Orbital-specific Itinerancy and Localization in a Kagome Magnet
S. V. Streltsov, H. Y. Huang, A. Ushakov +10
The kagome lattice naturally hosts flat bands, Dirac fermions, and van Hove singularities, yet whether its geometry can stabilize orbital-selective phases - a hallmark of Hund's ph…

Ising spin ladders of orthopyroxene CoGeO
Pavel A. Maksimov, Andrey F. Gubkin, Alexey V. Ushakov +6
We present thermodynamic and spectroscopic measurements for an orthopyroxene CoGeO with magnetic Co ions that form quasi-one-dimensional ladders. We show that non-collin…
