Self-force on a scalar point charge in the long throat
Arkady A. Popov
An analytic method is presented which allows for the computation of the self-force for a static particle with a scalar charge in the region of an ultrastatic spacetime which one ca…
Renormalization for self-potential of a scalar charge in static space-times
Arkady A. Popov
A method is presented which allows for the renormalization of the self-potential for a scalar point charge at rest in static curved space-time. The method is suitable for the scala…
Rotating thin-shell wormhole from glued Kerr spacetimes
P. E. Kashargin, S. V. Sushkov
We construct a model of a rotating wormhole made by cutting and pasting two Kerr spacetimes. As a result, we obtain a rotating thin-shell wormhole with exotic matter at the throat.…
Dynamic model of spherical perturbations in the Friedman universe. III. Automodel solutions
Yu. G. Ignatyev, N. Elmakhi
A class of exact spherically symmetric perturbations of retarding automodel solutions linearized around Friedman background of Einstein equations for an ideal fluid with an arbitra…
Dynamic model of spherical perturbations in the Friedmann universe. II. retarding solutions for the ultrarelativistic equation of state
Yu. G. Ignatyev, N. Elmakhi
Exact linear retarding spherically symmetric solutions of Einstein equations linearized around Friedmann background for the ultrarelativistic equation of state are obtained and inv…
Self-force of a point charge in the space-time of a massive wormhole
Nail R. Khusnutdinov, Arkadii A. Popov, Lilia N. Lipatova
We consider the self-potential and the self-force for an electrically charged particle at rest in the massive wormhole space-time. We develop general approach for the renormalizati…
