RIKEN Center for Emergent Matter Science (CEMS) was founded in 2013, bringing together top researchers in physics, chemistry, and electronics. Its mission is to elucidate the principles of emergent phenomena and explore their applications. The Institute for Solid State Physics (ISSP) was established in 1957 as a joint research institute in condensed matter physics. ISSP's missions are to conduct cutting-edge researches, to foster young talents, and to promote joint researches and collaborations. Both the institutes are aming at developing innovative new materials and constructing theoretical frameworks to benefit future human society.
Strengthening research capabilities of our country is a recent important issue. We believe cooperation between the two institutes can contribute to addressing this challenge. We thus organize this workshop to explore the current status and future possibilities of collaborative research between ISSP and CEMS, focusing on deepening mutual understanding.
Through this workshop, we aim to elucidate the strengths and shared research interests of both institutes, foster dynamic exchanges of ideas among participants to shape the direction of new research leveraging their expertise and experience and pinpoint potential collaborative projects.
理研創発物性科学研究センター（RIKEN-CEMS）は、2013年に物理、化学、エレクトロニクスのトップ研究者が集結して発足され、創発現象の学理を解明し、その応用への展開を拓くための研究が展開されています。物性研究所（ISSP）は、1957年に共同利用研究所として設立され、我が国の物性科学研究の発展に貢献すべく、研究、人材育成、共同利用、共同研究を行ってきました。
国際的な研究開発競争が激化する近年、我が国の研究力の強化は喫緊の課題であり、両研究所が協力し、切磋琢磨することで日本の科学研究の発展に貢献できると我々は考えています。本ワークショップは、両研究所の強みや研究テーマの共通点を明確にし、それぞれの専門知識や経験を結集して新たな研究の方向性について参加者が活発に意見交換し、可能な連携プロジェクトを特定することで、より具体的な協力の展望や新たな研究の展開の構築に結実させることを目指します。
