Physicists realize fractionalization without a magnetic field
Wannier states and schematic phase diagram. (a) Wannier states and a typical moiré pattern. The yellow and green blobs schematically represent the shape of Wannier orbitals on the BA and AB sublattices, respectively. (b) Schematic representation of the six-phase registry of AB-BA sites. The vertices of the triangle correspond to the three charge lobes. (c) Proposed phase diagram for the model in Eq. (3). Black arrows in the brick wall phase represent SU(4) spin-valley ferromagnetism. Credit: Physical Review Letters…
