Hawking Radiation from Universal Horizons
Mario Herrero-Valea, Stefano Liberati, Raquel Santos-Garcia
The persistence of a suitable notion of black hole thermodynamics in Lorentz breaking theories of gravity is not only a non-trivial consistency test for such theories, it is also a…
Weighing the Vacuum Energy
Enrique Alvarez, Jesus Anero, Raquel Santos-Garcia
We discuss the weight of vacuum energy in various contexts. First, we compute the vacuum energy for flat spacetimes of the form , where $\mathbb{T}^…
Non-minimal Tinges of Unimodular Gravity
Mario Herrero-Valea, Raquel Santos-Garcia
Unimodular Gravity is normally assumed to be equivalent to General Relativity for all matters but the character of the Cosmological Constant. Here we discuss this equivalence in th…
A note on unimodular AdS supergravity
Jesus Anero, Carmelo P. Martin, Raquel Santos-Garcia
We put forward a unimodular anti-de Sitter supergravity theory off shell. This theory, where the Cosmological Constant does not couple to gravity, has a unique maximally…
CFT in Conformally Flat Spacetimes
Enrique Alvarez, Raquel Santos-Garcia
A new class of conformal field theories is presented, where the background gravitational field is conformally flat. Conformally flat (CF) spacetimes enjoy conformal properties quit…
Off-shell unimodular N=1, d=4 supergravity
Jesus Anero, Carmelo P. Martin, Raquel Santos-Garcia
We formulate a unimodular N=1, d=4 supergravity theory off shell. We see that the infinitesimal Grassmann parameters defining the unimodular supergravity transformations are constr…
