Pseudogap Suppression by Competition with Superconductivity in La-Based Cuprates
J. Küspert, R. Cohn Wagner, C. Lin +23
We have carried out a comprehensive high-resolution angle-resolved photoemission spectroscopy (ARPES) study of the pseudogap interplay with superconductivity in La-based cuprates.…
Imaging Se diffusion across the FeSe/SrTiO interface
Samantha O'Sullivan, Ruizhe Kang, Jules A. Gardener +3
Monolayer FeSe on SrTiO superconducts with reported as high as 100 K, but the dramatic interfacial enhancement remains poorly understood. Oxygen v…
High-Temperature Charge-Stripe Correlations in LaEuSrCuO
Qisi Wang, M. Horio, K. von Arx +24
We use resonant inelastic x-ray scattering to investigate charge-stripe correlations in LaEuSrCuO. By differentiating elastic from inelastic scatter…
Decoupling of Lattice and Orbital Degrees of Freedom in an Iron-Pnictide Superconductor
Christian E. Matt, O. Ivashko, M. Horio +16
The interplay of structural and electronic phases in iron-based superconductors is a central theme in the search for the superconducting pairing mechanism. While electronic nematic…
Three-Dimensional Fermi Surface of Overdoped La-Based Cuprates
M. Horio, K. Hauser, Y. Sassa +24
We present a soft x-ray angle-resolved photoemission spectroscopy study of the overdoped high-temperature superconductors LaSrCuO and LaEuSrCu…
Direct Observation of Orbital Hybridisation in a Cuprate Superconductor
Christian E. Matt, D. Sutter, A. M. Cook +23
The minimal ingredients to explain the essential physics of layered copper-oxide (cuprates= materials remains heavily debated. Effective low energy single-band models of the copper…
Damped spin excitations in a doped cuprate superconductor with orbital hybridization
O. Ivashko, N. E. Shaik, X. Lu +13
A resonant inelastic x-ray scattering (RIXS) study of overdamped spin-excitations in slightly underdoped LaSrCuO (LSCO) with and is presented. Th…
Momentum-Resolved Electronic Structure of the High- Superconductor Parent Compound BaBiO
N. C. Plumb, D. J. Gawryluk, Y. Wang +12
We investigate the band structure of BaBiO, an insulating parent compound of doped high- superconductors, using \emph{in situ} angle-resolved photoemission spectroscop…
A resonant inelastic x-ray scattering study of the spin and charge excitations in the overdoped superconductor La1.77Sr0.23CuO4
C. Monney, T. Schmitt, C. E. Matt +5
We present a resonant inelastic x-ray scattering (RIXS) study of spin and charge excitations in overdoped La1.77Sr0.23CuO4 along two high-symmetry directions. The line shape of the…
High-temperature superconductivity from fine-tuning of Fermi-surface singularities in iron oxypnictides
A. Charnukha, D. V. Evtushinsky, C. E. Matt +6
In the family of the iron-based superconductors, the FeAsO-type compounds (with being a rare-earth metal) exhibit the highest bulk superconducting transition temperatures…
Electron scattering, charge order, and pseudogap physics in LaNdSrCuO: An angle resolved photoemission spectroscopy study
Christian E. Matt, Claudia G. Fatuzzo, Y. Sassa +27
We report an angle-resolved photoemission study of the charge stripe ordered LaNdSrCuO system. A comparative and quantitative line shape analysis is prese…
