5,11‐Di(thiophen‐2‐yl)Tetracene: A Novel Tetracene Derivative for Efficient Singlet Fission with Enhanced Physical and Chemical Stability in Thin Films

open access: yesAdvanced Functional Materials, EarlyView.
In this work, a new tetracene derivative, 5,11‐di(thiophen‐2‐yl)tetracene (2T‐Tc) is introduced, exhibiting enhanced physical and chemical stability, and retaining favorable singlet fission kinetics with near unity triplet pair yield in thin films.

On the nilpotent complex of simple groups of Lie type

open access: yesHokkaido Mathematical Journal, 2003
Let \(G\) be a finite group and \(t(G)\) be the number of connected components of the prime graph of \(G\), and \(Nl(G)\) be the partially ordered set of nilpotent subgroups of \(G\). In her previous paper [Commun. Algebra 23, No. 5, 1825-1836 (1995; Zbl 0831.20021)], the authoress proved that \(Nl(G)\) is not connected if and only if \(t(G)>1\) and ...

Exploring Electronic States and Ultrafast Electron Dynamics in AlInP Window Layers: The Role of Surface Reconstruction

open access: yesAdvanced Functional Materials, EarlyView.
This study examines the surface characteristics of AlInP (001), crucial for advanced solar cells and photoelectrochemical devices. Using theoretical modeling and experiments, it identifies how phosphorus‐rich and indium‐rich surfaces create mid‐gap states that pin the Fermi level and influence ultrafast electron dynamics.

Chern-Simons theory, Ehrhart polynomials, and representation theory

open access: yesJournal of High Energy Physics
The Hilbert space of level q Chern-Simons theory of gauge group G of the ADE type quantized on T 2 can be represented by points that lie on the weight lattice of the Lie algebra g up to some discrete identifications.

On the 1-Cohomology of Finite Groups of Lie Type

open access: yesJournal of Algebra, 1997
Let \(G\) be a simply connected algebraic group defined and split over \(\mathbb{F}_p\) and let \(G(n)\) denote the rational points over \(\mathbb{F}_{p^n}\). The main result of this paper is to determine a uniform bound, \(N(G,p)\), such that for all \(n>N(G,p)\) and all \(p^n\) restricted highest weights, \(\lambda\), restriction gives an isomorphism

Discovery of an Intrinsic Antiferromagnetic Semiconductor EuSc2Te4 With Magnetism‐Driven Nonlinear Transport

open access: yesAdvanced Functional Materials, EarlyView.
EuSc₂Te₄, an antiferromagnetic semiconductor, exhibits a nonlinear Hall effect (NLHE) characterized by quadratic current–voltage behavior. Combined experimental and theoretical studies reveal that this NLHE is linked to its antiferromagnetism and involves contributions from the quantum metric.

Cohomology and Deformations of Relative Rota–Baxter Operators on Lie-Yamaguti Algebras

open access: yesMathematics
In this paper, we establish the cohomology of relative Rota–Baxter operators on Lie-Yamaguti algebras via the Yamaguti cohomology. Then, we use this type of cohomology to characterize deformations of relative Rota–Baxter operators on Lie-Yamaguti ...
