Abstract

The influence of gravity on quantum phenomena and vice-versa can be analyzed using the formalism of Quantum Field Theory in Curved Spacetimes (QFTCS), in which matter and other interaction fields are quantized on a curved background spacetime. Using this formalism we recently unveiled the "vacuum awakening" mechanism, according to which well-behaved gravitational fields can trigger an exponential growth of the vacuum energy density of certain quantum fields. The purpose of this research project is to continue investigating the possible consequences of this mechanism in astrophysical and cosmological scenarios, as well as analyzing conceptual issues related to the backreaction of the vacuum energy on the background spacetime.
