  • Optimal conditions for detecting optical dichroism at the nanoscale by electron energy-loss spectroscopy

    Author(s): Marek Zálešák, Martin Ošmera, Martin Hrtoň, and Andrea Konečná Probing chirality below the diffraction limit is vital for understanding biological processes and designing chiral nanostructures. While orbital angular momentum (OAM)-resolved electron energy-loss spectroscopy (EELS) is a promising candidate for detecting nanoscale circular dichroism, experimental results remain elusive. This study presents a theoretical framework for understanding...

  • Signatures of bulk g-wave altermagnetism in optically excited $α\text{−}\mathrm{MnTe}$

    Author(s): Luca Felipe Haag, Marius Weber, Kai Leckron, Libor Šmejkal, Jairo Sinova, and Hans Christian Schneider Excitation by linearly polarized femtosecond laser pulses provides a direct view into the altermagnetic structure via the non-equilibrium spin-polarized electronic populations in a band structure whose symmetry encodes the underlying bulk g-wave order. The spin-dependent electronic response calculated in this paper can be accessed...

  • Thermodynamics and phase stability of the AlTiCrMoW high-entropy alloy simulated using machine-learned interatomic potentials

    Author(s): Joseph E. Arnold, Christopher D. Woodgate, Roohollah Hafizi, Matthew J. Harris, Alessandro Mottura, Gonzalo García Fuentes, and Beñat Gurrutxaga-Lerma High-entropy alloys (HEAs) possess exceptional mechanical properties and thermal stability, yet their vast compositional space and complex atomic arrangements present significant challenges for property prediction and design. To overcome this, we have trained a machine-learned interatomic...

  • Enhancement of topological magnon-driven spin currents through local edge strain in ${\mathrm{CrI}}_{3}$ nanoribbons

    Author(s): David Sanz Ruiz and David Soriano This work describes topological magnon transport in zigzag ${\mathrm{CrI}}_{3}$ nanoribbons in the presence of edge strain. Exchange coupling terms under strain are obtained from first-principles calculations and the topological properties are introduced via second-neighbor Dzyaloshinskii-Moriya int… [Phys. Rev.

  • Collinear spin density wave state in distorted square-lattice ${\mathrm{GdNiSn}}_{4}$

    Author(s): Charles C. Tam, Sarah Schwarz, Xin Zhang, Sudipta Chatterjee, Scott B. Lee, Rebecca Scatena, Leslie M. Schoop, and Stephen D. Wilson We characterize the magnetic ground state of the newly synthesized lanthanide intermetallic ${\mathrm{GdNiSn}}_{4}$ via resonant elastic x-ray scattering measurements. This compound forms distorted square nets of Gd that initially order magnetically below 23 K, followed by a lower-temperature transi… ...

  • Stoichiometry dependent properties of cerium hydride: An active learning developed interatomic potential study

    Author(s): Brenden W. Hamilton, Travis E. Jones, Timothy C. Germann, and Benjamin T. Nebgen Cerium hydride has a variety of interesting properties, including a known lattice contraction and densification with increasing hydrogen content. However, precise stoichiometric control is not experimentally straightforward and ab initio approaches are not computationally feasible for many propertie… [Phys. Rev.

  • Nanomechanics of liquid-quench-derived nanoporous amorphous carbon using ReaxFF molecular dynamics

    Author(s): M. A. Busaidi, M. Kowalik, A. C. T. van Duin, and T. Dumitrică Using liquid-quench reactive force field ReaxFF molecular dynamics, we revisit how changes within the method parameter space—annealing time, annealing temperature, and number of atoms—influence the nanostructure of ${sp}^{2}$-dominated amorphous carbon at 1 g/cm³ mass density. Initially, the degree … [Phys. Rev. Materials 10, 073604] Published Mon Jul 20, 2026
