We have found the exact groundstate for a large class of antiferromagnetic spin-1 models with nearest-neighbour interactions on a linear chain. All groundstate properties can be calculated. The groundstate is determined as a matrix product of individual site states and has the properties of the Haldane scenario.

Discussion (0). Continue with ORCID to comment.

    hep-th 2024-11 conditional novelty 7.0 of 10

    Matrix product state simulations of real-time scattering in Ising Field Theory reproduce perturbative results near free fermion and E8 limits and support a conjectured crossover in high-energy elastic versus inelastic...

  2. Simultaneous approximation of multiple degenerate states using a single neural network quantum state

    quant-ph 2025-09 conditional novelty 6.0 of 10

    A single shared trunk plus one linear head per state can represent a degenerate eigenspace exactly if the trunk width is at least the combined linear rank of target log-moduli and phases minus one on the common support.
