Generalization of interlayer tunneling models to cuprate superconductors with charge density waves

Since the discovery of cuprate superconductors, the interlayer tunneling (ILT) and Lawrence-Doniach (LD) models, which connect CuO planes by Josephson coupling, were considered the leading theoretical proposals for these materials. However, measurements of the interlayer magnetic penetration depth lambda c yielded larger values than required by the ILT model. After the discovery of planar stripes and incommensurate charge ordering, it was also possible to consider Josephson coupling between these mesoscopic charge domains or blocks. We show that the average intralayer is larger than the interlayer coupling and is comparable with the condensation energy, leading to a superconducting transition by long-range phase order. Another consequence is that the ratio [lambda c/lambda ab]2 is related to the resistivity ratio pc/pab near the superconducting transition temperature, in agreement with several measurements.
