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…
Two-dimensional type-II Dirac fermions in layered oxides
M. Horio, C. E. Matt, K. Kramer +11
Relativistic massless Dirac fermions can be probed with high-energy physics experiments, but appear also as low-energy quasi-particle excitations in electronic band structures. In…
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…
Orbital-selective metal skin induced by alkali-metal-dosing Mott-insulating CaRuO
M. Horio, F. Forte, D. Sutter +21
Doped Mott insulators are the starting point for interesting physics such as high temperature superconductivity and quantum spin liquids. For multi-band Mott insulators, orbital se…
Electronic reconstruction forming a -symmetric Dirac semimetal in CaRuO
M. Horio, Q. Wang, V. Granata +19
Electronic band structures in solids stem from a periodic potential reflecting the structure of either the crystal lattice or an electronic order. In the stoichiometric ruthenate C…
Oxide Fermi liquid universality revealed by electron spectroscopy
M. Horio, K. P. Kramer, Q. Wang +27
We present a combined soft x-ray and high-resolution vacuum-ultraviolet angle-resolved photoemission spectroscopy study of the electron-overdoped cuprate PrLaCe$_…
Hallmarks of Hund's coupling in the Mott insulator CaRuO
D. Sutter, C. G. Fatuzzo, S. Moser +22
A paradigmatic case of multi-band Mott physics including spin-orbit and Hund's coupling is realised in CaRuO. Progress in understanding the nature of this Mott insulating p…
Low Space-Charge Intensity Beams in UMER via Collimation and Solenoid Focusing
S. Bernal, B. Beaudoin, L. Dovlatyan +5
The University of Maryland Electron Ring (UMER) has operated traditionally in the regime of strong space-charge dominated beam transport, but small-current beams are desirable to s…
Optimization of Flat to Round Transformers with Self-fields using Adjoint Techniques
L. Dovlatyan, B. L. Beaudoin, S. Bernal +3
A continuous system of moment equations is introduced that models the transverse dynamics of a beam of charged particles as it passes through an arbitrary lattice of quadrupoles an…
Band Structure of Overdoped Cuprate Superconductors: Density Functional Theory Matching Experiments
K. P. Kramer, M. Horio, S. S. Tsirkin +25
A comprehensive angle resolved photoemission spectroscopy study of the band structure in single layer cuprates is presented with the aim of uncovering universal trends across diffe…
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.…
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…
