Here, we demonstrate continuous accumulation of sub-Doppler-cooled atoms in a shallow intracavity dipole trap, realizing this regime. The key ingredient is a light-shift manipulation that creates spatially varying cooling parameters, enabling efficient capture and accumulation of atoms within a cavity mode. Demonstrated with rubidium atoms, a continuous flux from a source cell is funneled through the magneto-optical trap into the cavity mode, where the atoms are cooled and maintained below 10µK in steady state without time-sequenced operation. We characterize the resulting continuously maintained ensemble of millions of atoms and its collective coupling to the cavity field, establishing a route toward continuously operated cavity-QED systems and long-duration atomic and hybrid quantum sensors."}],"status":"public","project":[{"_id":"bdb2a702-d553-11ed-ba76-f12e3e5a3bc6","name":"A quantum hybrid of atoms and milligram-scale pendulums: towards gravitational quantum mechanics","grant_number":"101087907"}],"intvolume":"       114","PlanS_conform":"1","corr_author":"1"}
