In the 1980s, the discovery of electron states that fractionalize in the presence of a time-reversal symmetry breaking magnetic field opened up new directions in condensed matter physics. In 2023, evidence has accumulated that a version of these states in which the time-reversal symmetry breaking is spontaneous appears in moiré materials.
