Building blocks of topological band theory for photonic crystals
Yoonseok Hwang, Vaibhav Gupta, Antonio Morales-Pérez +6
We derive a framework for classifying topological bands in three-dimensional photonic band structures, where the zero frequency polarization singularity implied by Maxwell's equati…
On the origin of the Kerker phenomena
Jon Lasa-Alonso, Chiara Devescovi, Carlos Maciel-Escudero +2
We provide an insight into the origin of the phenomena reported 40 years ago by Kerker, Wang and Giles (Journal of the Optical Society of America, 73, 6, pp. 765-767, (1983)). We s…
Axion Topology in Photonic Crystal Domain Walls
Chiara Devescovi, Antonio Morales-Pérez, Yoonseok Hwang +6
Axion insulators are 3D magnetic higher-order topological insulators protected by inversion-symmetry that exhibit hinge-localized chiral channels and induce quantized topological m…
Transversality-Enforced Tight-Binding Models for 3D Photonic Crystals aided by Topological Quantum Chemistry
Antonio Morales-Pérez, Chiara Devescovi, Yoonseok Hwang +5
Tight-binding models can accurately replicate the band structure and topology of crystalline systems. They have been widely used in solid-state physics due to their versatility and…
Resonant helicity mixing of electromagnetic waves propagating through matter
Jon Lasa-Alonso, Jorge Olmos-Trigo, Chiara Devescovi +3
Dual scatterers preserve the helicity of an incident field, whereas antidual scatterers flip it completely. In this setting of linear electromagnetic scattering theory, we provide…
Vectorial Bulk-Boundary Correspondence for 3D Photonic Chern Insulators
Chiara Devescovi, Mikel Garcia-Diez, Barry Bradlyn +3
In 2D Chern insulators (2D CI), the topology of the bulk states is captured by a topological invariant, the Chern number. The scalar bulk-boundary correspondence (sBBC) relates the…
