Sequestered Inflation
Renata Kallosh, Andrei Linde, Timm Wrase +1
We construct supergravity models allowing to sequester the phenomenology of inflation from the Planckian energy scale physics. The procedure consists of two steps: At Step I we stu…
IIB String Theory and Sequestered Inflation
Renata Kallosh, Andrei Linde, Timm Wrase +1
We develop sequestered inflation models, where inflation occurs along flat directions in supergravity models derived from type IIB string theory. It is compactified on a ${\mathbb{…
Aether SUSY breaking: Can aether be alternative to F-term SUSY breaking?
Yusuke Yamada
We investigate supersymmetry (SUSY) breaking scenarios where both SUSY and Lorentz symmetry are broken spontaneously. For concreteness, we propose models in which scalar fluid or v…
Superadiabatic basis in cosmological particle production: application to preheating
Yusuke Yamada
We discuss the adiabatic basis dependence of particle number in time-dependent backgrounds. In particular, we focus on preheating after inflation, and show that, for the optimal ba…
Chiral gravitational effect in time-dependent backgrounds
Kohei Kamada, Jun'ya Kume, Yusuke Yamada
Gravitational counterpart of the chiral magnetic effect, which is referred as the chiral gravitational effect, can also be of interest in a cosmological setup. In this study, we in…
Stokes phenomenon and gravitational particle production -- How to evaluate it in practice
Soichiro Hashiba, Yusuke Yamada
We revisit gravitational particle production from the Stokes phenomenon viewpoint, which helps us make a systematic way to understand asymptotic behavior of mode functions in time-…
