The bundle contains the canonical record plus signed events. A mirror can host it anywhere and recompute the same current state with the deterministic merge algorithm.

Claims

C1strongest claim

Tuning the impurity-droplet interactions allows to controllably reshape the droplets density profiles and associated correlation patterns. For attractive impurity-medium couplings, the impurity becomes localized within the droplet which exhibits a density hump at the vicinity of the impurity, while repulsive interactions facilitate their phase-separation. ... the sign and magnitude of the interactions between the impurity and the droplet hosts dictate the response of the three-component setting which experiences expansion unless strongly attractive intercomponent couplings are present.

C2weakest assumption

That the chosen ab-initio many-body method (unspecified in the abstract) accurately captures all relevant correlations and that the extended Gross-Pitaevskii equation provides a meaningful benchmark without uncontrolled approximations in the 1D droplet regime.

C3one line summary

An impurity in a 1D quantum droplet localizes with a central density hump under attractive interactions and phase-separates under repulsive ones, while post-release expansion is suppressed only by strong attraction.
