Singular knot bundle in light
Danica Sugic, Mark R. Dennis
As the size of an optical vortex knot, imprinted in a coherent light beam, is decreased, nonparaxial effects alter the structure of the knotted optical singularity. For knot struct…
Composite Skyrmion bags in two-dimensional materials
David Foster, Charles Kind, Paul J. Ackerman +3
Skyrmions are particle-like topological excitations, studied in various condensed matter systems and models of high-energy physics (HEP). They occur as stable spin textures in cert…
Measuring geometric phase without interferometry
T. Malhotra, R. Gutiérrez-Cuevas, J. Hassett +3
A simple non-interferometric approach for probing the geometric phase of a structured Gaussian beam is proposed. Both the Gouy and Pancharatnam-Berry phases can be determined from…
