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 …

In this review recent investigations are summarized of many-body quantum systems with
long-range interactions, which are currently realized in Rydberg atom arrays, dipolar …

Dipolar Bose-Einstein condensates represent a powerful platform for the exploration of
quantum many-body phenomena arising from long-range interactions. A series of recent …

Supersolids are states of matter that spontaneously break two continuous symmetries:
translational invariance owing to the appearance of a crystal structure and phase invariance …

Can a gas behave like a crystal? Supersolidity is an intriguing and challenging state of
matter that combines key features of superfluids and crystals. Predicted a long time ago, its …

Pattern formation is a ubiquitous phenomenon observed in nonlinear and out-of-equilibrium
systems. In equilibrium, quantum ferrofluids formed from ultracold atoms were recently …

Raising the temperature of a material enhances the thermal motion of particles. Such an
increase in thermal energy commonly leads to the melting of a solid into a fluid and …

At zero temperature, a Galilean-invariant Bose fluid is expected to be fully superfluid. Here
we investigate theoretically and experimentally the quenching of the superfluid density of a …

A new class of superfluids and superconductors with spatially periodic modulation of the
superfluid density is arising,,,,,,,,,,–. It might be related to the supersolid phase of matter, in …

We numerically study the many-body physics of molecular Bose-Einstein condensates with
strong dipole-dipole interactions. We observe the formation of self-bound droplets, and …
