Ts. Biro et al., LYAPUNOV EXPONENT AND PLASMON DAMPING RATE IN NON-ABELIAN GAUGE-THEORIES, Physical review. D. Particles and fields, 52(2), 1995, pp. 1260-1266
We explain why the maximal positive Lyapunov exponent of classical SU(
N) gauge theory coincides with (twice) the damping rate of a plasmon a
t rest in the leading order of thermal gauge theory.
