Abstract
In recent years, efforts have been made to account for super-fluidity in time-dependent mean-field description of nuclear dynamic [1–5]. Inclusion of pairing is important to achieve a realistic description of static properties of nuclei. Here,we show that pairing can also affect the nuclear motion. State of the art TDHF approach can describe from small to large amplitude collective motion as well as the collision between nuclei. Very recently, this microscopic approach has been improved to include pairing either in the BCS or HFB framework. Recent applications of the 3D TDHF + BCS (TDHF+BCS) model introduced in [4] will be presented. The role of super-fluidity on collective motion [6, 7], on one- and two-particle transfer [8] and on fission [9, 10] will be illustrated.
Highlights
Nuclear time-dependent mean-field based on the energy density functional approach is experiencing nowadays a renewal of interest [11,12,13,14,15,16]
It allows one to describe a wide variety of dynamical processes ranging from small to large amplitude collective motions, including nuclear reactions
The possibility to describe pairing in dynamical models is an important step in the field since (i) it allows to describe dynamical processes involving superfluid nuclei, that are the majority of nuclei in the nuclear chart; (ii) it opens the perspective to uncover expected or new dynamical phenomena emerging from pairing dynamics
Summary
Nuclear time-dependent mean-field based on the energy density functional approach is experiencing nowadays a renewal of interest [11,12,13,14,15,16]. The perspective to uncover expected or new dynamical phenomena emerging from pairing dynamics It is well known, especially in condensed matter that the occurrence of Cooper pairs can lead to new macroscopic effects like the occurrence of Josephson effect or vortex dynamic [17]. In this proceedings, we highlight recent progresses in the field and illustrate through applications how superfluidity can affect the nuclear motion either at the level of one nucleus or when two nuclei are involved like during Heavy-Ions collisions
