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…

Magnetic field in vacuum of quantum spinor matter induced by a cosmic string in three-dimensional space
Yu. I. Pylypchuk, P. O. Nakaznyi, O. V. Barabash +2
A linear magnetic topological defect (cosmic string) is modeled as a magnetic flux-carrying tube that is impenetrable to external spinor matter. The matter field is quantized in th…

Dependence of scalar matter vacuum energy, induced by a magnetic topological defect, on the coupling to space-time curvature
V. M. Gorkavenko, A. O. Zaporozhchenko, M. S. Tsarenkova
We considered the vacuum polarization of a quantized charged scalar matter field in the background of a topological defect modeled by a finite-thickness tube with magnetic flux ins…
