Experimental observation of optical Weyl points
Jiho Noh, Sheng Huang, Daniel Leykam +3
Weyl fermions are hypothetical two-component massless relativistic particles in three-dimensional (3D) space, proposed by Hermann Weyl in 1929. Their band-crossing points, called '…
Edge Solitons in Nonlinear Photonic Topological Insulators
Daniel Leykam, Y. D. Chong
We show theoretically that a photonic topological insulator can support edge solitons that are strongly self-localized and propagate unidirectionally along the lattice edge. The ph…
Conical intersections for light and matter waves
Daniel Leykam, Anton S. Desyatnikov
We review the design, theory, and applications of two dimensional periodic lattices hosting conical intersections in their energy-momentum spectrum. The best known example is the D…
Anomalous Topological Phases and Unpaired Dirac Cones in Photonic Floquet Topological Insulators
Daniel Leykam, M. C. Rechtsman, Y. D. Chong
We propose a class of photonic Floquet topological insulators based on staggered helical lattices and an efficient numerical method for calculating their Floquet bandstructure. The…
