GENERAL RELATIVISTIC PLASMA PHYSICS
Primordial cosmological plasmas as well as plasmas around blackholes are
severely influenced by warped spacetime due to general relativistic
effects. The former is primarily in time and the latter primarily in
space. In order to make sufficient concrete progress in analyzing these
plasma phenomena, we developed a theoretical framework of plasma physics
based on Thorne and McDonalds' "3 + 1 formalism." (Publication #130, 1989). Application of this technique to
the black hole atmosphere has been carried out, finding (i) existence of
steady matter flows even within the 3 Schwarzschild radii (Rs)
(which has been thought to support no such thing before), (ii) a series
of new topological equilibria of plasmas with or without magnetic fields
near the blackhole (Tarkenton Ph.D. thesis 1996, supervised by Tajima).
A possible interpretation has been advanced to explain gamma ray bursts
using the stored matter within 3 Rs and its sudden in fall by
instability due to the enhanced plasma viscosity (Publication #227). High frequency electromagnetic waves
in the blackhole atmosphere have been also analyzed. We found that the
general relativistic warping through the (lapse function) can lead to a
cut off, resonance, and transmission and mode-conversion of such waves
solely due to the general relativistic effect. We also pointed out in
connection to the laser wakefield accelerator the
immense accelerating gradient in this can manifest strong general
relativistic effects such as laser spectral shift reminiscent of the
Sachs-Wolfe effect on cosmology.
