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…

Generalized Non-Hermitian Hamiltonian for Guided Resonances in Photonic Crystal Slabs
Viet Anh Nguyen, Hung Son Nguyen, Zhiyi Yuan +6
We develop a generalized non-Hermitian Hamiltonian formalism for guided resonances in photonic crystal slabs, derived directly from Maxwell's equations through a systematic guided-…
