Optical topological lattices of Bloch-type skyrmion and meron topologies
文献摘要：
Optical skyrmions,quasiparticles that are characterized by the topologically nontrivial vectorial textures of op-tical parameters such as the electromagnetic field,Stokes parameters,and spin angular momentum,have aroused great attention recently.New dimensions for optical information processing,transfer,and storage have become possible,and developing multiple schemes for manipulating the topological states of skyrmions,thus,is urgent.Here we propose an approach toward achieving dynamic modulation of skyrmions via changing the field sym-metry and adding chirality.We demonstrate that field symmetry governs the skyrmionic transformation between skyrmions and merons,whereas material chirality modulates the twist degree of fields and spins and takes control of the Néel-type-Bloch-type skyrmionic transition.Remarkably,the enantioselective twist of skyrmions and mer-ons results from the longitudinal spin arising from the chirality-induced splitting of the hyperboloid in the mo-mentum space.Our investigation,therefore,acts to enrich the portfolio of optical quasiparticles.The chiral route to topological state transitions will deepen our understanding of light-matter interaction and pave the way for chiral sensing,optical tweezers,and topological phase transitions in quantum matter.
