Micro Black Holes and the Democratic Transition
Gia Dvali, Oriol Pujolas
Unitarity implies that the evaporation of microscopic quasi-classical black holes cannot be universal in different particle species. This creates a puzzle, since it conflicts with…
Quantum Information and Gravity Cutoff in Theories with Species
Gia Dvali, Cesar Gomez
We show that lowering of the gravitational cutoff relative to the Planck mass, imposed by black hole physics in theories with N species, has an independent justification from quant…
A Model Independent Ultraviolet Cutoff for Theories with Charged Massive Higher Spin Fields
Massimo Porrati, Rakibur Rahman
We argue that the theory of a massive higher spin field coupled to electromagnetism in flat space possesses an intrinsic, model independent, finite upper bound on its UV cutoff. By…
Watching Worlds Collide: Effects on the CMB from Cosmological Bubble Collisions
Spencer Chang, Matthew Kleban, Thomas S. Levi
We extend our previous work on the cosmology of Coleman-de Luccia bubble collisions. Within a set of approximations we calculate the effects on the cosmic microwave background (CMB…
General Massive Spin-2 on de Sitter Background
Gregory Gabadadze, Alberto Iglesias, Yanwen Shang
We study linearized massive gravity on the de Sitter background. With a small-enough graviton mass this may have had relevance to inflation, or the present-day cosmic acceleration.…
Topologically Massive Gravity at the Chiral Point is Not Unitary
Gaston Giribet, Matthew Kleban, Massimo Porrati
A recent paper [arXiv:0801.4566] claims that topologically massive gravity contains only chiral boundary excitations at a particular value of the Chern-Simons coupling. On the othe…
