“…First, since we typically use a Hamiltonian that is pre-processed through a free-space SRG evolution, all other operators that are used in conjunction with the eigenstates have to undergo a consistent SRG transformation. As discussed earlier, such a unitary transformation [63], see [59] for more details.…”

One of the overarching goals in nuclear science is to understand how the nuclear chart emerges from the underlying fundamental interactions. The description of the structure of nuclei from first principles, using ab initio methods for the solution of the many-nucleon problem with inputs from chiral effective field theory, has advanced dramatically over the past two decades. We present an overview over the available ab initio tools with a specific emphasis on electromagnetic observables, such as multipole moments and transition strengths. These observables still pose a challenge for ab initio theory and are one of the most exciting domains to exploit synergies with modern experiments. Precise experimental data are vital for the validation of the theory predictions and the refinement of ab initio methods. We discuss some of the past and future experimental efforts highlighting these synergies. This article is part of the theme issue ‘The liminal position of Nuclear Physics: from hadrons to neutron stars’.

“…We acknowledge that the ab initio method is interpreted differently by different people; see, e.g., Refs. [26][27][28][29][30][31][32][33]. In nuclear physics, the evolution of ab initio and its wide application reflect the creativity and innovation of the scientists who perform ab initio computations.…”
