Researchers used a specially designed cavity to strengthen quantum vacuum fluctuations and enhance superconductivity in a thin material. Empty space is not truly empty. Even a vacuum contains restless quantum fluctuations, and researchers have now shown for the first time that these normally subtle effects can be engineered to strengthen superconductivity. The work, led by [...]

A material once thought to be nonmagnetic may reveal a hidden magnetic side when made just a few atomic layers thick. A newly proposed class of magnetism known as altermagnetism could open new possibilities for making computer memory smaller and more efficient. Now, researchers have found evidence that ruthenium dioxide, a quantum material long debated [...]
