WebTriple nodal points are degeneracies of energy bands in momentum space at which three Hamiltonian eigenstates coalesce at a single eigenenergy. For spinless particles, the stability of a triple nodal point requires two ingredients: rotational symmetry of order three, four, or six; combined with mirror or space-time-inversion symmetry. However, despite … Web8 de fev. de 2024 · The higher-order nodal point has been discovered in several materials, like blue phosphorene oxide [ 12 ], monolayer Mg 2C [ 13 ]. Recently, Wu et al did a systematic study about the higher-order nodal point in spinless/spinful 2D systems [ 14 ]. Currently, it is desired to search for ideal 2D candidate materials with nodal points.

Web13 de abr. de 2024 · In this paper, an enriched reproducing kernel particle method combined with stabilized conforming nodal integration (SCNI) is proposed to tackle material interface problems. Regarding the domain integration, the use of SCNI offers an effective NI technique and eliminates the zero-energy modes which occurs to direct NI. To model … WebTwo Point Source Interference. Wave interference is a phenomenon that occurs when two waves meet while traveling along the same medium. The interference of waves causes the medium to take on a shape that results from the net effect of the two individual waves upon the particles of the medium. Wave interference can be constructive or destructive ...
