Rattled Atoms Mimic High-temperature Superconductivity
An experiment at SLAC provided the first fleeting glimpse of the atomic structure of a material as it entered a state resembling room-temperature superconductivity – a long-sought phenomenon in which materials might conduct electricity with 100 percent efficiency under everyday conditions.
Image - In a high-temperature superconducting material known as YBCO, light from a laser causes oxygen atoms to vibrate between layers of copper oxide in a way that favors superconductivity.
