Exact Solutions and Degenerate Properties of Spin Chains with Reducible Hamiltonians
The Jordan–Wigner transformation plays an important role in spin models. However, the non-locality of the transformation implies that a periodic chain of N spins is not mapped to a periodic or an anti-periodic chain of lattice fermions. Since only the N − 1 bond is differ...
