Constructing massive particles surfaces in static spacetimes
Igor Bogush, Kirill Kobialko, Dmitri Gal'tsov
The procedure for constructing the massive particle surfaces in static space-times is described in detail and the equivalence of the main results with the results of the geodesic a…
Steering of vortices by magnetic-field tilting in superconductor nanotubes
Igor Bogush, Oleksandr V. Dobrovolskiy, Vladimir M. Fomin
In planar superconductor thin films, the places of nucleation and arrangements of moving vortices are determined by structural defects. However, various applications of superconduc…
Microwave generation and vortex jets in superconductor nanotubes
Igor Bogush, Oleksandr V. Dobrovolskiy, Vladimir M. Fomin
The dynamics of magnetic flux quanta (Abrikosov vortices) determine the resistive response of superconductors. In pinning-free planar thin films, the penetration and motion of vort…
Supergravity -branes with scalar charge
Igor Bogush, Dmitri Gal'tsov
Standard dilatonic supergravity -branes have scalar charges that are not independent parameters, but are determined by the brane tension and Page charges. This feature can be tr…
The geometry of massive particle surfaces
Kirill Kobialko, Igor Bogush, Dmitri Gal'tsov
We propose a generalization of Claudel, Virbhadra, and Ellis photon surfaces to the case of massive charged particles, considering a timelike hypersurface such that any worldline o…
