Since the achievement of quantum degeneracy in gases of chromium atoms in 2004, the
experimental investigation of ultracold gases made of highly magnetic atoms has …

Quantum fluctuations can stabilize Bose–Einstein condensates (BEC) against the mean-
field collapse. Stabilization of the condensate has been observed in quantum degenerate …

By combining theory and experiments, we demonstrate that dipolar quantum gases of both
Er 166 and Dy 164 support a state with supersolid properties, where a spontaneous density …

The competition of dipole-dipole and contact interactions leads to exciting new physics in
dipolar gases, well illustrated by the recent observation of quantum droplets and rotons in …

Quantum droplets are small clusters of atoms self-bound by the balance of attractive and
repulsive forces. Here, we report on the observation of droplets solely stabilized by contact …

Self-bound quantum droplets are a newly discovered phase in the context of ultracold
atoms. In this Letter, we report their experimental realization following the original proposal …

We study theoretically and experimentally the emergence of supersolid properties in a
dipolar Bose-Einstein condensate. The theory reveals a ground state phase diagram with …

We report on the formation of heteronuclear quantum droplets in an attractive bosonic
mixture of K 41 and Rb 87. We observe long-lived self-bound states, both in free space and …

This brief review summarizes recent theoretical and experimental results which predict and
establish the existence of quantum droplets (QDs), ie, robust two-and three-dimensional (2D …

We study the spectrum of elementary excitations of a dipolar Bose gas in a three-
dimensional anisotropic trap across the superfluid-supersolid phase transition. Theoretically …
