Recursive relations from diffeomorphism in the Randall-Sundrum model
Haiying Cai, Giacomo Cacciapaglia
Models of gravity in warped extra dimensions enjoy invariance under diffeomorphism. We derive the nonlinear transformation rules for the metric perturbations in the unitary gauge.…

Exact Diffeomorphism in Warped Space
Haiying Cai
In this paper, we study the manifestation of exact diffeomorphism in warped extra dimension, with an emphasis on the Randall-Sundrum model. Utilizing the covariant form of variatio…

Diffeomorphism on-shell breaking from radion stabilization
Haiying Cai
We present for the first time the nonlinear diffeomorphism in the Randall Sundrum model that can keep the effective Lagrangian invariant in any order of expansion. We will show tha…
