Electrons in a Crystal Found to Exhibit Linked and Knotted Quantum Twists
As physicists delve deeper into the quantum realm, they are discovering an infinitesimally small world composed of a strange and surprising array of links, knots, and winding. Some quantum materials exhibit magnetic whirls called skyrmions — unique configurations described as “subatomic hurricanes.” Others host a form of superconductivity that twists into vortices. Now, in an ...
