Particle-like topologies in light
Danica Sugic, Ramon Droop, Eileen Otte +5
Three-dimensional (3D) topological states resemble truly localised, particle-like objects in physical space. Among the richest such structures are 3D skyrmions and hopfions that re…
Transverse Shifts and Time Delays of Spatiotemporal Vortex Pulses Reflected and Refracted at a Planar Interface
Maxim Mazanov, Danica Sugic, Miguel A. Alonso +2
Transverse (Hall-effect) and Goos--Hänchen shifts of light beams reflected/refracted at planar interfaces are important wave phenomena, which can be significantly modified and enha…
Polarization singularities and Möbius strips in sound and water-surface waves
K. Y. Bliokh, M. A. Alonso, D. Sugic +3
We show that polarization singularities, generic for any complex vector field but so far mostly studied for electromagnetic fields, appear naturally in inhomogeneous yet monochroma…
Knotted Polarizations and Spin in 3D Polychromatic Waves
Danica Sugic, Mark R. Dennis, Franco Nori +1
We consider complex 3D polarizations in the interference of several vector wave fields with different commensurable frequencies and polarizations. We show that the resulting polari…
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…
