A number of possible pulsar radio emission mechanisms are based on streaming instabilities in relativistically hot electron-positron pair plasmas. At saturation the unstable waves can form, principle, stable solitary which could emit observed intense signals. We searched for proper plasma parameters would lead to formation solitons, investigated their properties and dynamics as well resulting o...

Abstract Various properties and potential technological applications of magnetic skyrmions have stimulated a flourishing interest in topological spin textures. Among them, biskyrmions with rare charge two are observed but their existence is still under debate. In this work, we present the formation biskyrmion bubbles mediated by emergent monopoles via micromagnetic simulations. We find that tri...
