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…
Magnetic field dependence of the oxygen isotope effect on the magnetic penetration depth in hole-doped cuprate superconductors
R. Khasanov, A. Shengelaya, D Di Castro +7
The magnetic field dependence of the oxygen-isotope (^{16}O/^{18}O) effect (OIE) on the in-plane magnetic field penetration depth λ_{ab} was studied in the hole-doped high-temperat…
Real and marginal isotope effects in cuprate superconductors
A. R. Bishop, A. Bussmann-Holder, O. V. Dolgov +8
We critically review recent and earlier results on isotope effects in cuprate superconductors and emphasize that the sample preparation and the isotope exchange and back exchange a…
Coexistence of superconductivity and incoherence in quasi 1D chains
R. Khasanov, T. Kondo, J. Schmalian +7
The dimensionality of a correlated many-body system has a large impact on its electronic properties. When electrons are confined to one-dimensional chains of atoms their behavior i…
Dual character of the electronic structure in YBa2Cu4O8: conduction bands of CuO2 planes and CuO chains
T. Kondo, R. Khasanov, J. Karpinski +10
We use microprobe Angle-Resolved Photoemission Spectroscopy (muARPES) to separately investigate the electronic properties of CuO2 planes and CuO chains in the high temperature supe…
Correlation between oxygen isotope effects on the transition temperature and the magnetic penetration depth in high-temperature superconductors close to optimal doping
R. Khasanov, A. Shengelaya, K. Conder +4
The oxygen-isotope (^{16}O/^{18}O) effect (OIE) on the in-plane magnetic penetration depth λ_{ab}(0) in optimally-doped YBa_2Cu_3O_{7-δ} and La_{1.85}Sr_{0.15}CuO_4, and in slightl…
