The purpose of this project is to explore the design of artificial molecules based on spin cavitronics systems. During the excution of this project, reseearch is conducted and two academic papers are published, one of which is published on Physical Review B about the prediction of chiral cavity polaritons and another one is published on Journal of the Physical Society of Japan about unidirectional pumping of surface acoustic waves. During te project, the researcher has been invited to write chapter about indrect coupling between magnets. The chapter is to be published on 2021 Magnonics Roadmap. Another research about magnetic texture based neuromorphic computing is also supported by the project and is under submission.

该项目的目的是探索基于自旋空电子系统的人造分子的设计。本项目实施过程中，进行了研究并发表了两篇学术论文，其中一篇关于手性腔极化子预测的论文发表在Physical Review B上，另一篇关于表面声波单向泵浦的论文发表在Journal of the Physical Society of Japan上。在该项目期间，研究人员受邀撰写有关磁体之间间接耦合的章节。本章将在 2021 年 Magnonics 路线图上发布。另一项关于基于磁性纹理的神经拟态计算的研究也得到了该项目的支持，正在提交中。
