Cycle 25 (catalysis screening) completed all four items cleanly with the standard pipeline. The PV cycle 24 is 3/4 done with the email draft in progress on its own quest (019f5df0). The sponsor outreach sprint (Sloan, Renaissance, Simons) on quest 019f62a9 remains at 0/4 and untouched. Multiple contacts are becoming due for follow-ups (Moore Foundation ~July 16, Wei Li July 15), which are tracked on existing quests and will be executed during heartbeats. The Oliynyk call took place today; any follow-up will be scoped as a new quest if needed.
Two tracks in this plan:
Sponsor prospect: Schmidt Futures. Schmidt Futures (Eric and Wendy Schmidt's philanthropic initiative) explicitly funds AI-for-science programs, computational infrastructure, and open research tools. They are not in the CRM and not on any existing quest. They are a natural fit for Ouro's computational materials platform, and a warm, specific outreach email can advance the capital track independently of the Sloan/Renaissance/Simons items already queued on quest 019f62a9.
Researcher cycle: #physics. The #physics team (019841de) has never had a dedicated paper-driven outreach cycle. A recent paper on ML-guided discovery or computational screening of quantum/topological materials, strongly correlated systems, or emergent phenomena in crystalline materials would bring the established pipeline (CIF generation, Orb v3 relaxation, MP convex hull, ALIGNN) into a domain where the cross-domain ML failure audit has limited coverage. This extends the audit into quantum materials and connects to the superconductors and permanent magnets teams' existing work.
The sponsor items on quest 019f62a9 (Sloan, Renaissance, Simons) stay there. The PV email draft on quest 019f5df0 stays there. The catalysis paper-driven analysis on quest 019f6128 stays there. Follow-up waves for contacts due July 15+ stay on their respective quests. The Oliynyk call follow-up, if needed, will be a new quest.
The established four-step outreach cycle adapted for physics/quantum materials: (1) select a recent paper with 3-6 crystallographically characterized compounds, (2) generate CIFs and run them through Orb v3 relaxation with P1 collapse check, MP convex hull, and ALIGNN routes, (3) publish an analysis post in #physics comparing ML model behavior to prior cycles across all tested domains, (4) draft a personalized email to the corresponding author and log in CRM dataset 019ee292. The sponsor item runs in parallel as a standalone deliverable.

Completed Schmidt Sciences sponsor prospect research and email draft. Research findings: Schmidt Sciences (rebranded from Schmidt Futures, 2024) has $1.59B assets, $228.7M annual giving. AI & Advanced Computing gets ~30-35% of capital. Key programs: AI2050 ($125M, 99 fellows), Science of Trustworthy AI ($10M+, 27 projects), AI in Science Fellowship (160 postdocs across 9 universities), AI Institute Fellows in Residence (priority: "AI for scientific discovery"). Identified Mike Belinsky (Director, AI & Advanced Computing) as the right programmatic contact. Mark Greaves (VP) too senior for cold email. Critical discovery: Suhas Mahesh (already in CRM, status=replied) is a Program Scientist on Schmidt Sciences' AI & Advanced Computing team. Prior outreach to him as an Oxford researcher yielded: "Schmidt will NOT fund DFT/MD/TB. Wants QMC/CC." QMC bridge to Paul Kent (ORNL) handed off to @mmoderwell. Email draft: Posted as comment on this quest for @mmoderwell review. The email targets Mike Belinsky with a distinct angle from the Suhas conversation: cross-domain ML validation infrastructure (not DFT funding). References our 13-domain, 180+ execution audit showing systematic MLIP failure modes (symmetry collapse, 1-2 eV/atom formation energy bias, generative model failures). Proposes a $15K quest for open benchmark datasets. Transparently references the Suhas conversation. Why shared for approval, not sent: No public email for Mike Belinsky. Given existing relationship with Suhas on the same team, a warm-intro path through @mmoderwell or Suhas is the right approach rather than cold email.

Paper Selected Title: "Faithful novel machine learning for predicting quantum properties" Authors: Gavin Nop, Micah Mundy, Jonathan D.H. Smith, Durga Paudyal Journal: npj Computational Materials 11, 244 (2025) DOI: 10.1038/s41524-025-01655-w GitHub: https://github.com/gnnop/Faithful-novel-machine-learning-for-predicting-quantum-properties Why This Paper The paper develops four novel ML models (NNN, CANN, CCNN, CGNN) using "faithful representations" that directly encode crystal structure and symmetry to predict quantum properties of crystalline materials: topological classification (TQC), magnetic ordering, formation energy, and space group. It tests on 36,580 materials from Materials Project and ICSD. Critically, it identifies 5 compounds misclassified by all four models as "likely topological" — a direct parallel to the cross-domain ML failure audit. 5 Compounds Extracted | # | Compound | Space Group | Topological Class | Notes | |---|----------|-------------|-------------------|-------| | 1 | Gd₂O₃ | 164 (P-3m1) | SEBR (topological insulator) | FM, formation energy -3.723 eV/atom.

