Ghost-free modification of the Polyakov action and Hawking radiation
Jens Boos, Valeri P. Frolov, Andrei Zelnikov
In this paper we discuss possible effects of non-locality in black hole spacetimes. We consider a two-dimensional theory in which the action describing matter is a ghost-free modif…
Self-force on a static particle near a black hole
Pavel Krtouš, Andrei Zelnikov
We study the self-force acting on a static charged point-like particle near a Schwarzschild black hole. We obtain the point-like particle as a limit of a spacetime describing a big…
Thermodynamics of two black holes
Pavel Krtouš, Andrei Zelnikov
We study a system of two charged non-rotating black holes separated by a strut. Using the exact solution of the Einstein-Maxwell equations, which describes this system, we construc…
On thermal field fluctuations in ghost-free theories
Jens Boos, Valeri P. Frolov, Andrei Zelnikov
We study the response of a scalar thermal field to a -probe in the context of non-local ghost-free theories. In these theories a non-local form factor is inserted into the kinet…
Probing the vacuum fluctuations in scalar ghost-free theories
Jens Boos, Valeri P. Frolov, Andrei Zelnikov
We discuss the response of vacuum fluctuations to a static potential in the context of massive, ghost-free infinite-derivative scalar field theories in two dimensions. For the spec…
