Impact of space-time curvature coupling on the vacuum energy induced by a magnetic topological defect in flat space-time of arbitrary dimension
V. M. Gorkavenko, O. V. Barabash, I. V. Ivanchenko +4
We have investigated vacuum polarization of a quantized charged massive scalar field in the presence of a magnetic topological defect, modeled as an impenetrable tube of finite thi…

Analytic calculation of dynamical friction for Plummer sphere in ultralight dark matter
O. V. Barabash, T. V. Gorkavenko, V. M. Gorkavenko +4
The dynamical friction force acting on a spatially extended probe (globular clusters and dwarf galaxies) moving in the environment of ultralight bosonic dark matter in the state of…
