Temperature dependence of nanoscale friction for Fe on YBCO
Igor Altfeder,Jacqueline Krim +1 more
TL;DR: In this article, a magnetic probe microscopy study of levitation and atomic-scale friction is reported for Fe on YBCO in the temperature range 65-293 K. The results indicate that contact electrification and static electricity may play a significant role in the non-superconducting phase.

Phonon thermal conductivity in doped La 2 CuO 4 : Relevant scattering mechanisms
TL;DR: In this article, in-plane and out-of-plane thermal-conductivity measurements on single crystals were performed and the most characteristic features of the temperature dependence are a pronounced phonon peak at low temperatures and a steplike anomaly at the transition to the low-temperature-tetragonal phase (LTT phase), which gradually decrease with increasing Sr content.

Quantum Oscillations in Hole-Doped Cuprates
TL;DR: In this article, a nodal electron pocket created by charge order is found to characterise the normal ground state in YBa2Cu3O6+x and is likely universal to a majority of the cuprate superconductors.

Pair Fermi contour and repulsion-induced superconductivity in cuprates
V. I. Belyavsky,Yu. V. Kopaev +1 more
TL;DR: In this article, the pairing of charge carriers with a large pair momentum is considered in connection with high-temperature superconductivity of cuprate compounds, and it is concluded that pairing in cuprates may be due to screened Coulomb repulsion.

Effect of impurities in high-symmetry lattice positions on the local density of states and conductivity of graphene
TL;DR: In this paper, the effect of an isolated impurity on the local electronic properties of a graphene monolayer, when the impurity is located on a sitelike, bondlike, or hollowlike position, was investigated.
