We study the conductivity tensor for the pure anyon system at finite temperature by calculating the electromagnetic response function Kμν(ω, k) in the random-phase approximation. We find that the conductivity is indeed infinite through the vanishing of the renormalized Chern-Simons term for the statistical gauge fields in the limit k=0, ω→0. To study the Meissner effect at finite temperature, others have looked at Kµν(ω, k) in the limit ω=0, k→0. We compare the results and make some comments.

Pair Plasma

The longitudinal dielectric response function of a relativistic gas consisting of charged bosons together with the corresponding antiparticles is obtained in the random phase approximation. The theory is renormalized and an analysis of the mode structure and damping properties of the plasma is carried out.