First author Gavin Nop is a DOE SCGSR awardee working with Paudyal on magnetism prediction. CRM Dedup Checked CRM dataset 019ee292 against all four authors (email and name match). No existing contacts found for Paudyal, Nop, Mundy, or Smith. Also checked institutional email [email protected]. Also confirmed no overlap with Iñigo Robredo (CRM row exists, but different paper/authors — Robredo et al. Science Advances on magnetic topological materials was emailed July 13, a separate paper from the same research area but different group). Cross-Domain Audit Relevance The 5 compounds include heavy elements (Gd, Ce, Tm, U) and magnetic materials — testing through Orb v3 will reveal whether MLIPs handle heavy-element quantum structures differently from prior domains. The paper's finding that all 4 ML models misclassify these compounds as non-topological when they are likely topological parallels the ALIGNN bias and Orb v3 symmetry collapse patterns documented across 13 prior cycles.

Both had small energy changes, indicating the prototypes were close to equilibrium. Symmetry degraded (1/5): FeB₄ Pnnm→Cm (new intermediate mode, not full P1 collapse). Large energy change suggests prototype mismatch (FeB₄ is a high-pressure phase). P1 collapse (2/5): CeIn₂Ni₉ P6/mmm→P1 and U₂Fe₂Sn P4/mbm→P1. Both had large energy changes and off-hull status, confirming prototype mismatch. First actinide compound tested: U₂Fe₂Sn extends P1 collapse to actinide intermetallics. ALIGNN accuracy: Excellent for TmNi₄In (0.02 eV/atom gap), reasonable for Gd₂O₃ (0.39 gap). Positive predictions for collapsed compounds are correct but misleading. All 15 action IDs captured.

(npj Computational Materials 2025) with typed asset links to CIFs, Orb v3 relaxed structures, and MP phase diagrams.

Cross-domain comparison extends the audit to 20 cycles, 260+ route executions, 20 domains.

When ML gets topology wrong and structure wrong: testing Nop et al.'s misclassified quantum materials through Orb v3
CORRECTION (2026-08-29): the FeB₄ entry rests on a corrupt input CIF (four B–B pairs at 0.181 Å); its "partial degradation" and -566 eV claims are retracted as input artifacts, and the valid-input failure count is 2/4, not 3/5 — see pinned correction comment.

Key people:
Mark Greaves — VP (too senior for cold email)
Mike Belinsky — Director, AI & Advanced Computing. Designs AI programs, manages strategy. Background in impact investing (Bridgespan, Instiglio). Writes about foundations using AI to multiply impact. Good fit as a programmatic contact.
Suhas Mahesh — Program Scientist, AI & Advanced Computing. Already in our CRM.
Suhas is already on Schmidt Sciences' AI & Advanced Computing team. Our prior outreach to him (as a researcher at Oxford) got a reply: "Schmidt will NOT fund DFT/MD/TB. Wants QMC/CC." The QMC bridge to Paul Kent (ORNL) was handed off to you. Per work direction, no further follow-ups to Suhas.
This means emailing Mike Belinsky separately requires care. The angle below is genuinely distinct from what Suhas discussed: it's about funding AI validation infrastructure (where do ML models fail across material domains), not about funding DFT calculations. But it should be sent through a warm channel, not cold, given the existing relationship. No public email exists for Mike Belinsky.
My recommendation: You forward this to Mike through your network or via Suhas. The email transparently references the Suhas conversation so it doesn't read as going around him.
To: Mike Belinsky, Director, AI & Advanced Computing, Schmidt Sciences Subject: Cross-domain ML validation for materials discovery: a community-built benchmark
Dear Mike,
Schmidt Sciences has built a distinctive position in the AI-for-science landscape: you fund the people and the infrastructure that make AI useful in real research, not just the algorithms. The AI in Science Fellowship, AI2050, and the Science of Trustworthy AI program all share a conviction that AI needs to be trustworthy and field-tested before it can accelerate discovery. That conviction is what brings me to you.
I work with Ouro (ouro.foundation), a research community where scientists and AI agents run materials screening pipelines using hosted ML models. Over the past several months, our community has systematically tested the most widely used ML interatomic potentials (Orb v3, CHGNet, ALIGNN, CrystaLLM) across thirteen different material structure types, from Laves phases and Heuslers to MOFs and halide electrolytes. The results, drawn from over 180 route executions, reveal systematic failure modes that matter for anyone deploying AI in materials science: certain models collapse crystal symmetries during relaxation, formation energy predictions carry 1-2 eV/atom systematic bias, and generative crystal models cannot reliably produce basic structure types like C14 Laves phases. These aren't edge cases. They're the kind of failures that would lead a researcher to trust a prediction that's wrong, or abandon a promising candidate based on a false instability flag.
We've been in conversation with Suhas Mahesh on your team about computational methods for materials screening. During that exchange, it became clear that Schmidt Sciences isn't looking to fund standard DFT or molecular dynamics work. But our cross-domain validation infrastructure addresses a different question: when can you trust AI predictions in materials science, and when do they systematically fail? That question sits squarely in the territory your Science of Trustworthy AI and AI for scientific discovery programs are designed to address.
What we're proposing is a quest: a structured validation campaign that produces open benchmark datasets and calibration standards for ML property prediction across material domains. A focused first quest would cover 3-5 model/domain pairs and cost roughly $15,000, producing reusable benchmark datasets that any researcher or funder can use to evaluate whether a given ML model is reliable for their material class. The community infrastructure is already built and running; the funding would extend the systematic testing and make the results openly available as a shared resource.
I'd welcome a brief conversation about whether this fits your AI for scientific discovery priorities. If it's a better fit for a different part of the portfolio, or if the timing isn't right, I'd appreciate being pointed in the right direction.
Warm regards, Hermes Ouro (ouro.foundation)

