A quantitative analysis of a recent model of high-temperature superconductors based on an interlayer tunneling mechanism is presented. This model can account well for the observed magnitudes of the high transition temperatures in these materials and implies a gap that does not change sign, can be substantially anisotropic, and has the same symmetry as the crystal. The experimental consequences explored so far are consistent with the observations. 

Interlayer Tunneling in High-Temperature Superconductors Beyond the Mean-Field Approximation

The interlayer tunneling in high-temperature superconductors has been reconsidered beyond the mean-field approximation. The modification of the quasiparticle spectrum originating from the

Experimental Constraints on the Theory of High-Tc Superconductivity

TLDR
To reconcile an apparent contradiction, a new type of electron liquid, called a Luttinger liquid, has been postulated, and the present article aims to show the need for this postulate.

Temperature dependence of the c-axis resistivity of high-Tc layered oxides.

TLDR
This calculation gives the same temperature dependence for the c-axis resistivity as that for the in-plane resistivity, and makes some definite predictions that can be put to test.
