This article reviews theoretical and experimental advances in Efimov physics, an array of
quantum few-body and many-body phenomena arising for particles interacting via short …

This article reviews theoretical and experimental developments for one-dimensional Fermi
gases. Specifically, the experimentally realized two-component delta-function interacting …

Self-bound quantum droplets are a newly discovered phase in the context of ultracold
atoms. In this Letter, we report their experimental realization following the original proposal …

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 …

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 …

A recent rejuvenation of experimental and theoretical interest in the physics of few-body
systems has provided deep, fundamental insights into a broad range of problems. Few-body …

The variational method complemented with the use of explicitly correlated Gaussian basis
functions is one of the most powerful approaches currently used for calculating the …

Nuclear halos emerge as new degrees of freedom near the neutron and proton driplines.
They consist of a core and one or a few nucleons which spend most of their time in the …

Advancing our understanding of non-equilibrium phenomena in quantum many-body
systems remains one of the greatest challenges in physics. Here we report on the …

Superfluidity in its various forms has been of interest since the observation of frictionless flow
in liquid helium II,. In three spatial dimensions it is conceptually associated with the …
