Asymptotically nonlocal gravity
Jens Boos, Christopher D. Carone
Asymptotically nonlocal field theories interpolate between Lee-Wick theories with multiple propagator poles, and ghost-free nonlocal theories. Previous work on asymptotically nonlo…
Asymptotic nonlocality in gauge theories
Jens Boos, Christopher D. Carone
Asymptotically nonlocal field theories represent a sequence of higher-derivative theories whose limit point is a ghost-free, infinite-derivative theory. Here we extend this framewo…
Asymptotic nonlocality
Jens Boos, Christopher D. Carone
We construct a theory of real scalar fields that interpolates between two different theories: a Lee-Wick theory with propagator poles, including Lee-Wick partners, and a…
Retarded field of a uniformly accelerated source in non-local scalar field theory
Ivan Kolář, Jens Boos
We study the retarded field sourced by a uniformly accelerated particle in a non-local scalar field theory. While the presence of non-locality regularizes the field at the location…
Ultrarelativistic charged and magnetized objects in non-local ghost-free electrodynamics
Jens Boos, Valeri P. Frolov, Jose Pinedo Soto
We study a non-local ghost-free Lorentz invariant modification of the Maxwell equations in four- and higher-dimensional flat spacetimes. We construct solutions of these equations f…
Resonant particle creation by a time-dependent potential in a nonlocal theory
Jens Boos, Valeri P. Frolov, Andrei Zelnikov
Considering an exactly solvable local quantum theory of a scalar field interacting with a -shaped time-dependent potential we calculate the Bogoliubov coefficients analytically…
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…
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…
Quantum scattering on a delta potential in ghost-free theory
Jens Boos, Valeri P. Frolov, Andrei Zelnikov
We discuss the quantum-mechanical scattering of a massless scalar field on a -potential in a ghost-free theory and obtain analytic solutions for the scattering coefficients. Due…
