Interlayer tunneling models of cuprate superconductivity: Implications of a recent experiment

Research output: Contribution to journalArticlepeer-review

Abstract

It is shown that, given a few generic assumptions, any theory of high- temperature superconductivity that attributes a substantial fraction of the condensation energy to the saving of c-axis kinetic energy must predict an inequality relating the c-axis penetration depth λ1 (0) to the zero- temperature superconducting-normal energy difference and the fluctuations of the c-axis kinetic energy around its mean value. Application of this formula to Tl2Ba2CuO6 implies that if λ (0) is greater than 10 micrometers, as suggested by a recent experiment, these fluctuations must have an unusual form.
