Eternal inflation and localization on the landscape
D. Podolsky, K. Enqvist
We model the essential features of eternal inflation on the landscape of a dense discretuum of vacua by the potential , where is random. We fin…
Cosmological constraints on string scale and coupling arising from tachyonic instability
Kari Enqvist, Asko Jokinen, Anupam Mazumdar +2
We demonstrate that string motivated inflation ending via tachyonic instability leaves a detectable imprint on the cosmic microwave background (CMB) radiation by virtue of the exci…
A CMB/Dark Energy Cosmic Duality
Kari Enqvist, Martin S. Sloth
We investigate a possible connection between the suppression of the power at low multipoles in the CMB spectrum and the late time acceleration. We show that, assuming a cosmic IR/U…
Dumping inflaton energy density out of this world
Kari Enqvist, Anupam Mazumdar, A. Pérez-Lorenzana
We argue that a brane world with a warped, infinite extra dimension allows for the inflaton to decay into the bulk so that after inflation, the effective dark energy disappears fro…
