摘要
We investigate fractional quantum Hall effect at finite temperature using a fermion Chern-Simons field theoretical approach. In the absence of impurity scattering, the essential aspects of fractional quantum Hall effect, such as the quantization of Hall conductance, as well as quasi-particle charge and statistics are unrenormalized by thermal fluctuations. On the other hand, we find that the low energy excitation spectrum at finite may undergo some qualitative changes as temperature raises. Possible experimental consequences are discussed.
