The mystery of quantum phenomena inside materials—such as superconductivity, where electric current flows without energy loss—lies in when electrons move together and when they break apart. KAIST researchers have succeeded in directly observing the moments when electrons form and dissolve ordered patterns.
Research teams led by Professors Yongsoo Yang, SungBin Lee, Heejun Yang, and Yeongkwan Kim of the Department of Physics, in an international collaboration with Stanford University, have become the first in the world to spatially visualize the formation and disappearance of charge density waves (CDWs) inside quantum materials.
The research is published in Physical Review Letters.
