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…
Destruction of antinodal state coherence via `checkerboard' charge ordering in strongly underdoped superconducting BSCCO-2212
K. McElroy, D. -H. Lee, J. E. Hoffman +6
Microscopy (STM). At all dopings, the low energy density-of-states modulations are analyzed according to a simple model of quasiparticle interference and found to be consistent wit…
Homogenous nodal superconductivity coexisting with inhomogeneous charge order in strongly underdoped Bi-2212
K. McElroy, D. -H. Lee, J. E. Hoffman +6
We use novel STM techniques in concert to study the doping dependence of electronic structure in Bi-2212. At all dopings, the low energy states are relatively homogenous except for…
The Dichotomy between Nodal and Antinodal Quasiparticles in Underdoped (LaSr)CuO Superconductors
X. J. Zhou, T. Yoshida, D. -H. Lee +13
High resolution angle-resolved photoemission measurements on underdoped (LaSr)CuO system show that, at energies below 70 meV, the quasiparticle peak is well defined…
