Unconventional Mixed-Parity Magnetism in Rare-Earth Tetraborides
Dong-Choon Ryu, Jae-Ho Han, Bongjae Kim +1
Altermagnetism has advanced the study of compensated magnets by revealing non-relativistic spin splitting, traditionally classified into strictly even- or odd-parity spin textures.…
Weyl Fermion with various chiralities in a f-electron ferromagnetic system: PrB4
Dong-Choon Ryu, Junwon Kim, Kyoo Kim +3
Rare-earth tetraborides (B) have attracted a lot of recent attention due to their intriguing electronic, magnetic, and topological properties. We have theoretically invest…
Multiple topological Dirac cones in a mixed-valent Kondo semimetal: g-SmS
Chang-Jong Kang, Dong-Choon Ryu, Junwon Kim +5
We demonstrate theoretically that the golden phase of SmS (-SmS), a correlated mixed-valent system, exhibits nontrivial surface states with diverse topology. It turns out that t…
Topological Phase Transition in an Archetypal f-electron Correlated System: Ce
Junwon Kim, Dongchoon Ryu, Chang-Jong Kang +4
A typical f-electron Kondo lattice system Ce exhibits the well-known isostructural transition, the so-called gamma-alpha transition, accompanied by an enormous volume collapse. Mos…
