Lorenzo Rosso, Leonardo Mazza, Alberto Biella. Eightfold way to dark states in SU(3) cold gases with two-body losses. Phys.Rev.A, 2022, 105, pp.L051302. ⟨10.1103/PhysRevA.105.L051302⟩. ⟨hal-03572985⟩

We study the quantum dynamics of a one-dimensional SU(3)-symmetric system of cold atoms in the presence of two-body losses. We exploit the representation theory of SU(3), the so-called eightfold way, as a scheme to organize the dark states of the dissipative dynamics in terms of generalized Dicke states and show how they are dynamically approached, both in the weakly- and and strongly-interacting and dissipative regimes. Our results are relevant for a wide class of alkaline-earth(-like) gases experiments, paving the way to the dissipative preparation and exploitation of generalized Dicke states.
