Interaction of Hawking radiation with static sources in deSitter and Schwarzschild-deSitter spacetimes

J. Castineiras, I. P. Costa e Silva, G. E. A. Matsas

We study and look for similarities between the response rates $R^{dS} (a_{0}, Λ)$ and $R^{SdS} (a_{0}, Λ, M)$ of a static scalar source with constant proper acceleration $a_{0}$ in…

Do static sources respond to massive scalar particles from the Hawking radiation as uniformly accelerated ones do in the inertial vacuum?

J. Castineiras, I. P. Costa e Silva, G. E. A. Matsas

We revisit the recently found equivalence for the response of a static scalar source interacting with a {\em massless} Klein-Gordon field when the source is (i) static in Schwarzsc…
