Problemas de las Teorías Cuánticas de Campos en Espacios-Tiempos Curvos
Quantum Field Theory is the fundamental theoretical framework of the Stan-<br />dard Model of elementary particles. This theory is formulated in a Minkowski<br />space-time. However, the actual space-time metric is never of that type. On<br />Earth, even at short distances, the metric is affected by both the force of the<br />Earth’s gravity and the solar force, but especially by the acceleration of the<br />Earth’s motion. At large distances the cosmological data lead one to think<br />that, on average, the metric is of the Friedmann-Lemaitre-Roberson-Walker<br />type.<br />The analysis of the quantization of fields in the presence of gravitational fields<br />involves a number of theoretical issues that we intend to explore in this work;<br />meaning how QFT can be adapted to introduce a gravitational background.<br />The key aspects treated throughout this work include the mathematical back-<br />ground that will be used; scalar fields in expanding universes; thermal aspects<br />of non inertial observers; and the renormalization problems regarding gravi-<br />tational dynamics.<br /><br />
