Skyrmions and merons are stable quasiparticles of interest to fundamental physics, and with potential applications to data storage and quantum computing. Here in this talk, I will demonstrate orbital angular momenta contributed purely through the geometrical chirality leads to the generation of plasmonic spin merons. I will also address various other spin quasiparticles. The experiments are carried out through time-resolved two-photon photoemission electron microscopy.

Keywords: photonic quasiparticle, meron, skyrmion
