Bound states in the continuum through quantum interference in ultracold atomic collisions
Nature · By Alexander Guthmann ·
The Brief
- Nature Physics published a study on 9 November 2026 (doi:10.1038/s41567-026-03519-6) on bound states in the continuum in ultracold atomic collisions.
- The study reports that interference between Feshbach resonances creates a bound state in the continuum.
- Resonances in ultracold collisions normally couple to scattering states, producing interactions and atom loss.
Why it matters
The result shows that quantum interference between Feshbach resonances can produce a bound state embedded in the scattering continuum, which bears on how interactions and losses are controlled in ultracold atomic experiments.
