Contribution

It introduces a microscopic model showing the significant role of continuum coupling in superfluid behavior in nuclear systems at the drip line.

Findings

Continuum coupling impacts superfluid suppression and persistence.

Reentrant pairing occurs at certain temperatures.

Nuclear structure influences superfluid phases.

Abstract

Based on a microscopic description of superfluidity in overflowing nuclear systems, it is shown that continuum coupling plays an important role in the suppression, the persistence and the reentrance of pairing. In such systems, the structure of the drip-line nucleus determines the suppression and the persistence of superfluidity. The reentrance of pairing with increasing temperature leads to additional critical temperatures between the normal and superfluid phases.
