Leading order corrections to the cosmological evolution of tensor perturbations in braneworld (Short version)
Tsutomu Kobayashi, Takahiro Tanaka
Tensor perturbations in an expanding braneworld of the Randall Sundrum type are investigated. We consider a model composed of a slow-roll inflation phase and the succeeding radiati…
AdS/CFT correspondence in a Friedmann-Lemaitre-Robertson-Walker brane
Takahiro Tanaka
According to the AdS/CFT correspondence conjecture, the Randall-Sundrum infinite braneworld is equivalent to four dimensional Einstein gravity with super Yang-Mills fi…
Application of the Separate Universe Approach to Preheating
Takahiro Tanaka, Bruce Bassett
The dynamics of preheating after inflation has not been clearly understood yet.In particular, the issue of the generation of metric perturbations during preheating on super-horizon…
Can a brane fluctuate freely?
Akihiro Ishibashi, Takahiro Tanaka
No, it cannot in the following sense if a self-gravitating vacuum brane is concerned. Once we write down the full set of linear perturbation equations of the system containing a se…
A comment on trans-Planckian physics in inflationary universe
Takahiro Tanaka
There are several works searching for a clue of trans-Planckian physics on the primordial density perturbation spectrum. Here we would like to point out an important aspect which h…
Gravitational Radiation Reaction to a Particle Motion II: Spinning Particle
Yasushi Mino, Misao Sasaki, Takahiro Tanaka
We discuss the leading order correction to the equation of motion of a particle with spin on an arbitrary spacetime. A particle traveling in a curved spacetime is known to trace a…
