Raman fingerprint of high-temperature superconductivity in compressed hydrides
Philip Dalladay-Simpson, Guglielmo Marchese, Zi-Yu Cao +5
The discovery of high-temperature superconductivity in hydrogen-rich compounds under extreme pressures has prompted great excitement, intense research, but also debate over the pas…
Spin-dependent anisotropic electron-phonon coupling in KTaO
Giulia Venditti, Francesco Macheda, Paolo Barone +2
KTaO (KTO) is an incipient ferroelectric, characterized by a softening of the lowest transverse optical (TO) mode with decreasing temperature. Cooper pairing in the recently di…
Infrared markers of topological phase transitions in quantum spin Hall insulators
Paolo Fachin, Francesco Macheda, Paolo Barone +1
Using first principles techniques, we show that infrared optical response can be used to discriminate between the topological and the trivial phases of two-dimensional quantum spin…
Magnetic interactions as a pivotal determinant in stabilizing a novel AgIIAgIIIF5 polymorph with high spin AgIII
Daniel Jezierski, Wojciech Grochala
Based on theoretical calculations, we introduce a new AgIIAgIIIF5 monoclinic polymorph with a rare high spin AgIII. Our analysis of the experimental xray diffraction data available…
How orbitals and oxidation states determine apparent topographies in scanning tunneling microscopy: the case of fluorine on silver surfaces
Adrián Gómez Pueyo, Jazmín Aragón Sánchez, Ilya Degtev +11
We use density functional theory calculations to characterize the early stages of fluorination of silver's (100) and (110) surfaces. In the Ag(100) surface, the hollow site is the…
