s solution). The main feature of this new family is that the ...
متن کاملExact Inflationary Solutions from a Superpotential
We propose a novel, potentially useful generating technique for constructing exact solutions of inflationary scalar field cosmologies with non-trivial potentials. The generating scheme uses the so-called superpotential and is inspired by recent studies of similar equations in supergravity. Some exact solutions are derived, and the physical meaning of the superpotential in these models is clarif...
متن کاملAnother Exact Inflationary Solution
A new closed-form inflationary solution is given for a hyperbolic interaction potential. The method used to arrive at this solution is outlined as it appears possible to generate additional sets of equations which satisfy the model. In addition a new form of decaying cosmological constant is presented. PACS numbers: 98.80.Hw, 98.80.Bp, 04.60.+n
متن کاملThe exact numerical treatment of inflationary models
The precision reached by the recent CMB measurements gives new insights into the shape of the primordial power spectra of the cosmological perturbations. In the context of inflationary cosmology, this implies that the CMB data are now sensitive to the form of the inflaton potential. Most of the current approaches devoted to the derivation of the inflationary primordial power spectra, or to the ...
متن کاملInflationary Solutions in Quantum Cosmology
We prove that in the Hartle-Hawking approach to quantum cosmology the existence of an inflationary phase is a general property of minisuperspace models given by a closed Friedmann-Robertson-Walker universe containing a massless scalar field with a λφ self-interaction. The evolution in time of the cosmic scale factor and of the scalar field in the very early universe is derived, together with th...
