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…
