Laser ARPES, the sudden approximation, and quasiparticle-like peaks in Bi2Sr2CaCu2O8+delta
J. D. Koralek, J. F. Douglas, N. C. Plumb +9
A new low photon energy regime of angle resolved photoemission spectroscopy is accessed with lasers and used to study the superconductor Bi2Sr2CaCu2O8+delta. The low energy increas…
Vortices and Superfluidity in a Strongly Interacting Fermi Gas
M. W. Zwierlein, J. R. Abo-Shaeer, A. Schirotzek +2
Quantum-degenerate Fermi gases provide a remarkable opportunity to study strongly interacting fermions. In contrast to other Fermi systems, such as superconductors, neutron stars o…
Abrupt transition in quasiparticle dynamics at optimal doping in a cuprate superconductor system
N. Gedik, J. Orenstein, S. Ono +2
We report time-resolved measurements of the photoinduced change in reflectivity, Delta R, in the Bi2Sr2Ca(1-y)Dy(y)Cu2O(8+delta) (BSCCO) system of cuprate superconductors as a func…
A `checkerboard' electronic crystal state in lightly hole-doped Ca_{2-x}Na_{x}CuO_{2}Cl_{2}
T. Hanaguri, C. Lupien, Y. Kohsaka +5
The phase diagram of hole-doped copper oxides shows four different electronic phases existing at zero temperature. Familiar among these are the Mott insulator, high-transition-temp…
Doping effects on the electronic and structural properties of CoO2: An LSDA+U study
Peihong Zhang, Weidong Luo, Vincent H. Crespi +2
A systematic LSDA+U study of doping effects on the electronic and structural properties of single layer CoO2 is presented. Undoped CoO2 is a charge transfer insulator within LSDA+U…
Inhomogeneity in doped Mott insulator
Dung-Hai Lee
We introduce the concept that there are two generic classes of Mott insulators in nature. They are distinguished by their responses to weak doping. Doped charges form cluster (i.e.…
