Roulette Inflation with Kähler Moduli and their Axions
J. R. Bond, L. Kofman, S. Prokushkin +1
We study 2-field inflation models based on the ``large-volume'' flux compactification of type IIB string theory. The role of the inflaton is played by a Kähler modulus τcorrespondi…
On the new string theory inspired mechanism of generation of cosmological perturbations
Nemanja Kaloper, Lev Kofman, Andrei Linde +1
Recently a non-inflationary mechanism of generation of scale-free cosmological perturbations of metric was proposed by Brandenberger, Nayeri, and Vafa in the context of the string…
Nonlinear Inflaton Fragmentation after Preheating
Gary N. Felder, Lev Kofman
We consider the nonlinear dynamics of inflaton fragmentation during and after preheating in the simplest model of chaotic inflation. While the earlier regime of parametric resonant…
Preheating with Trilinear Interactions: Tachyonic Resonance
J. F. Dufaux, G. N. Felder, L. Kofman +2
We investigate the effects of bosonic trilinear interactions in preheating after chaotic inflation. A trilinear interaction term allows for the complete decay of the massive inflat…
