On May 13th, the latest issue of Nature Communications published a research result led by Princeton University in the United States: the team used a newly developed scanning photocurrent microscope to directly observe the chiral symmetry breaking phenomenon hidden behind the charge density wave in a Kagome lattice topology material called KV3Sb5 for the first time. This discovery not only answers the long-standing debate about whether topological materials can spontaneously form chiral quantum states, but also provides key clues for the development of future new quantum technologies.
