    Upper bound estimated for Weyl points from multifold degeneracies

    What the study found The study finds an upper bound on the number of Weyl points, meaning generic twofold energy-degeneracy points, that can arise when a multifold degeneracy point in a quantum system is perturbed. Why the authors say this matters The authors say their work helps connect physics and mathematics by using singularity theory…
