Revisiting the cuscuton as a Lorentz-violating gravity theory
Jishnu Bhattacharyya, Andrew Coates, Mattia Colombo +2
The cuscuton is a scalar field with infinite speed of propagation. It was introduced in the context of cosmology but it has also been claimed to resemble Horava gravity in a certai…
Asymptotically Lifshitz spacetimes with universal horizons in dimensions
Sayandeb Basu, Jishnu Bhattacharyya, David Mattingly +1
Horava gravity theory possesses global Lifshitz space as a solution and has been conjectured to provide a natural framework for Lifshitz holography. We derive the conditions on the…
Universal horizons in maximally symmetric spaces
Jishnu Bhattacharyya, David Mattingly
Universal horizons in Hořava-Lifshitz gravity and Einstein-æther theory are the equivalent of causal horizons in general relativity and appear to have many of the same properties,…
Towards thermodynamics of universal horizons in Einstein-æther theory
Per Berglund, Jishnu Bhattacharyya, David Mattingly
Holography grew out of black hole thermodynamics, which relies on the causal structure and general covariance of general relativity. In Einstein-æther theory, a generally covariant…
Mechanics of universal horizons
Per Berglund, Jishnu Bhattacharyya, David Mattingly
Modified gravity models such as Hořava-Lifshitz gravity or Einstein-æther theory violate local Lorentz invariance and therefore destroy the notion of a universal light cone. Despit…
Charged Dilatonic AdS Black Branes in Arbitrary Dimensions
Per Berglund, Jishnu Bhattacharyya, David Mattingly
We study electromagnetically charged dilatonic black brane solutions in arbitrary dimensions with flat transverse spaces, that are asymptotically AdS. This class of solutions inclu…
