Intrinsic in-plane nodal chain and generalized quaternion charge protected nodal link in photonics
Abstract Nodal lines are degeneracies formed by crossing bands in three-dimensional momentum space. Interestingly, these degenerate lines can chain together via touching points and manifest as nodal chains. These nodal chains are usually embedded in two orthogonal planes and protected by the corresp...
