Non-Fermi-liquid fixed point in multi-orbital Kondo impurity model relevant for Hund's metals
Alen Horvat, Rok Zitko, Jernej Mravlje
The paper studies a three‑orbital Kondo‑Kanamori impurity model for Hund's metals and finds a non‑Fermi‑liquid two‑channel overscreened SU(3) fixed point that governs the intermedi…

Superconductivity in a unique type of copper oxide
W. M. Li, J. F. Zhao, L. P. Cao +18
The paper reports bulk superconductivity above 70 K in the cuprate Ba₂CuO₄₋y, which features unusually compressed CuO₆ octahedra that alter the orbital hierarchy and introduce thre…
