Abstract
On the one hand, quantum field theory in curved spacetimes (QFTCS) is the best formalism we have for studying quantum effects in predefined spacetimes at energies low enough such that quantum gravitational degrees of freedom -- whatever they are -- are not excited. On the other hand, QFTCS is not reliable, in general, to explain how quantum systems impact our present space-time concept: a smooth manifold equipped with a metric. In this project, we propose to continue analyzing aspects of QFTCS, where we have given our main contributions and to add a new front looking for insights at low energies on how matter and space-time could evolve harmoniously according to quantum mechanics. Recent solid developments suggest that quantum gravity insights may indeed derive from this type of analysis. (AU)
