A skyrmion fluid and bimeron glass emerging from competition with a chiral spin liquid

Abstract : Skyrmions are of interest both from a fundamental and technological point of view, due to their potential to act as information carriers. One great challenge concerns their manipulation and control, especially at higher temperatures. Here we combine skyrmion physics with another aspects of modern condensed matter: spin liquids. Using the high entropy and broken symmetry of a chiral spin liquid, we design a theoretical model to control the density of well defined skyrmions with temperature, all the way from a diluted gas to a dense liquid and a crystallised solid. At high field, the skyrmion fluid forms an original bimeron glass with high degeneracy and out-of-equilibrium dynamics, reminiscent of co-polymer physics and chain models in statistical mechanics. Our approach illustrates how spin-liquid properties can be used for the design of tailored models, and further connects skyrmions to phenomena beyond condensed matter.
