| Outline of Final Research Achievements |
Hadrons, such as nucleons and mesons, usually exist as spherical wave functions. When the system is in an extremely anisotropic environment (e.g., in an electromagnetic field), they are expected to have an anisotropic shape. Although electromagnetic fields strong enough to deform hadrons do not exist in our immediate environment, they are expected to occur realistically in relativistic heavy-ion collisions using particle accelerators and in magnetars. In this study, we developed theory and numerical method to elucidate the properties of hadrons under such an anisotropic environment and predicted novel physical phenomena.

| Academic Significance and Societal Importance of the Research Achievements |
本研究の主な研究対象はハドロン系やクォーク系（ディラック粒子系）であるが、研究成果として予言・解明された物理現象の数々は原子系・核子少数系・固体物性系などのその他の量子系へと拡張できる普遍的な概念であり、非等方環境における量子少数系・多体系の一般的な理解を深化させることにつながるという意味でも意義のある成果である。
