摘要：

It is demonstrated that the spatial decay of the pair propagator in a Luttinger liquid with spin-charge separation contains a logarithmic correction relative to the free-Fermi-gas result in a finite interval between the spin and charge thermal lengths. It is argued that similar effects can be expected in higher-dimensional systems with spin-charge separation and that the temperature dependence of the upper critical field Hc2 curve is a probe of this effect. © 1994 The American Physical Society.
