Fixed points of finite groups acting on generalised Thompson groups
, 2010 We study centralisers of finite order automorphisms of the generalised Thompson groups Fn, ? and conjugacy classes of finite sub- groups in finite extensions of Fn, ?. In particular we show that centralisers of finite automorphisms in Fn, ? are either of

Multidimensional‐Encoded High‐Fidelity Spectrometers With a Floating‐Base Bipolar Junction
Advanced Functional Materials, EarlyView.A floating‐base bipolar junction photodetector enables multidimensional spectral encoding through synergistic gate‐ and drain‐bias modulation of interfacial barrier matching. The resulting complementary spectral responses form a diverse, weakly correlated response matrix, enabling robust and high‐fidelity spectral reconstruction even at sub‐nanoampere ...

Prime order derangements in primitive permutation groups
, 2011 Let G be a transitive permutation group on a finite set Ω of size at least 2. An element of G is a derangement if it has no fixed points on Ω. Let r be a prime divisor of |Ω|.

GeS as an Emerging OTS Material: Atomic Structure and Modeling of ON/OFF Switching
Advanced Functional Materials, EarlyView.The structural puzzle of glassy GeS, an advanced memory‐selector material, has finally been disentangled, revealing a patchwork of mixed tetrahedral and trigonal species. Under a high electric field, over‐ and under‐coordinated Ge and S defects, together with three‐membered rings, form an interconnected network associated with localized and extended ...

Configuration‐Encoded Cell Alignment by Light‐Gated Silicon Photovoltaic Microcell Arrays
Advanced Functional Materials, EarlyView.Light‐gated silicon photovoltaic microcells convert pulsed illumination into localized electrical cues. Arranging otherwise similar microcells into four‐lobed, six‐lobed, or circular patterns directs fibroblasts into corresponding local arrangements without wired stimulation.

Dirac Semimetallicity Enabled by Stripe Antiferromagnetism in Monolayer FeSe
Advanced Functional Materials, EarlyView.In monolayer FeSe, stripe antiferromagnetic order selectively breaks mirror symmetry, enabling odd inter‐orbital hybridization between opposite‐parity Fe 3d states. This mechanism stabilizes symmetry‐protected Dirac nodes with nontrivial Wilson‐loop topology and edge states, accompanied by a strong orbital diamagnetic susceptibility as an experimental ...

Finite groups with many normalizers
summary:A group $G$ is said to have dense normalizers if every nonempty open interval in its subgroup lattice $L(G)$ contains the normalizer of a certain subgroup of $G$. We find all finite groups satisfying this property.

Emergence of a Hexagonal Fe2S2 Single Layer Without a Bulk Counterpart via Phase Transformation
Advanced Functional Materials, EarlyView.Upon annealing, single‐layer Mackinawite iron sulfide transforms into a previously unknown hexagonal Fe2S2${\rm Fe}_2{\rm S}_2$ phase with β$\beta$‐CuI structure. STM, LEED, and first‐principles calculations identify the structure and show that electronic correlations and magnetic order are important for its stability.

Advanced Functional Materials, EarlyView.All‐epitaxial and scalable ferromagnetic/non‐magnetic Fe5−xGeTe2/WSe2 van der Waals (vdW) heterostructures exhibiting room‐temperature magnetism and perpendicular magnetic anisotropy (PMA) are realized. The system displays proximity‐tuned magnetic anisotropy, thickness‐dependent unconventional Hall effects, and temperature‐dependent sign reversal of ...
