研究人员开发了eSpinor，一种新颖的SU(2)-等变图神经网络，旨在通过传播旋量特征来预测分子磁性。这种方法提高了钴单分子磁体候选物零场分裂的预测精度，并增强了镝探针的真实电子自旋相关性，即使在没有针对甲醇等不同环境进行重新训练的情况下也是如此。研究结果表明，SU(2)-等变旋量消息传递为分子磁性提供了有价值的归纳偏置，强调了基于特定物理可观测量的准确性进行模型选择的重要性。 AI

影响这项研究引入了一种新颖的图神经网络架构，提高了分子磁性的预测精度，有望加速该领域的材料发现。

SU(2)-Equivariant Spinor Message Passing for Molecular Magnetism

arXiv:2610.29111v1 Announce Type: cross Abstract: Predicting molecular magnetism often requires electronic-structure calculations with spin-orbit coupling (SOC), which are costly to repeat across many molecules. The underlying electronic states can transform as spinors, yet equiv…
