Plasmas are ubiquitous in nature. Many astrophysical plasmas
(e.g. Solar wind, galactic cooling flows, some black hole accretion
disks and planetary magnetospheres) are observed or believed to be
almost collisionless as well as in a turbulent state. Under such
conditions, conventional fluid theories of plasma turbulence and
dissipation become questionable. We provide a general overview of the
field and discuss some of the recent results related to dissipation in
collisionless plasmas, transition of turbulence from fluid to kinetic
regimes as well as some astrophysical applications. |
