Chemical step drives droplet migration and spreading
—
in EngineeringWhat the study found The study found that droplets on a chemical step, a sharp border between two regions with different wettability, move in two successive stages: migration across both regions and then asymmetric spreading on the hydrophilic region. For both 2-D and 3-D droplets, the border can pin the rear contact line during the…
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…
