Researchers confirmed the existence of electronic waves that are frozen at a transition temperature of 125 kelvins and start “dancing together” in a collective oscillating motion as the temperature is lowered. In this illustration, a red laser beam triggers the dance of the newly discovered electronic waves in magnetite.

Dancing electrons solve a longstanding puzzle in the oldest magnetic material

Physicists use extreme infrared laser pulses to reveal frozen electron waves in magnetite.

Beams of circularly polarized light (shown as blue spirals) can have two different mirror-image orientations, as shown here. When these beams strike a sheet of titanium diselenide (shown as a lattice of blue and silver balls), the electrons (aqua dots) in the material take on the handedness of the light's polarization.

Researchers found that strontium cobalt oxide (SCO) naturally occurs in an atomic configuration called brownmillerite (center), but when oxygen ions are added to it (right), it becomes more orderly and more heat conductive, and when hydrogen ions are added (left) it becomes less orderly and less heat conductive.

A material’s insulating properties can be tuned at will

Most materials have a fixed ability to conduct heat, but applying voltage to this thin film changes its thermal properties drastically.
