Constructing mode-resolved quantum optical models for emitters in photonic crystals
Antonio Morales-Pérez, Iñaki García-Elcano, Chiara Devescovi +3
Recent advances are enabling quantum emitters to interact with photonic crystals, whose electromagnetic modes exhibit complex dispersion relations, spatial mode structure, and pola…
Observation of ring states in a delicate topological insulator
Caroline Tornow, Julia Rupprecht, Pascal Engeler +4
Topological insulators are typically characterized by particularly stable properties, such as global invariants, and can be identified by probing their robust surface states. A rec…
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…
Design and characterization of all two-dimensional fragile topological bands
Samuel Bird, Chiara Devescovi, Pascal Engeler +5
Designing topological materials with specific topological indices is a complex inverse problem, traditionally tackled through manual, intuition-driven methods that are neither scal…
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…
Fermi arc reconstruction in synthetic photonic lattice
D. -H. -Minh Nguyen, Chiara Devescovi, Dung Xuan Nguyen +2
The chiral surface states of Weyl semimetals have an open Fermi surface called Fermi arc. At the interface between two Weyl semimetals, these Fermi arcs are predicted to hybridize…
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…
Cubic 3D Chern photonic insulators with orientable large Chern vectors
Chiara Devescovi, Mikel García-Díez, Iñigo Robredo +5
Time Reversal Symmetry (TRS) broken topological phases provide gapless surface states protected by topology, regardless of additional internal symmetries, spin or valley degrees of…
Tutorial: Computing topological invariants in two-dimensional photonic crystals
María Blanco de Paz, Chiara Devescovi, Geza Giedke +5
The field of topological photonics emerged as one of the most promising areas for applications in transformative technologies: possible applications are in topological lasers or qu…
