Pairing correlations of cold fermionic gases at overflow from a narrow to a wide harmonic trap

TL;DR

This paper investigates how superfluid pairing in cold fermionic gases changes as they transition from a narrow to a wide harmonic trap, using Hartree-Fock-Bogoliubov theory to connect experimental advances with theoretical insights.

Contribution

It provides a theoretical analysis of pairing correlations during the overflow transition in fermionic gases, linking recent experimental capabilities with detailed modeling.

Findings

Pairing correlations vary significantly during overflow transition.

The study offers predictions for experimental observations of superfluid behavior.

Insights into the effects of rapidly changing external potentials on pairing.

Abstract

Within the context of Hartree-Fock-Bogoliubov theory, we study the behavior of superfluid Fermi systems when they pass from a small to a large container. Such systems can be now realized thanks to recent progress in experimental techniques. It will allow to better understand pairing properties at overflow and in general in rapidly varying external potentials.
