The non-zero temperature theory for non-interacting anyon gas is developed within the random-phase approximation. It is proved that the phase transition superconducting normal state of anyons does not occur and the Meissner effect disappears at non-zero temperatures. The mutual correspondence of new Haldane theory of anyons and mean field treatment is found. A short overview of the fractional statistics theory is also given. |
