Covariant techniques in Quantum Field Theory
Enrique Alvarez, Jesus Anero
In this paper some techniques useful to perform quantum field theory computations in a covariant manner are reviewed. In particular the background field gauge, the zeta function re…
Some comments on the Hamiltonian for Unimodular Gravity
Enrique Álvarez, Jesús Anero
Several alternative formulations of the first order approach to unimodular gravity are presented. There is always a particular one such that it is {\em classically} equivalent to t…
Effective action in elliptic and hyperbolic spacetimes
Enrique Alvarez, Jesus Anero
The full one-loop (scalar) effective action is computed for both hyperbolic and elliptic spacetimes.
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}^…
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…
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…
