Sylvain Nascimbène (Assoc. Prof./Maître de conférences, LKB BEC/Collège de France, IUF 2022) leads the Dysprosium lab. Research: (1) large-spin dysprosium Bose-Einstein condensates for quantum simulation of exotic magnetic phases; (2) quantum metrology with entangled spin states; (3) realisation of topological matter (2025: parity anomaly in 2D); also theory on topological quantum simulation (with Nathan Goldman). Strong connection to quantum sensing via entanglement-enhanced metrology.
