c-Axis Penetration Depth in the Cuprates: Additional Evidence for Incoherent Hopping
R. J. Radtke, V. N. Kostur
Measurements of the -axis penetration depth in the cuprates reveal a low-temperature dependence which is inconsistent with simple models of coupling between the CuO$_2…

Ultrasonic attenuation in d-wave superconductors
Vladimir N. Kostur, Jayanta K. Bhattacharjee, Richard A. Ferrell
The longitudinal ultrasonic attenuation at low temperatures for a -wave superconducting order parameter is examined. The ratio of the superconducting to normal state attenuation…
