  "abstract": "The evolution of nuclear shell structures at $N=32$ and 34 are studied in nuclei far from the stability line using effective interactions derived from realistic nuclear forces. The state-of-the-art \\textit{ab initio} in-medium similarity renormalization group method is used for this purpose. The calculated results are consistent with experimental observations, and predictions are made where experimental data are unavailable. The shell gaps are analyzed from the evolution of effective single-particle energies, and various facets of nuclear interaction, such as central, spin-orbit, and tensor parts, are addressed by spin-tensor decomposition of the effective interactions. The roles played by these components in the development of shell closure, particularly by the tensor components, were highlighted throughout the study. Then, we discussed the low-lying structure of the exotic $N=32$ isotones below Ca. The present work demonstrates essential components of nuclear force in shaping magic numbers far from stability and provides deeper insights into the structure of exotic nuclei.",
