WebIn the third story, which is the focus of this talk, we prove limitations of a broad class of toy models known as commuting projector Hamiltonians. These models, which include the celebrated toric code model, have been powerful tools for studying interacting topological phases of matter. WebAs shown by, e.g. Dirac in Lectures on Quantum Mechanics, any infinitesimal generator of a symmetry commutes with the Hamiltonian, which itself is the generator of time-translations, i.e. of the dynamics. Typical examples of an Hamiltonian that commutes with P is the free particle, or more generally any admissible function of P alone.
WebAbstract. We introduce a family of commuting-projector Hamiltonians whose degrees of freedom involve Z 3 parafermion zero modes residing in a parent fractional-quantum-Hall fluid. The two simplest models in this family emerge from dressing Ising-paramagnet and toric-code spin models with parafermions; we study their edge properties, anyonic …
