Plasma sheet structure in the magnetotail: kinetic simulation and comparison with satellite observations [PDF]

, 2003
We use the results of a three-dimensional kinetic simulation of an Harris current sheet to propose an explanation and to reproduce the ISEE-1/2, Geotail, and Cluster observations of the magnetotail current sheet structure. Current sheet flapping, current

“Matreshka” model of multilayered current sheet [PDF]

Geophysical Research Letters, 2006
Current sheets are one of the key elements of the Earth's magnetosphere, determining the magnetic energy storage and release. An analytical self‐consistent model of multicomponent thin current sheets, where the plasma consists of ions of both solar wind and ionospheric origin, is presented. The influence of the electron population is taken into account

Large Predicted Self-Field Critical Current Enhancements In Superconducting Strips Using Magnetic Screens

, 1999
A transport current distribution over a wide superconducting sheet is shown to strongly change in a presence of bulk magnetic screens of a soft magnet with a high permeability. Depending on the geometry, the effect may drastically suppress or protect the

Current‐driven instabilities in forced current sheets [PDF]

Journal of Geophysical Research: Space Physics, 2004
The nonlocal kinetic linear stability analysis of the non‐Harris thin current sheet equilibrium, namely the thin current sheet embedded in a thicker anisotropic plasma sheet [Sitnov et al., 2000a, 2000b], with respect to current‐driven instabilities is performed using the finite element technique.

Particle acceleration in axisymmetric pulsar current sheets

, 2015
The equatorial current sheet in pulsar magnetospheres is often regarded as an ideal site for particle acceleration via relativistic reconnection. Using 2D spherical particle-in-cell simulations, we investigate particle acceleration in the axisymmetric ...

Current sheet formation and nonideal behavior at three-dimensional magnetic null points [PDF]

, 2007
The nature of the evolution of the magnetic field, and of current sheet formation, at three-dimensional (3D) magnetic null points is investigated. A kinematic example is presented which demonstrates that for certain evolutions of a 3D null (specifically ...

Quasi‐adiabaticity in bifurcated current sheets [PDF]

Geophysical Research Letters, 2006
We examine the non‐linear dynamics of charged particles in “bifurcated” (double‐humped) current sheets. We show that, when the adiabaticity parameter κ is of the order unity, particles experience a negligible change of magnetic moment. Such a behavior contrasts with the prominent magnetic moment scattering that is achieved in single‐humped current ...

Cluster as current sheet surveyor in the magnetotail [PDF]

Annales Geophysicae, 2013
A novel analysis technique is presented to estimate the current sheet thickness unambiguously and directly, without associating time series data with spatial structure.

Optimal Energy Growth in Current Sheets [PDF]

Solar Physics, 2017
In this paper, we investigate the possibility of transient growth in the linear perturbation of current sheets. The resistive magnetohydrodynamic (MHD) operator for a background field consisting of a current sheet is non-normal, meaning that associated eigenvalues and eigenmodes can be very sensitive to perturbation. In a linear stability analysis of a
