Three-dimensional (3D) gapped topological phases with fractional excitations are divided into two subclasses: one has topological order with point-like and loop-like excitations fully mobile in the 3D space. and the other has fracton order with point-like excitations constrained in lower-dimensional subspaces. These exotic phases are often studied by exactly solvable Hamiltonians made... https://www.diegojavierfares.com/discount-Los-Angeles-Rams-NFL-Womens-Bottom-Line-Crop-Top-p11321-best-save/
