We are pleased to announce an international symposium "20 Year Anniversary of Nuclear Shell Evolution by Tensor Force" to be held from October 21–25, 2025, in Wuxi, Jiangsu Province, China. Co-organized by Prof. Takaharu Otsuka (University of Tokyo) and Lang Liu (Jiangnan University), and hosted by Jiangnan University, this event marks two decades of transformative insights into nuclear shell evolution, driven by the tensor force's critical role in nuclear structure.

The atomic nucleus, a quantum many-body system, reveals intricate nucleon interactions with spin- and isospin-dependent components. While traditional shell-model frameworks accounted for stable nuclei with magic numbers (N, Z = 8, 20, 28, 50, 82, 126), exotic nuclei—short-lived with large N/Z asymmetry — exhibit shifts in these magic numbers. These shifts, significantly influenced by the tensor force, have reshaped nuclear physics, offering a deeper understanding of nuclear interactions through experimental-theoretical interplay.

This symposium will convene global experts to reflect on milestones, discuss recent breakthroughs, and chart future directions. Key topics include:

•  Tensor force effects on shell evolution

•  Shell model and Monte Carlo shell model advancements

•  Experimental evidence from exotic nuclei

•  Theoretical innovations in nuclear force modeling

•  Connections to nuclear astrophysics
