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 …

Feshbach resonances are the essential tool to control the interaction between atoms in
ultracold quantum gases. They have found numerous experimental applications, opening up …

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 …

In most cosmological models, rapid expansion of space marks the first moments of the
Universe and leads to the amplification of quantum fluctuations. The description of …

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 …

Attractive Bose-Einstein condensates can host two types of macroscopic self-bound states:
bright solitons and quantum droplets. Here, we investigate the connection between them …

According to the mean-field theory a condensed Bose-Bose mixture collapses when the
interspecies attraction becomes stronger than the geometrical average of the intraspecies …

The problem of an impurity particle moving through a bosonic medium plays a fundamental
role in physics. However, the canonical scenario of a mobile impurity immersed in a Bose …

We calculate the energy of one-and two-dimensional weakly interacting Bose-Bose mixtures
analytically in the Bogoliubov approximation and by using the diffusion Monte Carlo …

Anderson localization of waves in disordered media was originally predicted fifty years ago,
in the context of transport of electrons in crystals. The phenomenon is much more general …
