For the first time, researchers have imaged how pairs of electrons behave in a superconductor. Credit: Lucy Reading-Ikkanda/Simons Foundation For the first time, researchers have directly visualized the quantum behavior that drives superconductivity, a state in which paired electrons allow electricity to flow with zero resistance at very low temperatures. But what they observed came as a surprise. In a study published April 15 in Physical Review Letters , the team captured images of individual
