Casimir interaction of finite-width strings
Yuri V. Grats, Pavel Spirin
Within the trln-formalism we investigate the vacuum interaction of cosmic strings and the influence of strings width on this effect. For the massless real scalar field we compute t…
Vacuum polarization and classical self-action near higher-dimensional defects
Yuri V. Grats, Pavel Spirin
We analyze the gravity-induced effects associated with a massless scalar field in a higher-dimensional spacetime being the tensor product of -dimensional Minkowski space and…
Lorentz-covariant perturbation theory for relativistic gravitational bremsstrahlung
Dmitri V. Gal'tsov, Yuri V. Grats, Alexander A. Matiukhin
We formulate Lorentz-covariant classical perturbation theory to deal with relativistic bremsstrahlung under gravitational scattering. Our approach is a version of the fast motion a…
Vacuum polarization near cosmic string in RS2 brane world
Yuri Grats, Anton Rossikhin
Gravitational field of cosmic strings in theories with extra spatial dimensions must differ significantly from that in the Einstein's theory. This means that all gravity induced pr…
Self-forces in the Spacetime of Multiple Cosmic Strings
E. R. Bezerra de Mello, V. B. Bezerra, Yu. V. Grats
We calculate the electromagnetic self-force on a stationary linear distribution of four-current in the spacetime of multiple cosmic strings. It is shown that if the current is infi…
