Coexistence of competing orders with two energy gaps in real and momentum space in high-Tc superconductor Bi2Sr2-xLaxCuO6+delta

J. -H. Ma, Z. -H. Pan, F. C. Niestemski +12

The superconducting phase of the high-Tc cuprates has been thought to be described by a single d-wave pairing order parameter. Recently, there has been growing evidence suggesting…

Correlating off-stoichiometric doping with nanoscale electronic disorder and quasiparticle interference pattern in high- superconductor BiSrCaCuO

Sen Zhou, Hong Ding, Ziqiang Wang

A microscopic theory is presented for the observed electronic disorder in superconducting BiSrCaCuO. The essential phenomenology is shown to be consistent with…

Electron correlation and Fermi surface topology of NaCoO

Sen Zhou, Meng Gao, Hong Ding +2

The electronic structure of NaCoO revealed by recent photoemission experiments shows important deviations from band theory predictions. The six small Fermi surface pockets…

Fermi surface topology of Ca_{1.5}Sr_{0.5}RuO_{4} determined by ARPES

S. -C. Wang, H. -B. Yang, A. K. P. Sekharan +11

We report ARPES results of the Fermi surface of Ca_{1.5}Sr_{0.5}RuO$_{4}, which is at the boundary of magnetic/orbital instability in the phase diagram of the Ca-substituted Sr rut…
