:orphan: Starrett--Saumon single-species ion structure ============================================== This benchmark compares Otter with local numerical extractions from :cite:t:`StarrettSaumon2014`, *High Energy Density Physics* **10**, 35--42 (2014), `doi:10.1016/j.hedp.2013.12.001 `__ (PII ``S1574181813001900``). Starrett TF values are open circles; accepted Otter QM and TF calculations are solid blue and dashed orange lines. The directly executable program contains the state definitions, public :class:`~otter.PlasmaWorkflowConfig` calls, strict reliability gates, checksum validation, and plotting: :ref:`sphx_glr_benchmarks_gen_benchmarks_plot_starrett_single_species_2013_2014.py` ``USE_PRECOMPUTED_DATA = True`` loads checksummed current-Otter baselines. Set it to ``False`` to calculate the selected states locally. The script saves both PNG and PDF. Accepted calculations --------------------- All twelve QM/TF calculations pass the electronic, HNC, and independent transform-closure gates with Otter's default 4096-point radial grid. Method ------ The IS-QM path solves the finite-temperature KS average atom; the IS-TF path uses the Thomas--Fermi electronic model. Both feed the same pseudoatom, finite-temperature Lindhard response, Chabrier LFC, and QOZ/HNC workflow described by :cite:t:`StarrettSaumon2014`. Ordinary Fermi--Dirac bound occupations are used. A candidate must pass full and external electronic convergence, the threshold-state check, the nonlinear HNC residual, and the independent Fourier-transform closure check.
