Click lattice sites to create/annihilate fracton excitations
X-Cube fracton topological order hosts exotic quasi-particles with strictly restricted mobility.
• Fractons: completely immobile isolated excitations — cannot move alone.
• Lineons: bound pairs that move only along a single axis (1D mobility).
• Planons: bound quadruplets that move only within a 2D plane.
The Hamiltonian H = −A∑vAv − B∑cBc enforces these constraints via vertex and cube operators with Z₂ gauge structure.
