To explore what happens when electrical resistance develops in unconventional metals, researchers led by Princeton University physicists sent a density wave through a gas of ultracold atoms (top left). The researchers observed the dissipation of the density wave over time, which is analogous to what happens in metals when resistance slows the flow of electricity. They found that the atoms exhibited behaviors of so-called “bad” and “strange” metals, findings that may help researchers understand high-temperature superconductivity. The bottom row shows the same experiment using a finer ripple. Photo courtesy of the researchers
