Brane Induced Gravity: Codimension-2
Nemanja Kaloper
We review the results of arXiv:hep-th/0703190, on brane induced gravity (BIG) in 6D. Among a large diversity of regulated codimension-2 branes, we find that for near-critical tensi…
Geometric Precipices in String Cosmology
Nemanja Kaloper, Scott Watson
We consider the effects of graviton multiplet fields on transitions between string gas phases. Focusing on the dilaton field, we show that it may obstruct transitions between diffe…
How (Not) to Palatini
Alberto Iglesias, Nemanja Kaloper, Antonio Padilla +1
We revisit the problem of defining non-minimal gravity in the first order formalism. Specializing to scalar-tensor theories, which may be disguised as `higher-derivative' models wi…
A New Dimension Hidden in the Shadow of a Wall
Nemanja Kaloper
We propose a new way to hide the fifth dimension, and to modify gravity in the far infra-red. A gravitating tensional membrane in five dimensions folds the transverse space into a…
