Analytically solving the magnetostatic Maxwell equations in the bispherical coordinates, we calculate the magnetic field around two uniformly magnetized spheres oriented so that th…
Spin-down of a pulsar with a yielding crust

In light of the discovery of the long-period radio pulsar PSR J0901-4046, it is interesting to revisit a question about how the magnetized neutron star slows down its rotation. In…
Perfect nonradiating electromagnetic source and its self-action
Denis Nikolaevich Sob'yanin
Nonradiating sources and anapoles are curious objects from the physics of invisibility that illuminate subtle concepts of fundamental electrodynamics and have promising application…

V. V. Belykh, D. N. Sob'yanin, A. R. Korotneva
Periodic excitation of electron spin polarization by consecutive laser pulses in phase with Larmor spin precession about a magnetic field results in resonant spin amplification (RS…
Extinct radio pulsars as a source of subrelativistic positrons
Ya. N. Istomin, D. O. Chernyshov, D. N. Sob'yanin
Extinct radio pulsars, in which stationary, self-sustaining generation of a relativistic electron-positron plasma becomes impossible when rotation brakes down, can be sources of a…

Denis Nikolaevich Sob'yanin
A recent discovery of the periodic activity of the repeating fast radio burst source FRB 180916.J0158+65 in the Canadian Hydrogen Intensity Mapping Experiment (CHIME) hints at poss…
Anomalous magnetic suppression of spin relaxation in a two-dimensional electron gas in a GaAs/AlGaAs quantum well
