Correlated electrons 'tango' in a perovskite oxide at the extreme quantum limit

A team led by the Department of Energy's Oak Ridge National Laboratory has found a rare quantum material in which electrons move in coordinated ways, essentially "dancing." Straining the material creates an electronic band structure that sets the stage for exotic, more tightly correlated behavior—akin to tangoing—among Dirac electrons, which are especially mobile electric charge carriers that may someday enable faster transistors. The results are published in the journal Science Advances.
