Fractonization is a method used in certain areas of physics, particularly in quantum many-body systems, to describe fractional excitations. It involves breaking down a system into smaller, non-integer units, or "fractons," which exhibit unique properties such as restricted mobility and entanglement. This approach helps in understanding complex phenomena like topological order and emergent behaviors in condensed matter systems. In practice, fractonization can be achieved through specific Hamiltonians or models that support such fractional excitations.
