摘要：

It is shown that, within a Ginzburg-Landau (GL) formalism, the superconducting fluctuation is insulating at zero temperature even if the fluctuation dynamics is metallic (dissipative). Based on this result, the low-temperature behavior of the H-c2-line and the resistivity curves near a zero-temperature transition are discussed. In particular, it is pointed out that the neglect of quantum fluctuations in data analysis of the dc resistivity may lead to an underestimation of the H-c2 values near zero temperature.
