Ab Initio Computations of Strongly Deformed Nuclei

The capabilities of ab initio many-body methods for nuclear structure and reactions have expanded dramatically within recent years [1]. We have seen first converged calculations for nuclei as heavy as Pb208, a first attempt at a mass table up to the iron region, and efforts are now focusing on nuclei with complex intrinsic deformation. The progress in many-body theory has been accompanied by advances in surrogate modeling that now enable large-scale parameter exploration and statistical uncertainty quantification. These developments are crucial for meaningful comparisons with experiments, especially since ab initio nuclear theory inputs play an increasingly important role in precision fundamental symmetry research. In this talk, I will give a brief overview of the state of the art for the ab initio description of deformed nuclei. I will highlight key developments and achievements [2-6], and touch upon the challenges we will face in the years ahead.
