Monolayer van der Waals kagome lattice for high-temperature flat-band physics
Hyungkun Bong, Choongjae Won, Seongyong Lee +26
Kagome lattice materials host a remarkably rich landscape of novel quantum phenomena, all arising from the intrinsic interplay of topology, correlation, and frustration. While prev…

Polymorphic spin ordering in a single-crystalline cobalt-doped Fe3GaTe2
Woohyun Cho, Jaehun Cha, Yoon-Gu Kang +10
A single crystalline system typically stabilizes a unique state for spin ordering below a critical temperature. Certain materials exhibit multiple magnetic states, driven by struct…

Singular Hall response from a correlated ferromagnetic flat nodal-line semimetal
Woohyun Cho, Yoon-Gu Kang, Jaehun Cha +9
Topological quantum phases have been largely understood in weakly correlated systems, which have identified various quantum phenomena such as spin Hall effect, protected transport…
