In a mean-field description of superfluidity, particle number and gauge angle are treated as quasiclassical conjugated variables. This level of description was recently used to describe nuclear reactions around the Coulomb barrier. Important effects of the relative gauge angle between two identical superfluid nuclei (symmetric collisions) on transfer probabilities and fusion barrier have been uncovered. A theory making contact with experiments should at least average over different initial… 
Microscopic description of pair transfer between two superfluid Fermi systems. II. Quantum mixing of time-dependent Hartree-Fock-Bogolyubov trajectories
While superfluidity is accurately grasped with a state that explicitly breaks the particle number symmetry, a precise description of phenomena like the particle transfer during heavy-ion reactions
Combining phase-space and time-dependent reduced density matrix approach to describe the dynamics of interacting fermions
The possibility to apply phase-space methods to many-body interacting systems might provide accurate descriptions of correlations with a reduced numerical cost. For instance, the so-called stochastic
Empirical evidence of the effect of superfluidity on the fusion barrier
Background: Several Time-Dependent Hartree-Fock-Bogoliubov (TDHFB) calculations predict that the super- fluidity enhances the fluctuations of the fusion barrier. This effect is not fully understood
The Time-Dependent Generator Coordinate Method in Nuclear Physics
The emergence of collective behaviors and the existence of large amplitude motions are both central features in the fields of nuclear structure and reactions. From a theoretical point of view,
Counting statistics in finite Fermi systems: Illustrations with the atomic nucleus
We analyze here in details the probability to find a given number of particles in a finite volume inside a normal or superfluid finite system. This probability, also known as counting statistics, is
Density-constrained time-dependent Hartree-Fock-Bogoliubov method
Background: The Density-constraint Time-dependent Hartree-Fock method is currently the tool of choice to predict fusion cross-sections. However, it does not include pairing correlations, which have
Determination of $1p$ and $2p$ stripping excitation functions for $^{16}$O+$^{142}$Ce using a Recoil Mass Spectrometer
We report the first direct measurement of differential transfer cross sections using a Recoil Mass Spectrometer. Absolute differential 1p and 2p-stripping cross sections at θc.m. = 180 ◦ have been

Effect of pairing on one- and two-nucleon transfer below the Coulomb barrier: a time-dependent microscopic description
The effect of pairing correlation on transfer reaction below the Coulomb barrier is investigated qualitatively and quantitatively using a simplified version of the Time-Dependent Hartree-Fock + BCS
Solitonic Excitations In Collisions Of Superfluid Nuclei
We investigate the role of the pairing field dynamics in low-energy heavy ion reactions within the nuclear time-dependent density functional theory extended to superfluid systems. Recently, we have
Phase operators and blurring time of a pair-condensed Fermi gas
Due to atomic interactions and dispersion in the total atom number, the order parameter of a pair-condensed Fermi gas experiences a collapse in a time that we derive microscopically. As in the
Stochastic quantum dynamics beyond mean field
Mean-field approaches where a complex fermionic many-body problem is replaced by an ensemble of independent particles in a self-consistent mean field can describe many static and dynamical aspects.
Colloquium: Exactly solvable Richardson-Gaudin models for many-body quantum systems
The use of exactly solvable Richardson-Gaudin models to describe the physics of systems with strong pair correlations is reviewed. The article begins with a brief discussion of Richardson's early

TLDR
It is demonstrated how the variations of the total kinetic energy of the fragments can be traced back to the energy stored in the superfluid junction of colliding nuclei.
