First direct Visualization of a Zero-field Pair Density Wave

Illustration of the superconducting material Eu-1144
In this illustration of the superconducting material Eu-1144, the blue and magenta wave shown above the crystal lattice represents how the energy level of the electron pairs (yellow spheres) spatially modulates as these electrons move through the crystal.

In the field of superconductivity—the phenomenon in which electrons can flow through a material with essentially zero resistance—the “holy grail” of discovery is a superconductor that can perform under everyday temperatures and pressures. Such a material could revolutionize modern life. But currently, even the “high-temperature” (high-Tc) superconductors that have been discovered must be kept very cold to function—too cold for most applications.

Scientists still have much to learn before room-temperature superconductivity can...
