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 …

We review the recent developments and the current status in the field of quantum-gas cavity
QED. Since the first experimental demonstration of atomic self-ordering in a system …

Supersolid states simultaneously feature properties typically associated with a solid and with
a superfluid. Like a solid, they possess crystalline order, manifesting as a periodic …

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 …

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 …

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

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 …

Ferrofluids exhibit unusual hydrodynamic effects owing to the magnetic nature of their
constituents. As magnetization increases, a classical ferrofluid undergoes a Rosensweig …
