The main theme of this review is the many-body physics of vortices in quantum droplets of
bosons or fermions in the limit of small particle numbers. Systems of interest include cold …

A rapidly rotating Bose gas in the quantum Hall limit is usually associated with a melted
vortex lattice. In this work, we report a self-bound and visible triangular vortex lattice without …

Bose mixture quantum droplets display a fascinating stability that relies on quantum
fluctuations to prevent collapse driven by mean-field effects. Most droplet research focuses …

Quantized vortices have been observed in a variety of superfluid systems, from He 4 to
condensates of alkali-metal bosons and ultracold Fermi gases along the BEC-BCS …

We show that the rotation of trapped quantum mechanical particles with a repulsive
interaction can lead to vortex formation, irrespective of whether the particles are bosons or …

Quantum droplets may form out of a gaseous Bose-Einstein condensate, stabilized by
quantum fluctuations beyond mean field. Determining the ground state of a rotating binary …

We analyze the existence and characteristics of discrete vortex quantum droplets with
intrinsic topological charges S of up to 5 in two-component Bose-Einstein condensates in a …

We consider a binary bosonic condensate with weak mean-field (MF) residual repulsion,
loaded in an array of nearly one-dimensional traps coupled by transverse hopping. With the …

We study the surface modes of some of the vortex liquids recently found by means of exact
diagonalizations in systems of rapidly rotating bosons. In contrast to the surface modes of …

We address the effects of internal modes on the evolution dynamics of quantum droplets in
symmetric binary Bose-Einstein condensates. Angle-dependent internal modes and the …
