Two-dimensional chiral Weyl points in an interlaced Kagome layer

Weyl points (WPs) have attracted widespread discussion in three-dimensional (3D) systems owing to their distinctive topological properties, yet the pursuit of two-dimensional (2D) WPs remains a formidable challenge. In electronic systems, 2D WPs are inherently fragile due to spin-orbit coupling, while photonic implementations typically rely on synthetic dimensions, resulting in only quasi-3D WPs. Here, we demonstrate genuine 2D WPs in an interlaced woven Kagome layer, where the out-of-plane braiding breaks inversion and mirror symmetries while preserving the layer-group symmetry LG 76 (p622) that pins chiral linear crossings at the Brillouin-zone vertices. By controlled stretching of one family of rods, we reduce the symmetry to a lower subgroup and directly track the motion of the WPs. The associated edge spectra reveal a controllable evolution from Weyl-connecting gapless states to a gapped valley-topological phase after full symmetry lifting. This work establishes a mechanically tunable platform for intrinsic 2D Weyl physics and reconfigurable topological wave transport.
