Quasi-one-dimensional ballistic ring in the field of circularly polarized electromagnetic wave
E. M. Epshtein, E. G. Fedorov, G. M. Shmelev
Dynamics is studied of an electron in a quasi-one-dimensional ballistic ring under circularly polarized electromagnetic field propagating along the normal to the ring plane. The av…
Quasi-one-dimensional ballistic ring in crossed high-frequency electric fields
E. M. Epshtein, E. G. Fedorov, G. M. Shmelev
We study electron dynamics in a quasi-one-dimensional ballistic ring driven by two crossed high-frequency electric fields parallel to the ring plane. The averaged dipole moment and…
Hysteresis of static polarizability of a ballistic ring in presence of intense high-frequency field
E. M. Epshtein, G. M. Shmelev
A ballistic ring in presence of collinear dc and high-frequency electric fields is considered. A possibility is demonstrated of the system switching between two states by changing…
Helical structures in Seyfert galaxies
A. V. Moiseev, V. L. Afanasiev, S. N. Dodonov +2
The Seyfert galaxies with Z-shaped emission filaments in the Narrow Line Region (NLR) are considered. We assume that observable Z-shaped structures and velocity pattern of NLR may…
Stochastic spin evolution of neutron stars
S. B. Popov, M. E. Prokhorov, A. V. Khoperskov +1
In this paper we present calculations of period distribution for old accreting isolated neutron stars (INSs). At the age about a few billions years low velocity INSs come to the st…
The structure and kinematics of AGN with ionization cones
A. V. Moiseev, V. L. Afanasiev, S. N. Dodonov +2
Results of 2D spectral observations for 4 Sy galaxies with ionization cones are presented. Images in the [OIII] line, velocity fields of the ionized gas, stellar velocity and veloc…
