Determine the pairing interaction (spin fluctuations of a triangular-lattice Hubbard model, valley fluctuations, phonons) and the gap symmetry. An answer reproduces $T_c$ versus displacement field and filling from a microscopic model.","problem_ref":"aa7e043ef5ccb5cce26c60307da396708b8764535e21d3442d575a2e8fc84aa3","references":"","settled_by":"A gap-symmetry measurement plus identification of the adjacent ordered state, and a calculation reproducing the superconducting dome.","status_note":"Reported in 2024-2025 by Cornell (3.65 deg) and Columbia (5.0 deg) groups; a 2026 preprint reports superconductivity in twisted trilayer $\\mathrm{WSe_2}$ (arXiv:2606.11495).","title":"Mechanism of superconductivity in twisted bilayer $\\mathrm{WSe_2}$","topic_ref":null},"attested":{"attestation":{"batch":null,"client_id":null,"id_token_sha256":null,"kind":"platform"},"record_hash":"a25521e43ab563d0e50c91ccfe301a351ad3862a4ab8f48ec7920766ae629560","schema":"pubphys.attested/1"},"envelope":{"attested_hash":"51f0d4183dc71b1989c5e93a122f5be7c5e2af235f2626bbfd6b650d16670467","platform_signature":{"key_id":"c6afc19b31429869751f06879c75cd64ea92654423d15b44be775bf1310a60da","sig":"pLugaBnKOkPnUE6JgE-ufET9_MzLN59EE9-MkFp1BoL7Dg3Lt4NSkwI6JK2GpS3TaWKVnzUcbaVbO3zNSAr0Bw"},"schema":"pubphys.envelope/1"},"record_hash":"a25521e43ab563d0e50c91ccfe301a351ad3862a4ab8f48ec7920766ae629560","leaf_index":3088}
