Superconductivity breakthrough: First direct visualization of a zero-field torque density wave
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 electron pairs (yellow spheres) modulates spatially as these electrons move through the crystal. Credit: Brookhaven National Laboratory Tunneling spectroscopy uncovers the clearest evidence that this exotic superconducting state of matter exists … Read more
