Correspondence between Loop-inspired and Braneworld Cosmology
Edmund J. Copeland, James E. Lidsey, Shuntaro Mizuno
Braneworld scenarios are motivated by string/M-theory and can be characterized by the way in which they modify the conventional Friedmann equations of Einstein gravity. An alternat…
Slow-roll corrections to inflaton fluctuations on a brane
Kazuya Koyama, Shuntaro Mizuno, David Wands
Quantum fluctuations of an inflaton field, slow-rolling during inflation are coupled to metric fluctuations. In conventional four dimensional cosmology one can calculate the effect…
BPS pp-wave brane cosmological solutions in string theory
Makoto Tanabe, Shuntaro Mizuno
We construct time dependent BPS pp-wave brane solutions in the context of M-theory and type II supergravity. It is found that N-brane solutions we considered satisfy the crossing r…
