Twisted WSe2 Reveals New Insights into Moiré Superconductivity

4/2/2026

Summary

Story summary

Recent studies on twisted bilayer WSe2 expand moiré superconductivity beyond twisted graphene.
Researchers examined twist angles of 3.65° and 5.0°, finding distinct superconducting phase diagrams.
The diagrams evolve with angle, showing a smooth transition tied to a Fermi surface reconstruction, likely with antiferromagnetic ordering.
The results imply interconnected superconducting states across angles and show twisted transition metal dichalcogenides as a platform to study correlated phases as interactions vary.
