Abstract: Three-dimensional topological solitons attract a great deal of interest in fields ranging from particle physics to cosmology, but remain experimentally elusive in solid-state magnets. Here we numerically predict magnetic heliknotons, an embodiment of such nonzero-Hopf-index… read more here.

Abstract: This paper uses a spiral cone wavefront to modulate a radially polarized Airy beam. Based on the vector diffraction theory, the focusing and propagation characteristics of a radially polarized spiral cone Airy beam are studied.… read more here.
