A theoretical analysis of binary collisions of quantum droplets under feasible experimental conditions is reported. Droplets formed from degenerate dilute Bose gases made up from binary mixtures of ultracold atoms are considered. Reliable expressions for the surface tension of the droplets are introduced based on a study of low energy excitations of their ground state within the random phase approximation. Their relevance is evaluated considering an estimation of the expected excitation energy… 



Collisions of Self-Bound Quantum Droplets.

The study of binary collisions between quantum droplets formed by an attractive mixture of ultracold atoms is reported, providing the first evidence of the liquidlike nature of quantum Droplets in the large N limit, where their behavior closely resembles that of classical liquid droplets.

Quantum liquid droplets in a mixture of Bose-Einstein condensates

This work reports on the observation of droplets solely stabilized by contact interactions in a mixture of two Bose-Einstein condensates, and demonstrates that they are several orders of magnitude more dilute than liquid helium by directly measuring their size and density via in situ imaging.

Self-bound droplets of a dilute magnetic quantum liquid

Three-dimensional self-bound quantum droplets of magnetic atoms of ultracold atoms are observed in a trap-free levitation field and it is found that this dilute magnetic quantum liquid requires a minimum, critical number of atoms, below which the liquid evaporates into an expanding gas as a result of the quantum pressure of the individual constituents.

Dilute dipolar quantum droplets beyond the extended Gross-Pitaevskii equation

Dipolar quantum droplets are exotic quantum objects that are self-bound due to the subtle balance of attraction, repulsion and quantum correlations. Here we present a systematic study of the critical

Observation of Quantum Droplets in a Strongly Dipolar Bose Gas.

By systematic measurements on individual droplets it is demonstrated quantitatively that quantum fluctuations mechanically stabilize them against the mean-field collapse, and the interference of several droplets indicating that this stable many-body state is phase coherent.

Observation of quantum droplets in a heteronuclear bosonic mixture

We report on the formation of heteronuclear quantum droplets in an attractive bosonic mixture of 41K and 87Rb. We observe long-lived self-bound states, both in free space and in an optical waveguide.

Dilute quantum droplets.

Under these conditions both Bose-Einstein and Fermi-Dirac systems could become self-bound and either boson droplets or fermion "designer nuclei" of various sizes and densities could be manufactured.

Quantum Mechanical Stabilization of a Collapsing Bose-Bose Mixture.

It is shown that in a wide range of parameters its excitation spectrum lies entirely above the particle emission threshold and the droplet thus automatically evaporates itself to zero temperature, the property potentially interesting by itself and from the viewpoint of sympathetic cooling of other systems.

Three-dimensional droplets of swirling superfluids

A new method for the creation of 3D solitary topological modes, corresponding to vortical droplets of a two-component dilute superfluid, is presented. We use the recently introduced system of

Ultradilute quantum liquid drops

Using quantum Monte Carlo methods we have studied dilute Bose-Bose mixtures with attractive interspecies interaction in the limit of zero temperature. The calculations are exact within some
