Séminaire du LPTMS : Giovanni Acquaviva

Semi-classical and quantum effects in curved metrics

Giovanni Acquaviva, University of Trento

Since the work by Hartle and Hawking, black hole spacetimes constituted an excellent playground for the study of quantum effects in curved metrics: in this context a great deal of theoretical tools have been employed in order to unveil the connections between general relativity and the quantum realm.  In the seminar I will present two approaches that allow to highlight this aspect: i) the semi-classical tunneling method and ii) the quantum field-theoretical modeling of Unruh-DeWitt detectors.  One of the open questions in this field regards the everpresent role of thermodynamics: does it just constitutes a parallel arising from a fundamentally statistical treatment?  Or is there some more profound link?
