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…
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…
Transgressing the horizons: Time operator in two-dimensional dilaton gravity
Gabor Kunstatter, Jorma Louko
We present a Dirac quantization of generic single-horizon black holes in two-dimensional dilaton gravity. The classical theory is first partially reduced by a spatial gauge choice…
How often does the Unruh-DeWitt detector click? Regularisation by a spatial profile
Jorma Louko, Alejandro Satz
We analyse within first-order perturbation theory the instantaneous transition rate of an accelerated Unruh-DeWitt particle detector whose coupling to a massless scalar field on fo…
