Recent advances in extended inflationary cosmology
Paul J. Steinhardt
Extended inflation is a promising new approach to implementing the inflationary universe scenario. This paper reviews recent advances including a new, more robust mechanism for end…
Gravity's rainbow
George F. Smoot, Paul J. Steinhardt
Could COBE DMR be detecting the imprint from a spectrum of gravitational waves generated during inflation? The conventional inflationary prediction had been that the cosmic microwa…
Challenges for Superstring Cosmology
Ram Brustein, Paul Steinhardt
We consider whether current notions about superstring theory below the Planck scale are compatible with cosmology. We find that the anticipated form for the dilaton interaction cre…
Graceful Exit in Extended Inflation and Implications for Density Perturbations
R. Crittenden, Paul J. Steinhardt
Two qualitatively different modes of ending superluminal expansion are possible in extended inflation. One mode, different from the one envoked in most extended models to date, eas…
Cosmic Microwave Background Probes Models of Inflation
R. L. Davis, H. M. Hodges, G. F. Smoot +2
Inflation creates both scalar (density) and tensor (gravity wave) metric perturbations. We find that the tensor mode contribution to the CMB anisotropy on large-angular scales can…
