Short-wavelength repulsive potentials for quantum gases allow one to realize new systems
and to study new phenomena. Here we report the realization of repulsive optical potentials …

Since its discovery, superfluidity [1, 2] remains one of the most remarkable phenomena in
quantum physics. The onset of the quantum regime in liquid helium is visually striking, when …

We analyze the pinning of vortices for a stationary rotating dipolar supersolid along the low-
density paths between droplets as a function of the rotation frequency. We restrict ourselves …

Glitches are sudden spin-up events that interrupt the gradual spin-down of rotating neutron
stars. They are believed to arise from the rapid unpinning of vortices in the neutron star inner …

The task of experimentally investigating the inherently dual properties of a supersolid, a
simultaneous superfluid and solid, has become more critical following the recent …

In classical inviscid fluids, parallel vortices perturbed by Kelvin waves may exhibit the Crow
instability, where the mutual interaction of the Kelvin modes renders them dynamically …

The supersolid phase of a dipolar Bose-Einstein condensate has an intriguing excitation
spectrum displaying a band structure. Here, the dressing of an impurity in a one-dimensional …
