Semiclassical regime of Regge calculus and spin foams
Eugenio Bianchi, Alejandro Satz
Recent attempts to recover the graviton propagator from spin foam models involve the use of a boundary quantum state peaked on a classical geometry. The question arises whether bey…
A new expression for the transition rate of an accelerated particle detector
J. Louko, A. Satz
We analyse the instantaneous transition rate of an accelerated Unruh-DeWitt particle detector whose coupling to a quantum field on Minkowski space is regularised by a finite spatia…
Then again, how often does the Unruh-DeWitt detector click if we switch it carefully?
Alejandro Satz
The transition probability in first-order perturbation theory for an Unruh-DeWitt detector coupled to a massless scalar field in Minkowski space is calculated. It has been shown re…
Excited by a quantum field: Does shape matter?
Jorma Louko, Alejandro Satz
The instantaneous transition rate of an arbitrarily accelerated Unruh-DeWitt particle detector on four-dimensional Minkowski space is ill defined without regularisation. We show th…
