Microscopic Insights into the Quarkyonic Hadron--Quark Crossover: Lessons from Ultracold Fermi Gases
The study explores how three-body correlations, called tripling fluctuations, act as a microscopic mechanism linking three-fermion bound states to dense quark matter across a continuous crossover. This mechanism explains phenomena like the baryonic momentum shell and the peaked speed of sound observed in phenomenological models.
