Proton distribution visualization in perovskite nickelate devices utilizing nanofocused X-rays
Ivan A. Zaluzhnyy, Peter O. Sprau, Richard Tran +17
We use a 30-nm x-ray beam to study the spatially resolved properties of a SmNiO-based nanodevice that is doped with protons. The x-ray absorption spectra supported by density-f…
Severe Dirac Mass Gap Suppression in Sb_2Te_3-based Quantum Anomalous Hall Materials
Yi Xue Chong, Xiaolong Liu, Rahul Sharma +5
Quantum anomalous Hall (QAH) effect appears in ferromagnetic topological insulators (FMTI) when a Dirac mass gap opens in the spectrum of the topological surface states (SS). Unacc…
Multi-Atom Quasiparticle Scattering Interference for Superconductor Energy-Gap Symmetry Determination
Rahul Sharma, Andreas Kreisel, Miguel Antonio Sulangi +10
Complete theoretical understanding of the most complex superconductors requires a detailed knowledge of the symmetry of the superconducting energy-gap , for all mom…
Imaging Orbital-selective Quasiparticles in the Hund's Metal State of FeSe
Andrey Kostin, Peter O. Sprau, Andreas Kreisel +6
Strong electronic correlations, emerging from the parent Mott insulator phase, are key to copper-based high temperature superconductivity (HTS). By contrast, the parent phase of ir…
Orbital superconductivity, defects and pinned nematic fluctuations in the doped iron chalcogenide FeSeTe
Saheli Sarkar, John Van Dyke, Peter Sprau +5
We demonstrate that the differential conductance, , measured via spectroscopic imaging scanning tunneling microscopy in the doped iron chalcogenide FeSeTe,…
Orbital selective pairing and gap structures of iron-based superconductors
Andreas Kreisel, Brian M. Andersen, Peter O. Sprau +3
We discuss the influence on spin-fluctuation pairing theory of orbital selective strong correlation effects in Fe-based superconductors, particularly Fe chalcogenide systems. We pr…
Discovery of Orbital-Selective Cooper Pairing in FeSe
Peter O. Sprau, Andrey Kostin, Andreas Kreisel +7
The superconductor FeSe is of intense interest thanks to its unusual non-magnetic nematic state and potential for high temperature superconductivity. But its Cooper pairing mechani…
Imaging atomic-scale effects of high-energy ion irradiation on superconductivity and vortex pinning in Fe(Se,Te)
Freek Massee, Peter Oliver Sprau, Yong-Lei Wang +4
Maximizing the sustainable supercurrent density, Jc, is crucial to high current applications of superconductivity and, to achieve this, preventing dissipative motion of quantized v…
