Hc(2)(T) As A Probe of Anomalous Normal-State Correlations in Cuprates

Richardo Dias, Andrew Schofield, JM Wheatley

Research output: Contribution to journalArticlepeer-review


The temperature dependence of the upper critical field in a BCS superconductor directly reflects the assumed fermi liquid character of the normal state. In low Tc cuprates, where fluctuation effects are weak and the Hc2 line is experimentally accessible to low temperatures, the Hc2 curve can serve as a powerful probe of departures from fermi liquid theory, because it is sensitive to both the space and energy dependence of correlations. We present calculations which illustrate the effects of independent charge and spin velocity scales on the Hc2 line using (a) Luttinger liquid forms of the single electron green's function with spin-charge separation and (b) 2D gauge model approaches.
