The Hamiltonian
An impurity model from the upstream set (SB-DMFT-MI-HF). Its Hamiltonian is defined by VarBench rather than here, so it is identified by name rather than restated, and it has no meaningful per-site energy.

Stored as a total energy in the convention of
VarBench; quoted here as
E (total), which is what the papers report
(how the conversion works).
Every published energy
Grouped by what the number is. Ranking happens only inside the first group.
Strict variational upper bounds (1)
The record is the lowest eligible energy in this group, and only this group.
Numerically exact (1)
Exact diagonalization, an exact solution, or sign-problem-free QMC where that is established: the answer, not a claim about it.
