论文摘要
储层计算是预测湍流的有力工具，其简单的架构具有处理大型系统的计算效率。然而，其实现通常需要完整的状态向量测量和系统非线性知识。我们使用非线性投影函数将系统测量扩展到高维空间，然后将其输入到储层中以获得预测。我们展示了这种储层计算网络在时空混沌系统上的应用，该系统模拟了湍流的若干特征。我们表明，使用径向基函数作为非线性投影器，即使只有部分观测并且不知道控制方程，也能稳健地捕捉复杂的系统非线性。最后，我们表明，当测量稀疏、不完整且带有噪声，甚至控制方程变得不准确时，我们的网络仍然可以产生相当准确的预测，从而为实际湍流系统的无模型预测铺平了道路。
Recent experiments [Persky {\it{et al.}}, Nature {\bf{607}}, 692 (2022)] demonstrate a magnetic memory effect in 4Hb-$\mathrm{TaS_2}$ above its superconducting transition temperature, where Abriokosov vortices are generated spontaneously by lowering temperature at zero magnetic field after field training the normal state. Motivated by the experiment, we propose the chiral quantum spin liquid (QSL) stabilized in the constituent layers of 4Hb-$\mathrm{TaS_2}$ as a mechanism. We model 4Hb-$\mathrm{TaS_2}$ as coupled layers of the chiral QSL and superconductor. Through the Kondo coupling between the localized moments and conduction electrons, there is mutual transmutation between spinons and vortices during the thermal cycling process, which yields magnetic memory effect as observed in experiments. We also propose a mechanism to stabilize the chiral and nematic superconductivity in 4Hb-$\mathrm{TaS_2}$ through the Kondo coupling of conduction electrons to the chiral QSL. Our results suggest 4Hb-$\mathrm{TaS_2}$ as an exciting platform to explore the interplay between QSL and superconductivity through the Kondo effect.
