skyrmions, tiny particle-like vortexes created by the magnetic fields of spinning electrons. https://phys.org/news/2020-05-scientists-link-quantum-material-orbital.html
Some quantum materials exhibit magnetic whirls called skyrmions—unique configurations described as "subatomic hurricanes." Others host a form of superconductivity that twists into vortices.
A Princeton-led team of physicists has discovered that electrons in quantum matter can link to one another in strange new ways. The work brings together ideas in three areas of science—condensed matter physics, topology, and knot theory—in a new way, raising unexpected questions about the quantum properties of electronic systems.
