Outline of Research at the Start

量子力学の世界では真空はゆらいでおり、そのゆらぎが物質間の力(カシミール力)を生むことがある。特に電気的に中性な物質に対してはカシミール力が重要となり、~1μmの物質においては最も支配的な力となる。
この力の制御方法の理解は工学的な応用において必須であるだけでなく、宇宙論における宇宙項問題、素粒子物理学における余剰次元の有限サイズでの安定化、生物学における二重膜構造の安定化、化学における分子間力における重要性も指摘されている。
本研究では、ゆらぎを生じている場における相互作用を考慮することにより、カシミール力の統括的理解と相互作用によるCasimir力の制御方法の提案を目的としている。

Outline of Final Research Achievements

In this study, based on the objective of investigating the influence of Casimir forces originating from the structure of vacuum in quantum many-body systems and proposing methods for their utilization, various topics were explored. These include analysis of vacuum structure in many-body systems, effects of phase transitions on Casimir effects, analysis of thermodynamic work extractable during parameter modulation, and methods for estimating deviations from vacuum states with and without quantum many-body correlations in the presence of noise. As a result, insights into the stability of non-uniform condensates in systems subjected to magnetic fields, peculiar behavior of Casimir forces due to phase transitions induced by magnetic fields, generation of work due to periodic modulation of parameters, and instability of vacuum states in spin-1 bosonic systems have been revealed.

Academic Significance and Societal Importance of the Research Achievements

本研究では真空の揺らぎから生じる力(カシミール力)に関連する統括的な研究を行った。この力は至る所で現れるため、微小な素子や生体膜における影響から、高エネルギー物理学における余剰次元のコンパクト化の起源の可能性なども調べられている。本研究ではカシミール効果における量子多体効果の影響とそれを用いた制御、そして応用方法の提案など、今後の発展へとつながる研究を行ってきた。研究期間を通して論文12報と招待セミナー5件、国際会議発表(口頭発表5件, ポスター発表8件)など様々な媒体を通して成果を報告してきた。この研究がさらに深まることにより、実際の応用や自然現象のより深い理解へと繋がることが期待される。
