Paper selection and deep-read: identify a recent 2025-2026 paper on Kitaev candidate materials (e.g., α-RuCl3, Na3Co2SbO6, CrI3, or other honeycomb-lattice quantum spin liquid candidates). Read the paper closely, extract 3-6 specific compounds with crystallographic data, and dedup potential author contacts against CRM dataset 019ee292. Done: a specific paper is selected with author names, 3-6 compounds listed, and CRM checked for existing contacts.

Paper Selection: Li et al. (2026) — Kitaev-derived spin liquid in Na₂Co₂TeO₆ Paper: Li, H., Zhou, X.-G., Su, G. & Li, W. "Kitaev-derived spin liquid in the frustrated quantum magnet Na₂Co₂TeO₆." npj Quantum Materials (2026). Part of the "New Horizons in Kitaev Materials" collection. arXiv: 2509.08821 DOI: 10.1038/s41535-026-00903-6 Published: 29 May 2026 Why this paper This paper establishes an effective K-J-Γ-Γ′ model with a dominant antiferromagnetic Kitaev interaction for Na₂Co₂TeO₆, using high-precision tensor-network calculations. It reveals a gapless quantum spin liquid phase under intermediate magnetic fields. It's the first rigorous theoretical demonstration that a cobalt honeycomb material can host a proximate Kitaev QSL, moving beyond the α-RuCl₃ paradigm.

CIF generation and route execution: generate CIFs for the 3-6 extracted Kitaev candidate compounds using ICSD-anchored or ASE-built structures. Run each through Orb v3 relaxation with P1 collapse check, then run applicable prediction routes (MP hull energy, ALIGNN formation energy/properties, CHGNet moments where magnetic). Record all route execution IDs. Done: CIFs created and all route executions completed with results captured, P1 collapse status noted for each compound.

The model slug "jarvis-mf" was rejected by the ALIGNN service. This needs investigation of valid model slugs. Key Finding P1 symmetry collapse extends to Kitaev cobaltate honeycombs. CrI₃ (binary halide) is the only compound that preserves its space group under Orb v3, suggesting the collapse is driven by structural complexity rather than honeycomb topology.

Testing Kitaev QSL candidates through Ouro routes: Na₂Co₂TeO₆ and the honeycomb family under Orb v3
Orb v3 relaxation and convex hull analysis of 6 Kitaev quantum spin liquid candidate compounds from Li et al. (2026), npj Quantum Materials.

Retrospective

The previous mega-quest (019f18d7) grew to 73 items across 14 outreach cycles and proved that a single quest cannot scale to that many research groups without becoming unwieldy. approved its wind-down with clear direction: one quest per research group, multiple quests open simultaneously. The follow-up quest (019f42b4) demonstrated that a 4-item scoped quest is far more manageable — 2 items done in one day, 2 waiting on external timing (follow-up dates, author contact info). This plan follows the same compact pattern.

Focus: Kitaev Quantum Spin Liquid Candidates

Cycles 1-15 covered hydride superconductors, 2D magnetism, thermoelectrics, solid-state batteries, ML potentials, nickelate superconductors, MnBi₂Te₄, altermagnetism, kagome metals, perovskite photovoltaics, dirhenates, NASICON cathodes, spinel oxide electrocatalysts, and magnetic topological materials. Kitaev quantum spin liquids are a major gap — they sit at the intersection of #physics and #superconductors, are intensely active in 2025-2026, and involve crystalline honeycomb-lattice compounds that Ouro's existing routes (CIF generation, Orb v3 relaxation, MP hull, ALIGNN/CHGNet property prediction) can analyze directly.

The pipeline follows the established content-driven outreach pattern: deep-read a recent paper, extract compounds, generate CIFs, run prediction routes, publish an analysis post, then use that post as the personalized hook in a researcher email. The whole cycle is one research group, one quest, four sessions.
