Superconductivity
Physicists have uncovered a subtle magnetic order within the pseudogap phase of quantum materials, potentially explaining the path to superconductivity. Using an ultracold quantum simulator, researchers observed persistent magnetic patterns that align with the pseudogap's formation temperature. This finding could advance the development of high-temperature superconductors for energy-efficient technologies.

Scientists at the Max Planck Institute in Mainz have directly measured the superconducting gap in hydrogen sulfide, a key step toward high-temperature superconductors. Using a novel tunneling technique under extreme pressures, they confirmed electron-phonon interactions drive the phenomenon. This breakthrough builds on discoveries from 2015 and advances the quest for room-temperature superconductivity.
