Observation of low energy dispersive modes in un- derdoped (La, Nd) 2--x Sr x CuO 4
Matteo D 'Astuto, Sylvain Denis, Jeff Graf +10
We find excitations lower in energy than known phonon modes in underdoped LaSrCuO (x=0.08), with both inelastic X-Ray scattering (IXS) and inelastic neutron…
Nodal quasiparticle meltdown in ultra-high resolution pump-probe angle-resolved photoemission
J. Graf, C. Jozwiak, C. L. Smallwood +4
High- cuprate superconductors are characterized by a strong momentum-dependent anisotropy between the low energy excitations along the Brillouin zone diagonal (nodal direction…
Crossover region between nodal and anti-nodal states at the Fermi level of optimally and overdoped BiSrNdCuO
D. R. Garcia, J. Graf, C. Jozwiak +3
We have studied BiSrNdCuO using Angle Resolved Photoemission Spectroscopy in the optimal and overdoped regions of the phase diagram. We identify a nar…
Bilayer splitting and c-axis coupling in bilayer manganites showing colossal magnetoresistance
C. Jozwiak, J. Graf, S. Y. Zhou +5
By performing angle-resolved photoemission spectroscopy of the bilayer colossal magnetoresistive (CMR) manganite, , we provide the complete mapping o…
A universal high energy anomaly in angle resolved photoemission spectra of high temperature superconductors - possible evidence of spinon and holon branches
J. Graf, G. -H. Gweon, K. McElroy +10
A universal high energy anomaly in the single particle spectral function is reported in three different families of high temperature superconductors by using angle-resolved photoem…
Nodal metallic behavior of lightly-doped LaSrCuO
T. Yoshida, X. J. Zhou, T. Sasagawa +10
Lightly-doped LaSrCuO in the so-called "insulating" spin-glass/diagonal-stripe phase has been studied by angle-resolved photoemission spectroscopy. A quasi-particle…
