SUMMARY:Magnetic reconnection under the microscope: 3D PIC simulations
  of reconnecting current sheets\, Plasma Physics (Physics/ECE/NE 922) 
 Seminar\, Dr. Ari Le\, Los Alamos National Laboratory
DESCRIPTION:Magnetic reconnection under the microscope: 3D PIC simulat
 ions of reconnecting current sheets<br>
\n<br>
\nReconnection allows t
 he explosive release of magnetic energy stored in plasma currents. In 
 space plasmas\, reconnection depends on the smallest electron kinetic 
 scales. Numerical simulations\, observations by NASA’s MMS spacecraf
 t\, and laboratory experiments have now all delved into these fine det
 ails. Here\, recent 3D fully kinetic particle-in-cell (PIC) calculatio
 ns are presented. For systems based on MMS observations of the Earthâ€
 ™s magnetopause\, the lower hybrid drift instability (LHDI) drives ano
 malous particle transport. LHDI\, however\, does not significantly inc
 rease the reconnection rate. For conditions similar to Earth’s magne
 totail\, long electron current sheets supported by electron pressure a
 nisotropy develop. The electron pressure anisotropy drives an electrom
 agnetic instability that modulates the current density on small scales
 . The general structure of the extended electron current layer is neve
 rtheless preserved\, and it should therefore persist long enough to be
  observed both in space observations and in laboratory experiments suc
