Comment on: Role of inelastic tunneling through the insulating barrier in scanning-tunneling-microscope experiments on cuprate superconductors
A. R. Bishop, S. D. Conradson, A. Bussmann-Holder +7
In a recent letter [1] Pilgram, Rice and Sigrist (PRS) propose to perform oxygen isotope dependent conductivity measurements along the c-axis of the cuprate superconductor BSSCO. I…

Interplay between proton ordering and ferroelectric polarization in H-bonded KDP-type crystals
S. Koval, J. Kohanoff, R. L. Migoni +1
The origin of ferroelectricity in KH_2PO_4 (KDP) is studied by first-principles electronic structure calculations. In the low-temperature phase, the collective off-center ordering…
