SUMMARY:Coherent structures and magnetic reconnection in collisionless
  turbulence from the perspective of kinetic particle simulations\, Pla
 sma Physics (Physics/ECE/NE 922) Seminar\, Vadim Roytershteyn\, Space 
 Science Institute
DESCRIPTION:Plasma turbulence is one of the most ubiquitous processes 
 in laboratory\, space\, and astrophysical plasmas. Dissipation of turb
 ulent energy is thought to play an important role in the energy balanc
 e of many systems\, including the solar corona and the solar wind. In 
 contrast to the relatively simple physics of dissipation in fluids and
  collisional plasmas\, numerous microscopic processes can produce effe
 ctive dissipation in weakly collisional plasmas. The problem of identi
 fying and quantifying these processes has attracted considerable atten
 tion in the last decade partially because of its significance for unde
 rstanding energy partition in the corona and solar wind. In this talk\
 , we will describe some of the recent advances enabled by applications
  of kinetic particle computer simulations to this problem. Specificall
 y\, we will focus on generation of coherent structures by turbulence a
 nd on the contribution of magnetic reconnection to the energy dissipat
 ion.
