feature/SOF-7975 Feature: defect formation energy across charge states and supercell sizes [AI-written] - #366
Conversation
…ergy Charged-defect formation energy needs the pristine supercell's band_gaps for E_VBM and the mu_e range, resolved the same way the total energy already is. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
One job per (supercell size, charge state): the charge is written into the defective-cell SCF as tot_charge, and the k-grid is scaled with the supercell so the k-point density is fixed. Adds the electron-reservoir term the workflow does not carry, q(E_VBM + mu_e), giving formation energy against the electron chemical potential with the stable charge state and the transition levels, and extrapolates the image-charge error away over the sizes in place of an analytical finite-size correction. The pristine total energy and band gap are reused when the material already carries them and computed otherwise, so no notebook has to be run first.

Properties inherit their job's owner, so under an organization the my_account scope could never see what this notebook had just created: section 6.1 rebuilt the reference jobs every run and 7.2 then subscripted None. find_property_for_material takes the account the jobs are created under. Section 7 carried errored jobs into the analysis, where a missing value raised mid-plot or fitted to nan and rendered as a table. Sections 7.2 and 7.3 now read the finished jobs only, as equation_of_state.ipynb already does, and say how many were dropped. Also: the b/L^3 term is fitted only with four or more sizes, three being square; the size fit reports E_f at the VBM so it lands on 7.2's scale; the k-grid rounds instead of flooring [4,4,4] at n=3 to a Gamma-only grid; and the missing-elemental error was not an f-string. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The workflow does not read E_PRISTINE from a material property. It finds the most recent finished job whose name matches "Total Energy" and takes that job's total_energy (shell/fetch_bulk_total_energy). Section 6.1 checked for a property instead, on a different key with no owner notion, so a property that existed without such a job -- public or curated, which cell 6 documents as a supported source -- made it skip the job the workflow needs, and every defect job then failed its assertion. The total-energy check now queries jobs the same way; the band gap stays a property lookup, because section 7.2 reads it as one. The k-grid docstring no longer claims a constant density it cannot hold: the rounded grid bottoms out at Gamma-only, and it is now printed per job. A missing band gap warns and skips 7.2 rather than raising, which had made 7.3 -- which needs no band gap -- unreachable under Run All. eigenvalueValence is optional in the schema and is no longer dereferenced unconditionally. Also: the previous commit's markdown had doubled backslashes in the 7.3 LaTeX; submit_jobs is guarded like the wait beside it; the workflow rename carries a note that the "Total Energy" prefix is load-bearing. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
…what is reused fetch_bulk_total_energy is two queries, not one: the most recent finished job named "Total Energy", then that job's total_energy restricted to the qe: group. Only the first was mirrored, and total_energy.ipynb writes the same workflow name for vasp and nwchem -- so a prior VASP run on the same structure made section 6.1 skip, and the defect jobs then failed the assertion after the SCF. The reuse branch printed nothing identifying what it reused. A reference computed at a different k-grid is the one silent way these numbers go wrong, so it names the job. Two documentation claims were wrong. The k-grid does not hold the density fixed once the divided grid reaches 1, which cell 6 and section 4.2 both still asserted; and PRISTINE_PROPERTY_SOURCE no longer governs the total energy at all, only the band gap -- believing otherwise is what produced the earlier defect.

figure.show() resolves plotly's default renderer, which is "browser" whenever there is no kernel to draw into -- so running these cells outside a notebook pops a tab instead of plotting. render_figure is the helper the corpus already uses for this (analyze_convex_hull.ipynb): IPython.display under Pyodide, the kernel's own renderer otherwise. Verified under a real ipykernel: the cell emits display_data with mime type application/vnd.plotly.v1+json -- the live plotly bundle, so the legend stays clickable and hover labels keep working, in JupyterLite as well.

The Cypress feature points the notebook at a seeded fixture material, which folder-then-Standata could not reach. Restores the three-way lookup the sibling notebook already has, and which the review asked for. Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>

Revert the temporary wheel before merge.
This default changes all Pyodide notebooks to an unreleased development wheel. Restore mat3ra-notebooks-utils after the release includes find_property_for_material. Delete packages/mat3ra_notebooks_utils-2026.9.7.post1.dev7+g881e22dd-py3-none-any.whl in the same change.
The PR objective explicitly requires this reversion before merge.

