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…
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…
Holographic Limitations of the Effective Field Theory of Inflation
Andreas Albrecht, Nemanja Kaloper, Yong-Seon Song
Holographic considerations may provide a glimpse of quantum gravity beyond what is currently accessible by other means. Here we apply holography to inflationary cosmology. We argue…
New Black Strings in Three Dimensions
Nemanja Kaloper
We present two different families of stationary black strings in three dimensions carrying electric and axion charges. Both solutions contain a singular region, which however is qu…
Three Dimensional Black Holes and Four Dimensional Black Strings as Nonlinear Sigma Models
Nemanja Kaloper
Two solutions of stringy gravity in three and four dimensions which admit interpretation as a black hole and a black string, respectively, are discussed. It is demonstrated that th…
