Strong electron correlations and ligand hybridization for altermagnetism
Byungkyun Kang, Anderson Janotti, Dai Q. Ho +5
Spin-band splitting is a hallmark of altermagnetism, intrinsically linked to magnetic ordering driven by electron correlations. However, recent inconsistencies in the detection of…

Hund's physics extends to actinide f electron systems
Byungkyun Kang, Roy N. Herrera-Navarro, Stephen S. Micklo +2
Uranium 5f electrons often yield heavy-fermion behavior via Kondo screening. However, the pronounced bad-metallic transport of uranium mononitride (UN) defies an incoherent Kondo e…

Lifshitz transition in correlated topological semimetals
Byungkyun Kang, Myoung-Hwan Kim, Chul Hong Park +2
Topological quasiparticles, arising when the chemical potential is near the band crossing, are pivotal for the development of next-generation quantum devices. They are expected to…
