Electrical control of topological 3Q state in intercalated van der Waals antiferromagnet Cox-TaS2 Van der Waals (vdW) magnets have opened a new avenue of opportunities encompassing various interesting phases. Co1/3TaS2–an intercalated metallic vdW antiferromagnet–is one of the latest additions to this growi...

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...

DNA loop formation by structural maintenance of chromosome (SMC) proteins, including cohesin, condensin, and the SMC5/6 complex, plays a pivotal role in genome organization. Despite its importance, the molecular mechanism underlying SMC-mediated loop formation, particularly how these complexes achieve persistent direct...

Spin Dynamics of Triple-Q Magnetic Orderings in a Triangular Lattice: Implications for Multi-Q Orderings in General Two-Dimensional Lattices Multi-Q magnetic structures on two-dimensional (2D) lattices provide a key route to realizing topological physics in 2D magnetism. A major experimental challenge is to unambiguous...

We introduce a new dark matter detection mechanism, dark matter internal pair production (DIPP), to detect dark matter candidates at beam dump facilities. When energetic dark matter scatters in a material, it can create a lepton-antilepton pair by exchanging a virtual photon with the nucleus, akin to the neutrino tride...

MORC2 is a phosphorylation-dependent DNA compaction machine The Microrchidia (MORC) family of chromatin-remodelling ATPases is pivotal in forming higher-order chromatin structures that suppress transcription. The exact mechanisms of MORC-induced chromatin remodelling have been elusive. Here, we report an in vitro ...
