We review the notion of symmetry breaking and restoration within the frame of nuclear energy density functional methods. We focus on key differences between wave-function- and energy-functional-based methods. In particular, we point to difficulties to formulate the restoration of symmetries within the energy functional framework.

We review the notion of symmetry breaking and restoration within the frame of nuclear energy density functional methods. We focus on key differences between wave-function-and energy-functional-based methods. In particular, we point to difficulties encountered within the energy functional framework and discuss new potential constraints on the underlying energy density functional that could make the restoration of broken symmetries better formulated within such a formalism. We refer to Ref.1 for details.

A summary is given of recent work that provides evidence that the functional form of of the nuclear energy density functional, the rearrangement of the self-consistent mean field when changing neutron and proton number, and explicit fluctuations in collective degrees of freedom should be considered simultaneously when analyzing the evolution of shell structure in terms of nuclear energy density functional methods.
