We derive semi-analytic formulae for the local bispectrum and trispectrum in general two-field inflation and provide a simple geometric recipe for building observationally allowed models with observa...

We propose a warm inflationary model in the context of relativistic D-brane inflation in a warped throat. The inflaton has Dirac-Born-Infeld (DBI) kinetic term and is coupled to radiation through a di...

2010/12/23
A new hybrid inflationary scenario in the context of $f(R,{\Box}R)$-gravity is proposed. Demanding the waterfall field to 'support the potential from below' [unlike the original proposal by Stewart i...
On the one hand, inflation is an extremely convincing scenario: it solves most cosmological paradoxes and generates fluctuations that became the seeds for the growth of structures. It, however, suffer...

The discovery of many novel realizations of the inflationary universe paradigm has led to a degeneracy problem: many different inflationary Lagrangians generate the same perturbation spectra. Resolvi...

The Asymptotic Safety scenario predicts that the deep ultraviolet of Quantum Einstein Gravity is governed by a nontrivial renormalization group fixed point. Analyzing its implications for cosmology us...
Inflation of Bianchi type-$\Rmnum{7}_0$ Universe with Dirac Field in Einstein-Cartan theory

We discuss the Bianchi type-$\Rmnum{7}_0$ cosmology with Dirac field in Einstein-Cartan theory. We obtain the equations of Dirac field and gravitational field in Einstein-Cartan theory. We find a Bian...

We review the relevance of quantum rolling tachyons and corresponding inflation scenario in the frame of the standard, $p$-adic and adelic minisuperspace quantum cosmology. The field theory of tachyon...
Inflation in Entropic Cosmology: Primordial Perturbations and non-Gaussianities

We investigate thermal inflation in double-screen entropic cosmology. We find that its realization is general, resulting from the system evolution from non-equilibrium to equilibrium. Furthermore, goi...
Embedding (R+R^2)-Inflation into Supergravity
Inflation Supergravity High Energy Physics
<
2010/12/22
We find the natural embedding of the (R+R^2)-inflationary model into the recently constructed N=1 F(\cal R)-supergravity. It gives a simple and viable realization of chaotic inflation in supergravity....
Nonminimal Inflation on the Randall-Sundrum II Brane with Induced Gravity

2010/3/17
We study an inflation model that inflaton field is non-minimally coupled to the induced scalar curvature on the Randall-Sundrum (RS) II brane. We investigate the effects of the non-minimal coupling on...
