Bottom up approach to quantum gravity
Enrique Alvarez
A general introduction is given to what can be predicated about quantum gravity once the lessons from the standard model of particle physics are taken into account. In particular,…
The Imaginary Part of the Cosmological Constant
Enrique Álvarez, Roberto Vidal
Contents included in arXiv:1004.4867
Comments on the vacuum energy decay
Enrique Álvarez, Roberto Vidal
The {\em instability of vacuum energy} in de Sitter space as discussed recently by Polyakov is argued to be a generic feature when external gravitational fields are present. It is…
Weyl transverse gravity (WTDiff) and the cosmological constant
Enrique Álvarez, Roberto Vidal
Scale invariant (transverse) gravitational theories are introduced. They are invariant under pure metric rescalings (i.e. the matter fields are inert under those). This symmetry fo…
