Field-induced asymmetric band flattening and ideal quantum geometry in rhombohedral graphene
Hongyun Zhang, Jinxi Lu, Size Wu +17
Rhombohedral graphene exhibits an exceptionally diverse array of correlated phases that depend sensitively on the displacement field. Compiling reported phases into a unified phase…
Robust topological surface states in skyrmion-host magnets Eu(Ga,Al)4: evidence for dual topology
Yuki Arai, Kosuke Nakayama, Takemi Kato +10
The interplay between real-space topology such as magnetic skyrmions and momentum-space topology characterized by topological surface states (TSSs) is predicted to realize novel ph…
Origin of multiple skyrmion phases in EuAl4
Y. Arai, K. Nakayama, A. Honma +6
The Dzyaloshinskii-Moriya (DM) interaction has been considered essential for skyrmion formation, however, the discovery of skyrmion lattices (SkLs) in nominally centrosymmetric mat…
Direct observation of band structure modifications from monolayer WSe2 to Janus WSSe
Masato Sakano, Shunsuke Akatsuka, Takato Yamamoto +19
Janus monolayer transition metal dichalcogenides (TMDs), created by post-growth substitution of the top chalcogen layer, represent a new direction for engineering 2D crystal proper…
Moiré enhanced flat band in rhombohedral graphene
Hongyun Zhang, Jinxi Lu, Kai Liu +17
The fractional quantum anomalous Hall effect (FQAHE) is a fascinating emergent quantum state characterized by fractionally charged excitations in the absence of magnetic field,whic…
Discovery of a Highly Anisotropic Type-II Ferromagnetic Weyl State Exhibiting a 3D Quantum Hall Effect
Yingdong Guan, Abhinava Chatterjee, Trace Bivens +13
Topological semimetals, particularly Weyl semimetals (WSMs), are crucial platforms for exploring emergent quantum phenomena due to their unique electronic structures and potential…
