| 研究開始時の研究の概要 |
Spin cavitronics is the inter-discipline of spintronics and cavity quantum electrodynamics, in which magnons strongly couple with photons and phonons to produce rich new physics. Multiple magnetic spheres can interact with each other by the virtual exchange of microwaves photons inviting, analogies with chemical bonding. With the help of both analytical derivations and numerical calculation, we propose designing bosonic magnonic molecules with different "atoms", configurations, and customized interactions. These molecules from a new platform for studying macroscopic quantum effects.

| 研究実績の概要 |
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.
