Three-component Fermi gases: stability and energy dynamics*

Uniform ultracold quantum gases with three (pseudo-)spin components are a promising platform for exploring novel physics, such as exotic “spin-1” superfludity and analogues of QCD. But much remains to be understood about the stability of these systems. Building on our recent observation of anomalous losses in three-component mixtures of ⁶Li [1], we expand our measurements to additional interaction regimes, and we present energy-resolved loss measurements. Seeking to shed light on the microscopic mechanism behind these anomalous losses, we explore the scaling of the loss rate with the average energy of the system.
