Neutron stars provide a window into the properties of dense nuclear matter. Several recent
observational and theoretical developments provide powerful constraints on their structure …

Spinor Bose gases form a family of quantum fluids manifesting both magnetic order and<?
format?> superfluidity. This article reviews experimental and theoretical progress in …

Lattice gauge theories, which originated from particle physics in the context of Quantum
Chromodynamics (QCD), provide an important intellectual stimulus to further develop …

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 …

In a joint experimental and theoretical effort, we report on the formation of a macrodroplet
state in an ultracold bosonic gas of erbium atoms with strong dipolar interactions. By precise …

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 …

Ultracold quantum gases offer a unique setting for quantum simulation of interacting many-
body systems. The high degree of controllability, the novel detection possibilities and the …

This report addresses topics and questions of common interest in the fields of ultra-cold
gases and nuclear physics in the context of the BCS–BEC crossover. By this crossover, the …

We have observed the Bose-Einstein condensation of an atomic gas in the (quasi) uniform
three-dimensional potential of an optical box trap. Condensation is seen in the bimodal …

We propose the existence of a lower bound on the energy of pure neutron matter (PNM) on
the basis of unitary-gas considerations. We discuss its justification from experimental studies …
