Physicists Create Fractional Fermi Sea Quantum State

Key Details

• The experiment confined atoms to one dimension and drove them through strongly interacting states to produce a highly organised many-body system.
• The resulting state shows forms of hidden quantum order that go beyond the behaviour expected from simpler one-dimensional Fermi systems.
• Such controlled states are useful for quantum simulation, where ultracold atoms are used to study complex quantum behaviour that is difficult to model directly.
