Modelling a Particle Detector in Field Theory
Fabio Costa, Federico Piazza
Particle detector models allow to give an operational definition to the particle content of a given quantum state of a field theory. The commonly adopted Unruh-DeWitt type of detec…

Renormalized Thermal Entropy in Field Theory
Sergio Cacciatori, Fabio Costa, Federico Piazza
Standard entropy calculations in quantum field theory, when applied to a subsystem of definite volume, exhibit area-dependent UV divergences that make a thermodynamic interpretatio…
