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…
Squashed Giants: Bound States of Giant Gravitons
Sergey Prokushkin, Mohammad M. Sheikh-Jabbari
We consider giant gravitons in the maximally supersymmetric type IIB plane-wave, in the presence of a constant NSNS B-field background. We show that in response to the background B…
On Brane Inflation With Volume Stabilization
Jonathan P. Hsu, Renata Kallosh, Sergey Prokushkin
The distance between BPS branes in string theory corresponds to a flat direction in the effective potential. Small deviations from supersymmetry may lead to a small uplifting of th…
Properties Of Heterotic Vacua From Superpotentials
Katrin Becker, Melanie Becker, Keshav Dasgupta +1
We study the superpotential for the heterotic string compactified on non-Kahler complex manifolds. We show that many of the geometrical properties of these manifolds can be underst…
Geometric Model for Complex Non-Kaehler Manifolds with SU(3) Structure
Edward Goldstein, Sergey Prokushkin
For a given complex n-fold M we present an explicit construction of all complex (n+1)-folds which are principal holomorphic T2-fibrations over M. For physical applications we consi…
Supergravity, Dark Energy and the Fate of the Universe
Renata Kallosh, Andrei Linde, Sergey Prokushkin +1
We propose a description of dark energy and acceleration of the universe in extended supergravities with de Sitter (dS) solutions. Some of them are related to M-theory with non-com…
