A New "Quasi-1D" State of Matter Could Be Hiding Inside Ice Giant Planets

Despite outward appearances, the internal workings of ice giants like Uranus and Neptune are extremely chaotic. Pressures millions of times greater than Earth’s sea level combine with temperatures in the thousands of degrees to make some pretty weird materials. Now, a new paper from researchers at the Carnegie Institution, published in Nature Communications, describes a completely new state of matter that might exist in these extreme environments - a “quasi-1D superionic” phase.
