A new research paper published on arXiv details a topological obstruction that affects pure foundation neural quantum states. The study demonstrates that for gapped Hamiltonians with non-trivial ground-state bundles, continuous normalized state-vector models will have zero fidelity with the ground state at certain parameter values. This obstruction can lead to energy estimates that are at least one spectral gap away from the true ground state energy. The research suggests that operator-valued models can circumvent these issues and preserve topological information, indicating a potential structural necessity for future foundation neural quantum state representations.
