{"slug":"moire-superconductivity","topic":"moire-superconductivity","title":"Moire & 2D Superconductivity: State of the Field (October 2026)","summary":"Covers superconductivity in magic-angle twisted bilayer graphene, twisted WSe2 bilayers and rhombohedral multilayer graphene, with the open questions on pairing, gap structure and symmetry. The main takeaway is that superconductivity in magic-angle graphene is well documented by transport and tunneling, while its pairing mechanism, its relation to correlated insulators and its chiral or nematic character remain contested. The reports in twisted WSe2 and rhombohedral graphene are more recent, and the rhombohedral result is still a preprint.","version":1,"published_at":"2026-10-30","updated_at":"2026-10-30","stats":{"words":3310,"citations":39,"claims":26,"timeline":17,"benchmarks":10,"open_problems":9,"key_papers":13,"glossary":16},"verification":{"status":"verified","method":"independent AI fact-check against cited sources (evidence pack + web checks); automated citation resolution","claims_checked":26,"issues_fixed":21,"verified_at":"2026-10-30"},"ai_assisted":true,"price":{"usd":"0.20","protocol":"x402","network":"eip155:84532","asset":"USDC"},"url":"https://space-kitty.com/dossiers/moire-superconductivity","preview_url":"https://space-kitty.com/api/v1/dossiers/moire-superconductivity/preview","purchase_url":"https://space-kitty.com/api/v1/dossiers/moire-superconductivity","toc":[{"level":2,"text":"Executive summary","anchor":"executive-summary"},{"level":2,"text":"Background and core concepts","anchor":"background-and-core-concepts"},{"level":2,"text":"Timeline of key milestones","anchor":"timeline-of-key-milestones"},{"level":2,"text":"State of the art","anchor":"state-of-the-art"},{"level":3,"text":"Magic-angle twisted bilayer graphene","anchor":"magic-angle-twisted-bilayer-graphene"},{"level":3,"text":"Multilayer and alternating-twist graphene","anchor":"multilayer-and-alternating-twist-graphene"},{"level":3,"text":"Twisted WSe2 and transition-metal dichalcogenide moiré systems","anchor":"twisted-wse2-and-transition-metal-dichalcogenide-moiré-systems"},{"level":3,"text":"Rhombohedral multilayer graphene without a moiré","anchor":"rhombohedral-multilayer-graphene-without-a-moiré"},{"level":3,"text":"Superfluid stiffness and quantum geometry","anchor":"superfluid-stiffness-and-quantum-geometry"},{"level":3,"text":"Quantitative benchmarks","anchor":"quantitative-benchmarks"},{"level":2,"text":"Open problems and active debates","anchor":"open-problems-and-active-debates"},{"level":2,"text":"Major programs and players","anchor":"major-programs-and-players"},{"level":2,"text":"Outlook: what to watch (next 12-18 months)","anchor":"outlook-what-to-watch-next-12-18-months"},{"level":2,"text":"Key papers","anchor":"key-papers"},{"level":2,"text":"Glossary","anchor":"glossary"}],"sample_claims":["Superconductivity was reported in magic-angle twisted bilayer graphene near a twist angle of about 1.1 degrees, with zero-resistance states up to a critical temperature of 1.7 K at carrier densities of order 10^11 cm^-2.","Superconductivity up to 3 K was reported close to filling factor -2 in magic-angle bilayer graphene, together with further superconducting domes near filling 0 and plus or minus 1 and states with non-zero Chern numbers."],"includes":["markdown","claims","timeline","benchmarks","open_problems","key_papers","glossary","bibliography"],"citation_count":39,"how_to_buy":"GET https://space-kitty.com/api/v1/dossiers/moire-superconductivity with an x402 client ($0.20, USDC on Base Sepolia (testnet))."}
