Influence of conformal symmetry on the amplitude ratios for O() models
H. A. S. Costa, P. R. S. Carvalho
In this Letter we compute analytically the effect of conformal symmetry on the radiative corrections to the amplitude ratios for O() massless scalar field theories in c…

Decoherence of a uniformly accelerated finite-time detector
Helder A. S. Costa
We study a uniformly accelerated detector coupled to a massless scalar field for a finite time interval. By considering the detector initially prepared in a superposition state, qu…

Ramsey interferometry as a witness of acceleration radiation
Helder A. S. Costa, Irismar G. da Paz, Paulo R. S. Carvalho +1
We adapt a typical Ramsey interferometer by inserting a linear accelerator capable of accelerating an atom inside a single-mode cavity. We demonstrate that this simple scheme allow…
