Tuning orbital-selective phase transitions in a two-dimensional Hund’s correlated system

Nature Communications, 2023
Hund’s rule coupling (J) has attracted much attention recently for its role in the description of the novel quantum phases of multi-orbital materials. Depending on the orbital occupancy, J can lead to various intriguing phases.
