Large scale power and running spectral index in New Old Inflation
Gia Dvali, Shamit Kachru
We have proposed a new class of inflationary scenarios in which the first stage of expansion is driven by "old" false vacuum inflation. This ends by nucleation of a bubble, which t…
High Temperature Symmetry Breaking, SUSY Flat Directions, and the Monopole Problem
Gia Dvali, Lawrence M. Krauss
Supersymmetric flat directions allow a generic counterexample to the phenomenon of symmetry restoration at high temperatures. We show that (exponentially) large VEVs can be develop…
Hybrid Inflation and Particle Physics
Gia Dvali, Lawrence M. Krauss, Hong Liu
The prototype hybrid SUSY SU(5) inflation models, while well motivated from particle physics, and while allowing an acceptable inflationary phase with little or no fine tuning, are…
REMOVING THE COSMOLOGICAL BOUND ON THE AXION SCALE
Gia Dvali
The current cosmological bound on the invisible axion scale may be avoided in the class of theories in which the gauge coupling constant is determined through the expectation value…
