3D study of centrifugal acceleration in isotropic photon fields

Abstract

In this paper we study relativistic dynamics of charged particles co-rotating with prescribed trajectories, having the shape of dipolar magnetic field lines. In particular, we consider the role of the drag force caused by the photon field the forming of equilibrium positions of the charged particles. Alongside a single particle approach we also study behaviour of ensemble of particles in the context of stable positions. As we have shown, together they create surfaces where particles are at stable equilibrium positions. In this paper we examine these shapes and study parameters they depend on. It has been found that under certain conditions there are two distinct surfaces with stable equilibrium positions.

Relativistic Effects of Rotation in γ-ray Pulsars—Invited Review

“…In this case, the particles do not tend to the force-free regime, but instead reach a certain equilibrium location. Similar results have been obtained for 3D configurations of the field lines (for details, the reader is referred to [30,31]). [28].…”

Dynamics of a particle in the generalised Ellis-Bronnikov wormhole on the rotating Archimede’s spiral

“…The motion of matter may be studied either as fluid dynamics of an ensemble of particles [8] or as dynamics of a single particle [9][10][11][12][13]. In this paper we will be examining motion of a charged particle in the presence of magnetic field.…”

“…Dynamics of particles on rotating channels has been studied in a series of papers [9][10][11][12][13][14]. Problem becomes interesting near the light cylinder (LC) region, where the velocity of rotation coincides with the speed of light.…”

“…However, in real astrophysical situations field lines are curvilinear as they tend to lag behind the rotation near the LC surface. We take special interest in field lines having the configuration of the Archimede's spiral, because, as it has been shown, the forcefree regime may be established, enabling particles to reach infinity with finite velocity [9,10].…”
