Nodal points are defined using parallel object and image rays at very small angles to the optical axis, and Johann Listing described them when characterizing the eye in 1845. They are only distinct from principal points when there is a refractive index difference, but Reginald Clay used the term “nodal slide” in 1904 for equipment that uses lens ...

Floquet multi-Weyl points in crossing-nodal-line semimetals [PDF]
Weyl points with monopole charge $\ifmmode\pm\else\textpm\fi{}1$ have been extensively studied; however, real materials of multi-Weyl points, whose monopole charges are higher than 1, have yet to be found.

IDENTIFICATION OF NODAL POINTS OF ELASTIC INCLUSION IN ELASTIC PLANE
Доклады Российской академии наук. Математика, информатика, процессы управления, 2023A geometric inverse problem of identifying an isotropic, linearly elastic inclusion in an isotropic, linearly elastic plane is considered. It is assumed that constant stresses are given at infinity, and the displacements and acting loads are known on some closed curve enclosing the inclusion.

Tunable Weyl Points in Periodically Driven Nodal Line Semimetals [PDF]
Weyl semimetals and nodal line semimetals are characterized by linear band touching at zero-dimensional points and one-dimensional lines, respectively. We predict that a circularly polarized light drives nodal line semimetals into Weyl semimetals.
