Anisotropic softening of collective charge modes in the vicinity of critical doping in a doped Mott insulator
Y. W. Li, D. Qian, L. Wray +9
Momentum resolved inelastic resonant x-ray scattering is used to map the evolution of charge excitations over a large range of energies, momenta and doping levels in the electron d…
Nature of Correlated Motion of Electrons in the Parent Cobaltate Superconductors
M. Z. Hasan, D. Qian, Y. Li +5
Recently discovered class of cobaltate superconductors (Na0.3CoO2.nH2O) is a novel realization of interacting quantum electron systems in a triangular network with low-energy degre…
Asymmetries in the electron-hole pair dynamics and strong Mott pseudogap effect in the phase diagram of cuprates
M. Z. Hasan, Y. Li, D. Qian +6
Electron behavior in doped Mott systems continues to be a major unsolved problem in quantum many-electron physics. A central issue in understanding the universal Mott behavior in a…
Fermi surface and quasiparticle dynamics of Na(x)CoO2 {x=0.7} investigated by Angle-Resolved Photoemission Spectroscopy
M. Z. Hasan, Y. -D. Chuang, A. P. Kuprin +13
We present an angle-resolved photoemission study of Na0.7CoO2, the host cobaltate of the NaxCoO2.yH2O series. Our results show a large hexagonal-like hole-type Fermi surface, an ex…
