What an Electron Really Looks Like

Measuring the Electron QGT in Kagome Solids Quantum Visualization Breakthrough: International Teams Unveil Electron's Geometry for First Time In a groundbreaking achievement that marks a significant leap forward in quantum physics, an international collaboration led by MIT researchers has successfully measured the geometric "shape" of electrons in solid materials for the first time. This discovery, published in the November 25, 2024 issue of Nature Physics, has opened up entirely new avenues for understanding and manipulating quantum properties of materials that were previously inaccessible to experimental observation. From Theory to Observation While scientists have long been able to measure the energies and velocities of electrons in crystalline materials, their quantum geometry—how electrons are distributed and behave in space as they move through solids—remained theoretical until now. Using highly specialized techniques, the MIT team successfully measured the Qua...
