Accidental and symmetry-protected bound states in the continuum in planar photonic-crystal structures, studied by the resonant-state expansion
Sam Neale, Egor Muljarov
The resonant-state expansion (RSE) provides a precise and computationally cheap tool to find resonant states in complex systems using the optical modes of a simpler system as a bas…

Resonant-state expansion for planar photonic-crystal structures
Sam Neale, Egor Muljarov
We present a new paradigm in the field of photonic crystals and metamaterials, applying the resonant-state expansion (RSE) to planar photonic-crystal structures. The RSE allows us…

Flow of S-matrix poles for elementary quantum potentials
B. Belchev, S. G. Neale, M. A. Walton
The poles of the quantum scattering matrix (S-matrix) in the complex momentum plane have been studied extensively. Bound states give rise to S-matrix poles, and other poles corresp…
