AWhat changed
Haller and colleagues used confined cesium atoms to move a one-dimensional gas from strong repulsion into an attractive regime. Collective oscillations and loss measurements supported a metastable, highly excited gas state rather than immediate collapse into the clustered ground state.
Scientific scope
Haller and colleagues used confined cesium atoms to move a one-dimensional gas from strong repulsion into an attractive regime. Collective oscillations and loss measurements supported a metastable, highly excited gas state rather than immediate collapse into the clustered ground state. The interpretation depends on the one-dimensional trapping and interaction model. Loss and heating depend on experimental conditions, and the measured collective-mode maximum was not perfectly reproduced by the compared theory. The 2009 journal result and the later 2010 author preprint are the same experiment.

The linked original works support the scoped statement and contribution attribution. WRS has not independently replayed experiments or reconstructed a full mathematical proof.
