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 …

The crossover from weak-coupling Bardeen-Cooper-Schrieffer (BCS) pairing to a Bose-
Einstein condensate (BEC) of tightly bound pairs, as a function of the attractive interaction in …

Supersolidity combines superfluid flow with long-range spatial periodicity of solids, two
properties that are often mutually exclusive. The original discussion of quantum crystals and …

Superconductivity and magnetism generally do not coexist. Changing the relative number of
up and down spin electrons disrupts the basic mechanism of superconductivity, where …

We describe the fissioning dynamics of Pu 240 from a configuration in the proximity of the
outer fission barrier to full scission and the formation of the fragments within an …

Recent experiments with ultra-cold atoms have demonstrated the possibility of realizing
fermionic superfluids with imbalanced spin populations experimentally. We discuss how …

We review the concepts and the present state of theoretical studies of spin-imbalanced
superfluidity, in particular the elusive Fulde–Ferrell–Larkin–Ovchinnikov (FFLO) state, in the …

The properties of low-density neutron matter are important for the understanding of neutron
star crusts and the exterior of large neutron-rich nuclei. We examine various properties of …

Solitons—solitary waves that maintain their shape as they propagate—occur as water waves
in narrow canals, as light pulses in optical fibres and as quantum mechanical matter waves …

We present an overview of recent developments in species-imbalanced ('polarized')
Feshbach-resonant Fermi gases. We summarize the current status of thermodynamics of …
