Spectroscopic Signatures of Doping in Thin Films of Semiconducting Single‐Walled Carbon Nanotubes
Small, EarlyView.This review presents an overview of the spectroscopic changes of semiconducting single‐walled carbon nanotubes upon chemical, electrochemical or electrostatic doping. The presence of holes or electrons directly affects visible to far‐infrared absorption, near‐infrared fluorescence and electroluminescence as well as Raman spectra, which enables in‐situ ...

Scalable Room‐Temperature Terahertz Graphene Cameras
Small Methods, EarlyView.ABSTRACT Terahertz (THz) imaging has emerged as a powerful tool for non‐destructive, label‐free analysis across several scientific disciplines, ranging from materials science to biomedical research. By capturing the spatial‐dependent information in a broad range of frequencies, this technique enables the identification of chemical composition ...

Transmon Qubit constraints on dark matter-nucleon scattering
Journal of High Energy PhysicsWe recently pointed out that power measurements of single quasiparticle devices can be used to detect dark matter. These devices have the lowest known energy thresholds, far surpassing standard direct detection experiments, requiring energy deposition ...

Unraveling the symmetry of Al5C3N
Acta Crystallographica Section B, EarlyView.From experimental and theoretical techniques employed in this thorough reexamination of the structure of Al5C3N, the crystal structure is better described in centrosymmetric space group P63/mmc (No. 194) rather than in the previously reported noncentrosymmetric space group P63mc (No. 186).High‐temperature ceramic compound Al5C3N belongs to the scarcely

Gamma bands in doubly odd rhenium and iridium nuclei
EPJ Web of Conferences, 2015 Structure of the |K ± 2| bands in doubly-odd nuclei belonging to the transitional deformation region at A∼190 is discussed. Relation of these quasi gamma-bands with the non-axial deformation of the parent two-quasiparticle configurations is studied ...

Long‐Range Polariton Canalization in a Graphene‐Nanoribbon–Covered MgTeMoO6 Metasurface
Nanophotonics, Volume 15, Issue 9, 13 May 2026.Simulated Re(Ez) field distributions at ω = 924 cm−1 for the graphene grating, MgTeMoO6 grating, the proposed hybrid structure, and the corresponding IFCs in (kx, ky) space are shown. Re(Ez) field maps in the x–y plane at ω = 924 cm−1 for Ef = 50, 70, 74, 76, 80, and 88 meV.

Optical Skyrmions Modulation Based on Polarization Helicity
Nanophotonics, Volume 15, Issue 9, 13 May 2026.The polarization helicity represents the global twisted property of the polarization state distribution, it can be used to modulate the spin skyrmion texture in the tight focusing of the radially polarized vortex light. By adjusting the polarization helicity of incident field, the Néel‐Bloch‐Néel transition of the spin skyrmion texture can be realized,

Beyond the Edge: Charge‐Transfer Excitons in Organic Donor‐Acceptor Cocrystals
Advanced Functional Materials, Volume 36, Issue 37, 7 May 2026.Complex excitonic landscapes in acene–perfluoroacene cocrystals are unveiled by polarization‐resolved optical spectroscopy and many‐body theory. This systematic study of a prototypical model system for weakly interacting donor–acceptor compounds challenges common views of charge‐transfer excitons, providing a refined conceptual framework for ...

Metasurfaces and Metadevices for Topological Electromagnetic Waves
Advanced Physics Research, Volume 5, Issue 5, May 2026.Optical topologies refer to diverse topological localized structures made by diverse parameters of light fields, such as vortices, skyrmions, and hopfions. This article navigates a direction of metasurface‐based integrated devices for generation, manipulation and detection of novel topologies of light, which would be a rapidly growing interdisciplinary
