Magnon propagation in an antiferromagnet is revealed in these snapshots of spatially resolved transient reflectance, obtained using pairs of laser pulses. Berkeley Lab scientists have taken the first atomic-resolution images and demonstrated electrical control of a chiral interface state. Members of the team that conducted the research in the Lab. An illustration of a glowing orb of light near a shadowed forest floor, with small leaves illuminated by the orb Person with long, brown hair standing in front of scientific instrumentation. Digital illustration with a dark background featuring five quantum-related scenes. This electron microscopy-derived composite image shows excitons in green. The moiré unit cell outlined in the lower right of the exciton map is about 8 nanometers in size. Graphic illustration depicting three scenes surrounding a spinning microchip. Four scientists converse with each other in a lab. ghost particles quantum gif magnet
