The Inflationary Wavefunction and its Initial Conditions
Daniel Carney, Willy Fischler, Sonia Paban +1
We explore the effect of initial conditions on the inflationary wavefunction and their consequences for the observed spectrum of primordial fluctuations. In a class of models with…
Axion Inflation and Gravity Waves in String Theory
Renata Kallosh, Navin Sivanandam, Masoud Soroush
The majority of models of inflation in string theory predict an absence of measurable gravitational waves, r << 10^{-3}. The most promising proposals for making string theoretic mo…
Volume Weighted Measures of Eternal Inflation in the Bousso-Polchinski Landscape
Timothy Clifton, Stephen Shenker, Navin Sivanandam
We consider the cosmological dynamics associated with volume weighted measures of eternal inflation, in the Bousso-Polchinski model of the string theory landscape. We find that thi…
Islands in the landscape
T. Clifton, Andrei Linde, Navin Sivanandam
The string theory landscape consists of many metastable de Sitter vacua, populated by eternal inflation. Tunneling between these vacua gives rise to a dynamical system, which asymp…
Exact Attractive Non-BPS STU Black Holes
Renata Kallosh, Navin Sivanandam, Masoud Soroush
We develop some properties of the non-BPS attractive STU black hole. Our principle result is the construction of exact solutions for the moduli, the metric and the vectors in terms…
The Non-BPS Black Hole Attractor Equation
Renata Kallosh, Navin Sivanandam, Masoud Soroush
We study the attractor mechanism for extremal non-BPS black holes with an infinite throat near horizon geometry, developing, as we do so, a physical argument as to why such a mecha…
