Superconductivity, a phenomenon in which electricity flows without resistance, is considered the core of quantum computers and next-generation power technologies. However, the exact states electrons undergo before superconductivity emerges have not yet been fully elucidated.
KAIST researchers have provided experimental clues revealing the hidden order electrons form before superconductivity in a kagome metal, a material closely related to superconducting phenomena. The team confirmed that a loop-like circulating order of electrons (loop-current order) emerges earlier than the periodic clustering of electrons (charge density wave).
The work is published in the journal Nature Physics.