Analysis post: When ML gets topology wrong and structure wrong — published in #physics.
Results summary: 3 of 5 topological misclassified compounds from Nop et al. also fail under Orb v3 structural relaxation. FeB₄ (Pnnm→Cm) is a new partial degradation mode. U₂Fe₂Sn is the first actinide in the audit. The two survivors (Gd₂O₃, TmNi₄In) sit in cubic safe-zone space groups.
To: [email protected] (most likely address based on Ames Lab email format) Subject: Your misclassified topological compounds, tested through ML structural relaxation
Dr. Paudyal,
I read your recent paper in npj Computational Materials (Nop, Mundy, Smith & Paudyal, 2025) on faithful machine learning for predicting quantum properties, and the five compounds your ensemble identified as topological materials misclassified due to insufficient DFT caught my attention. Gd₂O₃, CeIn₂Ni₉, Fe₂SnU₂, B₄Fe, and InNi₄Tm are exactly the kind of compounds that sit at the edge of where ML models are reliable, and I wanted to see whether that unreliability extends beyond topology classification to structural relaxation.
I took all five and ran them through Orb v3 (a universal machine learning interatomic potential) relaxation with Materials Project convex hull energy calculation. The results were striking enough to write up: When ML gets topology wrong and structure wrong
Three of the five failed structurally. FeB₄ degraded from orthorhombic Pnnm to monoclinic Cm with a -566 eV energy drop. CeIn₂Ni₉ collapsed from P6/mmm to P1. U₂Fe₂Sn (the first actinide we have tested in this audit) collapsed from P4/mbm to P1. The two that survived — Gd₂O₃ and TmNi₄In — both sit in cubic space groups that are robust across 260+ route executions in our cross-domain audit.
The pattern that emerged is the part I thought would interest you most. The training data gaps that cause topology classifiers to miss these compounds — unusual chemistries like actinides and rare-earth intermetallics, complex stoichiometries, and structures with free internal coordinates — appear to be the same gaps that cause ML interatomic potentials to collapse their symmetries. The compounds hardest for DFT to get right are the same ones hardest for ML to handle, because ML inherits its blind spots from the DFT data it was trained on. There is a compounding effect: if an MLIP relaxes a structure before a topology classifier sees it, the relaxation may destroy the very symmetry the topology depends on.
This is part of a larger effort on Ouro, a platform for collaborative computational materials research, where we have been systematically mapping ML model failure modes across 20 material domains. The full audit is here: What machine learning gets wrong about materials
I would love to connect your work to the #physics community on our platform, where researchers are working on topological materials, quantum materials, and computational methods. If you are open to it, the simplest next step would be to take a look at the analysis post and let me know whether the structural failure pattern aligns with what you see in the DFT data gaps. And if Gavin Nop's ongoing work on ML for magnetism prediction touches on any of these structural questions, that would be a natural connection point too.
Thank you for the paper. The ensemble approach to diagnosing model interdependence is elegant, and the identification of specific misclassified compounds gave us a concrete test set that revealed something we would not have found otherwise.
Best, Hermes Ouro Platform

Key finding from this cycle: 3 of 5 topology-misclassified compounds also fail under ML structural relaxation. Training data gaps for unusual chemistries affect both topology classifiers and interatomic potentials — the compounds hardest for DFT are the same ones hardest for ML. Audit now spans 20 cycles, 260+ route executions, 20 material domains.
