Non-Fermi liquid quasiparticles in strain-tuned Sr2RuO4
A. Hunter, C. Putzke, F. B. Kugler +23
Interacting electrons can form metallic states beyond the Fermi liquid paradigm, a conceptual frontier of many-body physics mainly explored via bulk thermodynamics and transport. I…
Fermi surface and pseudogap in highly doped SrIrO
Y. Alexanian, A. de la Torre, S. McKweon Walker +18
The fate of the Fermi surface in bulk electron-doped SrIrO remains elusive, as does the origin and extension of its pseudogap phase. Here, we use high-resolution angle-…
The fate of quasiparticles at high-temperature
A. Hunter, S. Beck, E. Cappelli +17
We study the temperature evolution of quasiparticles in the correlated metal SrRuO. Our angle resolved photoemission data show that quasiparticles persist up to temperature…
Electronic structure of the highly conductive perovskite oxide SrMoO
E. Cappelli, A. Hampel, A. Chikina +12
We use angle-resolved photoemission to map the Fermi surface and quasiparticle dispersion of bulk-like thin films of SrMoO grown by pulsed laser deposition. The electronic self…
Metal to insulator transition at the surface of thin films: an in-situ view
Marco Caputo, Jasmin Jandke, Edoardo Cappelli +12
has long been studied as a prototypical strongly correlated material. The difficulty in obtaining clean, well ordered surfaces, however, hindered the use of surface sensit…
Correlated electron metal properties of the honeycomb ruthenate NaRuO
L. S. I. Veiga, M. Etter, E. Cappelli +7
We report the synthesis and characterisation of polycrystalline NaRuO, a layered material in which the Ru ( configuration) form a honeycomb lattice. The optima…
Direct evidence for flat bands in twisted bilayer graphene from nano-ARPES
Simone Lisi, Xiaobo Lu, Tjerk Benschop +21
Transport experiments in twisted bilayer graphene revealed multiple superconducting domes separated by correlated insulating states. These properties are generally associated with…
A laser-ARPES study of LaNiO3 thin films grown by sputter deposition
Edoardo Cappelli, Willem Tromp, Siobhan McKeown Walker +4
Thin films of the correlated transition-metal oxide LaNiO undergo a metal-insulator transition when their thickness is reduced to a few unit cells. Here, we use angle-resolved…
High-resolution photoemission on Sr2RuO4 reveals correlation-enhanced effective spin-orbit coupling and dominantly local self-energies
A. Tamai, M. Zingl, E. Rozbicki +17
We explore the interplay of electron-electron correlations and spin-orbit coupling in the model Fermi liquid Sr2RuO4 using laser-based angle-resolved photoemission spectroscopy. Ou…
In-situ strain-tuning of the metal-insulator-transition of CaRuO in angle-resolved photoemission experiments
S. Riccò, M. Kim, A. Tamai +12
We report the evolution of the -space electronic structure of lightly doped bulk CaRuO with uniaxial strain. Using ultrathin plate-like crystals, we achieve strain l…