… reuse k-grid The lower envelope in 7.2 is a comparison between charge states, so plotting a size where one of them failed reports the wrong stable charge. It now picks the largest size that has every value in CHARGES, and skips the section when none does -- skips rather than raises, so 7.3, which needs neither the band gap nor a complete set, still runs under Run All. Reusing a reference computed at another k-grid is the quiet way these numbers go wrong: E_PRISTINE and E_VBM would come from a different sampling than the defective cell they are subtracted from. Section 6.1 now compares the existing job's grid against scf_kgrid_for(scaling) and recomputes on a mismatch. Only an explicit SCF_KGRID can be compared; the KPPRA default adapts per material.

🟡 Minor · Resolve the band-gap property to its source job before checking the k-grid.
other/materials_designer/workflows/defect_formation_energy_charged.ipynb:550-632
🚀 Performance & Scalability | 🟡 Minor | ⚡ Quick winResolve the band-gap property to its source job before checking the k-grid. The k-grid check added in
1ee98efpasses the property-holder returned byfind_property_for_materialtoreference_matches_kgrid, which expectsworkflow.subworkflows. With an explicitSCF_KGRID, the check returnsFalse, so rerunning the notebook recomputes compatible band-gap references instead of reusing them. Preserve the property-holder for band-gap consumption, but resolve its source job for actual k-grid validation. When no explicit k-grid is configured, retain the existing KPPRA behavior.🤖 Prompt for AI Agents

…ional pristine relaxation create_job and find_job_for_material take tags. The notebook tags every job charge:<q>, reuses a pristine reference only from a finished charge:0 job that reported the property (the same lookup the workflow makes), sets the workflow's CHARGE next to tot_charge, and can relax the pristine cell (variable cell) before building the supercells. Co-authored-by: Cursor <cursoragent@cursor.com>
…is never a reference A vc-relax job reports total_energy, and for n = 1 the unrelaxed pristine supercell is the unit cell itself: tagged charge:0, a relaxation was reusable as the pristine reference. Found by name alone now, so find_job_for_material keeps its signature. Co-authored-by: Cursor <cursoragent@cursor.com>

…the first substring match load_material takes an exact name first, else a part of a name only one material has, and names the candidates when several match. The neutral defect notebook uses it and stops when the defective and pristine names resolve to the same structure - the live default (both 'Si') submitted a one-material job that failed in assign-material-id. The charged notebook takes an exact Standata name first, then load_material. Co-authored-by: Cursor <cursoragent@cursor.com>

It created or found them in 6.1, so it passes their ids as the workflow's job filters and sets no tags filter: that would need tagged properties, i.e. the web-app change deployed. Jobs stay tagged by charge; that is the notebook's own reuse key and works on any platform. tmp: standata wheel rebuilt with the job filter - REVERT BEFORE MERGE.

Search for materials. To get an exact one if it matches, or list submatches.
So to distinguish stuff like "Graphene mp-123" and "Graphene mp-123 relaxed"
yet keep the flexibility of using only partial name

Closes SOF-7975. Needs standata#162 and web-app#2977 (properties carry their job's tags; the Cypress cover).
Adds
defect_formation_energy_charged.ipynb. It runs the Defect Formation Energy workflow across charge states and supercell sizes, and draws the two plots from the ATK charged-defects tutorial.defect_formation_energy.ipynbis untouched.What it does
RELAX_PRISTINErelaxes the pristine cell first (Variable-cell Relaxation, or reuses an earlier one), and every supercell is built from the result. The pristine cell is scaled first and the defect placed into each supercell.tot_chargeinpw_scf, and the workflow'sCHARGE. The platform'sdefect_formation_energyis thenE_fat the valence band maximum (VBM), withq·E_VBMincluded by the workflow (standata#162).charge:<q>.charge:0job on that material already reported the property. The notebook then names those jobs to the workflow (REFERENCE_JOB_FILTER), which reads exactly their properties — so no other calculation on the cell can stand in, and nothing depends on properties carrying tags (that path, web-app#2977, is wired for the future).E_f + q·μ_efor0 ≤ μ_e ≤ E_gap, the stable-charge envelope and the transition levels.E_f(L) = E∞ + a/L (+ b/L³)across sizes, in place of an analytical correction. Freysoldt/FNV is out of scope.Library
create_job(..., tags=None)sets the job's tags.load_materialtakes an exact name first, otherwise a part of a name that only one material has, and lists the candidates when several match. It never silently takes the first substring match. Both defect notebooks use it:defect_formation_energy.ipynbalso stops when the defective and pristine names resolve to the same structure. Its live defaults (both"Si") produced a one-material job that failed inassign-material-idwithIndexError;find_total_energy_for_materialis generalised tofind_property_for_material(client, material_id, property_name, source); the old name stays as a delegate. Tests are intest_property_api.py, next to the other module-named tests.Verified
