Synchrotron radiation in odd dimensions
D. V. Gal'tsov, M. Khlopunov
In odd space-time dimensions, the retarded solution of the massless wave equation has support not only on the light cone, but also inside it. At the same time, a free massless fiel…
Ghost-free Palatini derivative scalar-tensor theory: desingularization and the speed test
Dmitri Gal'tsov, Sophia Zhidkova
We disclose remarkable features of the scalar-tensor theory with the derivative coupling of the scalar field to the curvature in the Palatini formalism. Using the disformal transfo…
Higher- triangular dilatonic black holes
Anton Zadora, Dmitri V. Gal'tsov, Chiang-Mei Chen
Dilaton gravity with the form fields is known to possess dyon solutions with two horizons for the discrete ("triangular") values of the dilaton coupling constant $a = \sqrt{n (n +…
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…
Synchrotron radiation and pair creation of massless charges in magnetic field
D. V. Gal'tsov
We study the massless limit in synchrotron radiation and one-photon pair creation in magnetic field. In this limit Schwinger critical field tends to zero, so…
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…
