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 /> 000133530 521__ $$aMáster Universitario en Física del Universo: Cosmología, Astrofísica, Partículas y Astropartículas 000133530 540__ $$aDerechos regulados por licencia Creative Commons 000133530 700__ $$aAsorey Carballeira, Manuel$$edir. 000133530 7102_ $$aUniversidad de Zaragoza$$bFísica Teórica$$cFísica Teórica 000133530 8560_ $$f728137@unizar.es 000133530 8564_ $$s567078$$uhttps://zaguan.unizar.es/record/133530/files/TAZ-TFM-2024-077.pdf$$yMemoria (eng) 000133530 909CO $$ooai:zaguan.unizar.es:133530$$pdriver$$ptrabajos-fin-master 000133530 950__ $$a 000133530 951__ $$adeposita:2024-04-24 000133530 980__ $$aTAZ$$bTFM$$cCIEN 000133530 999__ $$a20240130190120.CREATION_DATE
