Pohle et al. (2023) · the lowest unflagged extrapolated energy, an extrapolation, not a bound

Energies as E/N (S.S). Classes are different claims and are not ranked against each other.

The Hamiltonian

H = ∑⟨ij⟩ σi·σj

Nearest-neighbour Heisenberg antiferromagnet, J = 1, written with Pauli matrices.

Stored as a total energy; quoted here as E/N (S.S), which is what the papers report (how the conversion works).

Every published energy

Grouped by what the number is. The exact energy comes first where there is one; in every other group the lowest unflagged energy is its best value, and each row's distance is to that best (rules §6).

Strict variational upper bounds (3)

Energies that a variational state reached (VMC, DMRG and MPS at finite bond dimension, PEPS, NQS, VQE). Each is an upper bound on the ground-state energy.

Extrapolations (2)

Zero-variance or bond-dimension extrapolations. These are not bounds: no ansatz reached the number.

Checked 2026-09-15 · source text of arXiv:2311.11561 read locally (arXiv HTML or pypdf layout text); value copied from the harvested cell and the text, no LLM transcription of numbers; single reading

Main text: 'For Ns=432, they are E0/Ns=−0.4924(2) and E0/Ns=−0.4923(2), respectively' (max. flip. and random initial states). | Paper writes H=J∑S_i·S_j with J=1 (S=1/2 operators, S·S convention, not Pauli); the paper's own isolated-tetrahedron limit value -0.37475(1) matches the exact S·S single-tetrahedron result -3/8=-0.375 per site, confirming no Pauli conversion; magnitude matches catalog's pyrochlore best_per_site scale (~-0.49) directly since the paper already reports E/Ns.
