Outline of Annual Research Achievements

研究最終年度であることに留意し、バルクエッジ対応の普遍性を確立すべくまとめの研究を行った。
理論的研究に関して、高次トポロジカル相のバルク・コーナー対応や、新概念である平方根トポロジカル相でのバルク・エッジ対応を解明した。強相関トポロジカルポンプでのバルク・エッジ対応と逐次トポロジカル転移を解明した。バルク・エッジ対応が支配する新分野として、熱伝導現象におけるバルクエッジ対応を確立した。更に自然科学を越えて社会現象を記述する二次元ネットワークにおけるゲーム理論でチャーン数を定義しバルク・エッジ対応を確立した。
冷却原子に関しては、蒸発冷却の条件の最適化・磁場の安定化を行い、Rb原子の人工次元を用いたトポロジカル原子レーザーの再現性を向上させ、実験パラメータ領域を拡大した。トポロジカル超流動に向けた実験ではEr原子のボース凝縮を実現し、フェルミ同位体Er原子とYb原子のフェッシュバッハ共鳴を観測した。更に、明確な境界を有するYb原子無欠陥光ピンセットアレーの生成とYb量子気体顕微鏡の開発に成功した。
放射光ARPES実験に関して超伝導体ZrP2-xSex, HfP2-xSexについて、ディラック線ノードと表面バンドを同時に観測した。反強磁性トポロジカル絶縁体MnBi2Te4の表面バンドのエネルギーギャップを第一原理計算を併用して解析し、表面欠陥による局所電場が重要性を解明した。
フォトニック結晶実験に関して，量子ドットを含むバレーフォトニック結晶スローライト導波路において、スローライト効果による発光寿命の短縮と単一光子のトポロジカルエッジ状態を介した伝搬の観測に成功した。また、ナノフォトニクス系では実現が困難な四重極相におけるコーナー状態を示すフォトニック結晶の設計を見出し、構造揺らぎが波長やQ値に及ぼす影響について、トリビアルなフォトニック結晶共振器と比較し議論した。
