Tunable chiral and nematic states in the triple-Q antiferromagnet Co1/3TaS2 Complex spin configurations in magnetic materials, ranging from collinear single-Q to non-coplanar multi-Q states, exhibit rich symmetry and chiral properties. However, their detailed characterization is often hindered by the limited spa...

We report a three-terminal, ion-gel-gated, redox-active molecular transistor that exhibits synaptic plasticity and analog conductance states. The device was composed of a ferrocene-terminated alkanethiolate self-assembled monolayer as the active channel, vertically sandwiched between a monolayer graphene source and a A...

SrAs₃ hosts a single nodal ring in the Brillouin zone without interference from trivial bands around the Fermi level. Using high-field magneto-reflectivity, we tracked Landau-level transitions and revealed three types of low-energy quasiparticles in the single nodal ring. Based on the model calculations, we analyz...
