Ultrafast imaging reveals existence of 'polarons'

Many people picture electrical conductivity as the flow of charged particles (mainly electrons) without really thinking about the atomic structure of the material through which those charges are moving. But scientists who study "strongly correlated electron" materials such as high-temperature superconductors and those with strong responses to magnetism know that picture is far too simplistic. They know that the atoms play a crucial role in determining a material's properties.
