Berry Monopole Scattering in the Synthetic Momentum Space of a Bilayer Photonic Crystal Slab

Ngoc Duc Le, D. -H. -Minh Nguyen, Dung Xuan Nguyen +2

Berry monopoles-quantized sources of Berry curvature-are fundamental to topological phases, yet their scattering remains unexplored. Here, we report for the first time the adiabati…
