TL;DR: Experiments with ultracold magnetic atoms reveal liquid-like quantum droplets that are 20 times larger than previously observed droplets as discussed by the authors, which is the largest known quantum droplet size.

TL;DR: In this paper, the authors realize the extended Bose-Hubbard model for an ultracold gas of strongly magnetic erbium atoms in a three-dimensional optical lattice, revealing the anisotropic character of the onsite interaction and hopping dynamics and their influence on the superfluid-to-Mott insulator quantum phase transition.

TL;DR: In this paper, the formation of a macro-droplet state in an ultracold bosonic gas of erbium atoms with strong dipolar interactions was reported, and the authors quantitatively proved that quantum fluctuations stabilize the gas far beyond the instability threshold imposed by mean-field interactions.

TL;DR: The supersolidity phase of matter achieved long-lived hallmarks of supersolidities via two different techniques, setting the stage for future investigations into the phase's behavior.

TL;DR: In this article, it was shown that dipolar quantum gases of both $166$Er and $164$Dy support a state with supersolid properties, where a spontaneous density modulation and a global phase coherence coexist.
