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 review the BCS to Bose–Einstein condensation (BEC) crossover scenario which is
based on the well known crossover generalization of the BCS ground state wavefunction …

Nuclear matter and finite nuclei exhibit the property of superfluidity by forming Cooper pairs.
We review the microscopic theories and methods that are being employed to understand the …

This review treats several pairing-related phenomena in nuclear systems, ranging from
superfluidity in neutron stars to the gradual breaking of pairs in finite nuclei. It focuses on the …

The foundation of the local energy-density functional method to describe the nuclear ground-
state properties is given. The method is used to investigate differential observables such as …

Four-particle correlations in fermion systems at finite temperatures are investigated with
special attention to the formation of a condensate. Instead of the instability of the normal …

We analyze the possibility that due to their superfluid properties some compact astrophysical
objects may contain a significant part of their matter in the form of a Bose-Einstein …

The present understanding of the structure of the Hoyle state in C 12 is reviewed. Most of the
theoretical approaches to the Hoyle state are shortly summarized. The corresponding results …

The spatial structure of the neutron Cooper pair in superfluid low-density uniform matter is
analyzed by means of BCS calculations employing a bare force and the effective Gogny …

We present results for the 3 P 2− 3 F 2 pairing gap in neutron matter with several realistic
nucleon-nucleon potentials, in particular with recent phase-shift-equivalent potentials. We …
