Domain-specific

• AKLT Model
  • The Hamiltonian penalizes the total-spin-2 sector on every neighboring physical-spin pair, so the constructed VBS state is annihilated by each nonnegative local term.
• Matrix Product State
  • It is also distinct from DMRG: DMRG is an optimization procedure whose modern variational state class is MPS.
