Abstract
The search for the fundamental theory which describes Nature at the Planck scale still seems to be far from being accomplished. Notwithstanding, whatever this theory turns out to be, it should contain Quantum Field Theory in the low-energy limit. In the case that matter fields are under the influence of strong gravitational fields, the standard formalism should be extended to take into account the existence of more general spacetimes. As a consequence, it was developed on the bases of General Relativity and Quantum Field Theory the Semi classical Gravity Theory (SGT) or Quantum Field Theory in Curved Spacetime (QFTCS). The SGT not only has led to more precise calculations for processes involving elementary particles in the presence of strong gravitational fields, but also has accomplished some surprising predictions as, e.g., the Hawking and the Unruh effects. The first one illustrates that QFTCS can anticipate macroscopic quantum gravity effects while the second one illustrates its power to clarify subtle conceptual issues. The present project has a multidisciplinary flavor. Recent developments have brought QFTCS over Information Theory (due to the information paradox associated with black hole evaporation) and Condensed Matter. The direct observation of QFTCS effects is not an easy task. Happily, this should be circumvented by the introduction of the gravitational analogs in condensed matter, which will receive particular attention. Finally, we shall explore the consequences of our investigations in classical physics, as e.g. in Thermodynamics of Black Holes. (AU)
