Several classes of plane partitions with the same generating function (Representation Theory and its Combinatorial Aspects)
StrikerとWilliamsはrc-posetという概念を定義してpromotionやrowmotionをtoggleという概念を使ってrc-posetの順序イデアル全体になす分配束に一般化できることを示した. また, 交代符号行列全体の成す分配束に対して, join-irreducibleな元全体の成す部分半順序集合AnがA型のpositive root posetsΦ(Ak)を貼り合わせてできることを示した. この原稿の中で我々は点対称な交代符号行列の成す有限分配束について調べる.

Ladder‐Type Benzene‐Perylene Dyes with Efficient Laser Properties in the Near‐IR by Detracting/Activating Low/High Frequency Vibronic Modes

Advanced Functional Materials, EarlyView.
The NNR‐n series of oligomeric nanographenes delivers exceptional emission performance. This work shows that this performance is originated by their ladder‐type structure, which effectively deactivates low‐frequency vibronic modes. This deactivation neglects the main pathway for non‐emissive deactivation, even in the near‐infrared region. The potential

Low‐Symmetry Weyl Semimetals: A Path to Ideal Topological States

Advanced Functional Materials, EarlyView.
This study presents a theoretical framework for realizing ideal Weyl semimetals, where Weyl nodes are well‐isolated at the Fermi level. The approach is exemplified in the low‐symmetry material Cu2SnSe3, which exhibits tunable topological phases, current‐induced orbital magnetization, and a strong circular photogalvanic effect, making it a promising ...
