Characterizing $S=3/2$ AKLT Hamiltonian with Scanning Tunneling Spectroscopy

M. Ferri-Cortés, J. C. G. Henriques, J. Fernández-Rossier

The AKLT Hamiltonian is a particular instance of a general class of model Hamiltonians defined in lattices with coordination $z$ where each site hosts a spins $S=z/2$, interacting…
