| Outline of Annual Research Achievements |
In the fiscal year 2022 we continued to carry out research on magnonics and magnon chemistry and published many papers in leading journals. The highlights of our theoretical work were (1)
Identification of long-distance spin transport by phonons that leads to a new form of a magnonic hydrogen molecule that is bonded by phonons. (2) We carried out our first steps in the field of van der Waals magnets and helped interpreting experiments in the Groningen group in the Netherlands, (3) We predicted a procedure to construct magnon cat states by bonding with a superconducting q-bit, which is a quantum magnon chemistry issue, (4) We pointed out the analogies and differences between magnons and ferrons that pave the wave of making heteromolecular states of both magnetic and electric character. (5) We explained experiments of non-local and non-linear magnon generation by magnetic nanowires on magnetic thin films.

| Current Status of Research Progress |
Current Status of Research Progress
1: Research has progressed more than it was originally planned.
Reason
The project is proceeding beautifully, with most objectives being addressed and solved on schedule, but with the years new challenges appear in the form of new materials that emerge as promising objects to study the magnon chemistry as well as in managing the manpower.
|
| Strategy for Future Research Activity |
We will focus on the new challenges for magnon chemistry that only very recently emerged in the form of new materials, viz. ferroelectrics, van der Waals multi-layered and 2D (anti)ferromagnets, and most recently altermagnets.
