]]>Low-energy effective theories have become a powerful tool in nuclear physics and elsewhere in the past several decades. This paper describes a large amount of experimental data in this framework as “pairing rotational bands” with just a few parameters. The pairing rotational tensor is akin to a moment of inertia in the gauge space of two interacting superfluids. Its eigenvectors rotate with respect to the ($N$,$Z$) coordinate system, and they approximately point in the direction of the valley of $\beta $ stability and perpendicular to it. Combining superfluidity with deformation shows that the lowest-lying excitations in atomic nuclei are model-independent and based on emergent symmetry breaking.
