Direct phase-sensitive identification of a d-form factor density wave in underdoped cuprates
K. Fujita, M. H. Hamidian, S. D. Edkins +12
The identity of the fundamental broken symmetry (if any) in the underdoped cuprates is unresolved. However, evidence has been accumulating that this state may be an unconventional…
Visualizing the emergence of the pseudogap state and the evolution to superconductivity in a lightly hole-doped Mott insulator
Y. Kohsaka, T. Hanaguri, M. Azuma +3
Superconductivity emerges from the cuprate antiferromagnetic Mott state with hole doping. The resulting electronic structure is not understood, although changes in the state of oxy…
Charge dynamics of Ca_{2-x}Na_{x}CuO_{2}Cl_{2} as a correlated electron system with the ideal tetragonal lattice
K. Waku, T. Katsufuji, Y. Kohsaka +6
We report the reflectivity and the resistivity measurement of Ca_{2-x}Na_{x}CuO_{2}Cl_{2} (CNCOC), which has a single-CuO2-plane lattice with no orthorhombic distortion. The doping…
Imaging nano-scale electronic inhomogeneity in lightly doped Mott insulator Ca_{2-x}Na_{x}CuO_{2}Cl_{2}
Y. Kohsaka, K. Iwaya, S. Satow +4
The spatial variation of electronic states was imaged in the lightly doped Mott insulator Ca_{2-x}Na_{x}CuO_{2}Cl_{2} using scanning tunneling microscopy / spectroscopy (STM/STS).…
Angle-resolved photoemission spectroscopy of Na-doped Ca2CuO2Cl2 single crystals: Fingerprints of a magnetic insulator in a heavily underdoped superconductor
Y. Kohsaka, T. Sasagawa, F. Ronning +7
Electronic evolution from an antiferromagnet to a high-Tc superconductor is revealed by angle-resolved photoemission experiments on tetragonal Ca(1.9)Na(0.1)CuO(2)Cl(2) single crys…
