The first discovery of unusual chiral quantum states in topological materials provides key clues for the future development of quantum technology

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.
