Nonlinear Elasticity at the Damage Threshold of Semiconductor Nanocrystals

This study investigates the nonlinear photoacoustic response of indium phosphide nanocrystals on silicon nanotip arrays, revealing that high-fluence laser excitation induces strain-driven nonlinear elasticity and frequency mixing, which are modeled by an extended Hooke's law and linked to oxidation effects, thereby advancing the understanding of mechanical limits and optomechanical control in semiconductor nanostructures.

Global magnetic phase diagram and multiple unconventional magnets in NiAs-type compounds

This study establishes a global magnetic phase diagram for NiAs-type compounds using classical modeling and DFT calculations to identify new gg-wave altermagnetic and ff-wave odd-parity magnetic states, revealing that interlayer coupling drives a unique mixed-parity state in CrSe and CrTe1−x_{1-x}Sex_x and offering strategies to engineer unconventional magnets via doping or strain.

Can MACE Potentials Accurately Describe Magnetism and Phase Stability in Fe-Ni Alloys? A Systematic Benchmark

This study demonstrates that a system-specific MACE potential trained on spin-polarized DFT data for disordered Fe-Ni structures significantly outperforms existing foundation models in predicting structural, elastic, and finite-temperature properties, though it still struggles to accurately capture magnetic collapse effects governing the bcc-to-hcp phase transition.

Symmetry-Selective Topological Magnon Engineering by Phonon Angular Momentum

This paper demonstrates that coherently driven circular or elliptical phonons, which carry finite phonon angular momentum, can selectively engineer and tune topological magnon phases in materials like monolayer CrI3_3 by inducing chiral interactions that open gaps at Dirac points, whereas linearly polarized phonons leave the spectrum unchanged.

Electron-beam induced methane decomposition for in-situ carbon doping of hexagonal boron nitride

This paper demonstrates a method for achieving nanoscale-precise, in-situ carbon doping of hexagonal boron nitride by using electron-beam irradiation in a methane atmosphere to simultaneously generate vacancies and decompose methane, resulting in the formation of sub-nanometer carbon-rich patches with modified electronic environments.

Ultrafast dynamics of excitons in black phosphorus

By combining time- and angle-resolved photoemission spectroscopy with a quantum-kinetic theoretical framework, this study reveals that phonon-mediated intravalley scattering into dark excitons is the fundamental mechanism limiting coherent exciton dynamics in black phosphorus.

Manipulating Spin-Lattice Coupling in Layered Magnetic Topological Insulator Heterostructure $via$ Interface Engineering

This study demonstrates that interface engineering in a van der Waals heterostructure of the topological insulator Bi2_2Te3_3 and the antiferromagnet FePS3_3 induces spin-phonon coupling and modifies the magnetic ordering temperature, offering a pathway for controlling magneto-elastic modes in surface code spin logic devices.
