APR: Plasmonic meron lattice

By ultrafast time-resolved PEEM macroscopic imaging, we record a lattice of topological plasmonic spin textures resembling a lattice of magnetic meron quasiparticles in a nano-patterned metallic square coupling structure. The robustness of the spin angular momentum texture over the excitation pulse duration is demonstrated by extracting deep subwavelength resolution images of linear polarization singularity distributions that define the meron domain boundaries.
