摘要：

The critical behavior of sliding charge-density waves just above threshold is analyzed. In 4 - epsilon dimensions, the exponent-zeta, defined through I(CDW) is similar to (V - V(T)) zeta, is found to be 1 = epsilon/6 + O(epsilon-2). Two different correlation lengths are found, with exponents nu=1/2 exactly and nu(FS)=2/d + O(epsilon-2) compare favorably with recent numerical results in two and three dimensions.
