Physical Review BAltermagnets are compensated magnets with unconventional $d$, $g$, and $i$-wave spin order in reciprocal space. So far the search for new altermagnetic candidates has been focused on materials in which the magnetic unit cell is identical to the non-magnetic one, i.e. magnetic structures with zero propagation vector.

New Journal of Physics, 2018 Charged defects are traditionally computed by adding (subtracting) electrons for negative (positive) impurities. When using periodic boundary conditions this results in artificially charged supercells that also require a compensating background charge of

Metasurface-driven full-space structured light for three-dimensional imaging
Nature Communications, 2022 3D depth sensing with structured light enables simultaneous imaging of multiple objects, but has limited field of view and low efficiency. Here, the authors demonstrate 3D imaging with scattered light from a metasurface composed of periodic supercells ...

Supercell Spectrum. Part II: A Semi-Objective Method for Radar Classification of Supercell Type
E-Journal of Severe Storms Meteorology, 2021 his paper describes a method for classifying supercells that relies partially upon a mixture of objective radar analysis and human analysis. The technique is used to ascertain the direction and distance of supercell precipitation core centroids from their updrafts.

Fractal identification of supercell storms [PDF]
Geophysical Research Letters, 2002 The most intense and violent form of convective storm is the supercell storm, usually associated with heavy rain, hail, and destructive gusty winds, downbursts, and tornadoes. Identifying a storm cell as a supercell storm is not easy. What is shown here, from radar data, is that when an ordinary, or multicell storm evolves towards the supercellular ...

Comparative Analysis on Dual Polarization Features of Two Severe Hail Supercells
应用气象学报, 2022 Using S-band dual-polarization weather radar data, sounding and ground meteorological observations, and disaster investigation reports, the similarity and difference of dual polarization parameters between Lixian and Zhangqiu supercells with hails above ...

Advanced Functional Materials, EarlyView.A previously unreported coordination motif stabilising single Fe atoms by indigo chelation and pyridyl coordination on Au(111) has been revealed. By using planar tritopic pyridyl linkers (TPyB), extended 2D porous networks of indigo3(TPyB)2Fe6 form. These networks can be crystalline or vitreous and offer an environment where individual coordination ...

Lithium Intercalation in the Anisotropic Van Der Waals Semiconductor CrSBr
Advanced Functional Materials, EarlyView.We report the lithium intercalation in the layered van der Waals crystal CrSBr, revealing strongly anisotropic ion‐migration dynamics. Optical and electrical characterization of exfoliated CrSBr shows lithium diffusion coefficients that differ by more than an order of magnitude along a‐ and b‐directions, consistent with molecular dynamics simulations ...
