Speaker: 张雷教授，南京大学Time: 2026年4月23日10:00至12:00Location: 9号教学楼409摘要:希格斯粒子的发现确立了基本粒子质量源于电弱对称性破缺机制，是粒子物理学标准模型的巨大成功。但是电弱对称破缺的动力学机制及其热力学历史仍然未知，例如是一级相变还是二级相变。在LHC上，通过精确测量希格斯自耦合可以研究希格斯场的势能结构，从而理解电弱对称破缺的本质。此外，不同代(又称味道)的夸克、轻子等费米子的规范相互作用性质都一样，...

Modern nuclear physics aims to understand nuclear structure and decay properties from fundamental nucleon interactions. Phenomenological models successfully describe known data but lose predictive power for exotic nuclei and rare processes. Recent advances in ab initio methods employ ...

We introduce SEA-PINN, a novel architecture that incorporates a Squeeze-Excitation-like attention mechanism into physics-informed neural networks to dynamically recalibrate the importance of neurons across layers. A key feature of SEA-PINN is its highly stable initialization. On 17 out of 20 benchmark problems,...

Speaker: 徐凌霄 博士, (the Abdus Salam International Centre for Theoretical Physics)Time: 2025年12月29日·周一下午 14:00Location: 9号楼9409会议室Abstract: Motivated by recent advances in the generalization of global symmetries in quantum fieldtheory, we introduce a class of selection rules originating from non-invertible fusion algebras rather thanconventional group laws, which we refer to as non-invertible ...

Exploring heavy vector mesons of the J/ψ and Υ(1S) is crucial for understanding the quark gluon plasma (QGP) formed in heavy ion collisions. The influences of rotational effect on the properties of the J/ψ and the Υ(1S) are investigated by incorporating rotation medium into the holographic QCD. It is ...
