Tunnelling methods and Unruh-DeWitt detectors in curved spacetimes
Giovanni Acquaviva
In this contribution we describe some interesting interplay between quantum theory, general relativity and thermodynamics. In order to highlight the connection between these theori…
Ray tracing in FLRW flat space-times
Giovanni Acquaviva, Luca Bonetti, Guido Cognola +1
In this work we take moves from the debate triggered by Melia et al [9]. and followed by opposite comments by Lewis and Oirschot [10,11]. The point in question regards the role of…
Quantum fields in gravity
Giovanni Acquaviva
We give a brief description of some compelling connections between general relativity and thermodynamics through i) the semi-classical tunnelling method(s) and ii) the field-theore…
Thermal aspects in curved metrics
Giovanni Acquaviva
In this paper we describe two approaches that allow to calculate some thermal features as perceived by different observers in curved spacetimes: the tunnelling method and the Unruh…
