Monodromy in the CMB: Gravity Waves and String Inflation
Eva Silverstein, Alexander Westphal
We present a simple mechanism for obtaining large-field inflation, and hence a gravitational wave signature, from string theory compactified on twisted tori. For Nil manifolds, we…
Accidental Inflation in String Theory
Andrei Linde, Alexander Westphal
We show that inflation in type IIB string theory driven by the volume modulus can be realized in the context of the racetrack-based Kallosh-Linde model (KL) of moduli stabilization…
Moduli Stabilization in Meta-Stable Heterotic Supergravity Vacua
Marco Serone, Alexander Westphal
We revisit the issue of moduli stabilization in a class of N=1 four dimensional supergravity theories which are low energy descriptions of standard perturbative heterotic string va…
Lifetime of Stringy de Sitter Vacua
Alexander Westphal
In this note we perform a synopsis of the life-times from vacuum decay of several de Sitter vacuum constructions in string/M-theory which have a single dS minimum arising from lift…
Consistent de Sitter String Vacua from Kahler Stabilization and D-term uplifting
Susha L. Parameswaran, Alexander Westphal
In this note, we review our construction of de Sitter vacua in type IIB flux compactifications, in which moduli stabilization and D-term uplifting can be combined consistently with…
de Sitter String Vacua from Perturbative Kahler Corrections and Consistent D-terms
Susha L. Parameswaran, Alexander Westphal
We present a new way to construct de Sitter vacua in type IIB flux compactifications, in which moduli stabilization and D-term uplifting can be combined in a manner consistent with…
