Vacuum Polarization Effects of Pointlike Impurity
Yuri V. Grats, Pavel Spirin
We develop precise formulation for the effects of vacuum polarization near a pointlike source with a zero-range (-like) potential in three spatial dimensions. There are differen…
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…
Piercing of domain walls: new mechanism of gravitational radiation
Dmitri Gal'tsov, Elena Melkumova, Pavel Spirin
Domain wall (DW) moving in media undergoes the friction force due to particle scattering. However certain particles are not scattered, but perforate the wall. As a result, the wall…
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…
Domain Walls: Momentum Conservation in Absence of Asymptotic States
D. V. Gal'tsov, E. Yu. Melkumova, P. Spirin
Gravitational potentials of the domain walls in the linearized gravity are growing with distance, so the particle scattering by the wall can not be described in terms of free asymp…
Gravitational Bremsstrahlung from Massless-particle Collisions
Pavel Spirin, Theodore N. Tomaras
The angular and frequency characteristics of the gravitational radiation emitted in collisions of massless particles is studied perturbatively in the context of classical General R…
