Recently, with new Time-dependent Hartree-Fock-Bogoliubov codes, the effects of the relative gauge angle in reactions have been studied. It has been shown that the fusion barrier is changed when the initial relative gauge angle between the two fragments is changed. In addition, the Josephson effect which induces a current between the two fragments has also been studied. Nevertheless, in nuclear reactions, the number of particles is small and initially fixed. Then to understand the results predicted by TDHFB it is necessary to restore the initial particle-number symmetries.
