Resolving unoccupied electronic states with laser ARPES in bismuth-based cuprate superconductors
Tristan L Miller, Minna Ärrälä, Christopher L. Smallwood +11
Angle-resolved photoemission spectroscopy (ARPES) is typically used to study only the occupied electronic band structure of a material. Here we use laser-based ARPES to observe a f…
The high-energy anomaly in ARPES spectra of the cuprates-many body or matrix element effect?
E. D. L. Rienks, M. Ärrälä, M. Lindroos +5
We used polarization-dependent angle-resolved photoemission spectroscopy (ARPES) to study the high-energy anomaly (HEA) in the dispersion of Nd2-xCexCuO4, (x=0.123). We have found…
Reply to Comment on Circular Dichroism in the Angle-Resolved Photoemission Spectrum of the High-Temperature Bi2Sr2CaCu2O8 Superconductor http://arxiv.org/abs/1004.1648
Matti Lindroos, Ville Arpiainen, Arun Bansil
We conclude that arguments of Norman et al. in their Comment do not provide a significant basis for their claim that the geometric mechanism for explaining the observations reporte…
Existence, character and origin of surface-related bands in the high temperature iron pnictide superconductor BaFe_{2-x}Co_{x}As_{2}
Erik van Heumen, Johannes Vuorinen, Klaus Koepernik +8
Low energy electron diffraction (LEED) experiments, LEED simulations and finite slab density functional calculations are combined to study the cleavage surface of Co doped BaFe_{2-…
Uniaxial "nematic-like" electronic structure and Fermi surface of untwinned CaFe2As2
Qiang Wang, Zhe Sun, Eli Rotenberg +8
Obtaining the electronic structure of the newly discovered iron-based superconductors is the key to understanding the mechanism of their high-temperature superconductivity. We used…
Origin of the high-energy kink or the waterfall effect in the photoemission spectrum of the high-temperature superconductor
Susmita Basak, Tanmoy Das, Hsin Lin +4
The high-energy kink or the waterfall effect seen in the photoemission spectra of the cuprates is suggestive of the coupling of the quasiparticles to a high energy bosonic mode wit…
