摘要：

We provide a theoretical basis for Clark's proposal that for quantum Hall liquids at magic filling factors, where the longitudinal conductivity is exponentially activated, sigma(xx) = sigma(xx)e0-DELTA/k(B)T, the prefactor sigma(xx)0 is proportional to the square of the quasiparticle charge. We also propose that the same experiments uncover a remarkable law of corresponding states.
