Physical properties of the ferromagnetic quantum critical system ${\text{YbNi}}_{4}(\text{P}{}_{1\ensuremath{-}x}\text{As}{}_{x}{)}_{2}$
The heavy-fermion system YbNi4P${}_{2}$ is arguably the ferromagnetic (FM) metal with the lowest Curie temperature (${T}_{c}$=0.17 K). It has been shown that replacing P with As tunes this system to a...

Quantum geometry probed by chiral excitonic optical response of Chern insulators
Quantum geometry describes phase and amplitude distances between quantum states, akin to Euclidean geometry in the classical world. The authors propose here probing the quantum geometry of Chern insul...
