Electron correlation and Fermi surface topology of Na $_{x}$ CoO $_{2}$

Sen Zhou, Meng Gao, Hong Ding +2

The electronic structure of Na $_{x}$ CoO $_{2}$ revealed by recent photoemission experiments shows important deviations from band theory predictions. The six small Fermi surface pockets…

Edge-currents in superconductors with a broken time-reversal symmetry

Bernd Braunecker, Patrick A. Lee, Ziqiang Wang

We analyze edge currents and edge bands at the surface of a time-reversal symmetry breaking d_{x^2-y^2}+id_{xy} superconductor. We show that the currents have large Friedel oscilla…

ARPES on Na $_{0.6}$ CoO $_{2}$ : Fermi surface, extended flat dispersion, and unusual band splitting

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

The electronic structure of single crystals Na $_{0.6}$ CoO $_{2}$ , which are closely related to the superconducting Na $_{0.3}$ CoO $_{2}$ . $y$ H $_{2}$ O ( $T_{c} \sim 5 K$ ), is studied by angle-res…

Instabilities Toward Charge Density Wave and Paired Quantum Hall State of Half-Filled Landau Levels

Ziqiang Wang

We study the stability of spin-resolved Landau levels at electron filling factor $ν = n + 1/2$ , where n is a positive integer. Representing the half-filled topmost Landau level by ferm…
