A new helical InSeI polymorph: crystal structure and polarized Raman spectroscopy study

This study reports the crystal structure of a new helical InSeI polymorph and utilizes polarized Raman spectroscopy to map its lattice dynamics and chain orientation, revealing that despite its helical structure, the material lacks chiral phonons.

Enhancement of topological magnon-driven spin currents through local edge strain in CrI3_3 nanoribbons

This study demonstrates that applying approximately 3% tensile edge strain to zigzag CrI3_3 nanoribbons significantly enhances topological magnon-driven spin currents and their decay lengths by inducing strongly localized edge states, thereby establishing straintronics as a viable method for controlling topological magnons in two-dimensional magnetic materials.

Ultrafast ghost Hall states in a 2d altermagnet

This paper demonstrates that two-dimensional altermagnets, exemplified by Cr2_2SO, enable the ultrafast control of spin and valley degrees of freedom via linearly polarized femtosecond laser pulses, facilitating nearly 100% spin-polarized valley currents and a novel "ghost Hall" effect where spin and charge currents become orthogonal without traditional Hall physics.

Strain-Induced Curvature in Monolayer Graphene: Effects on Electronic Structure, Phonon Dynamics, and Lattice Thermal Conductivity

This study demonstrates that applying x-y strain to monolayer graphene induces topological curvature that energetically stabilizes the system, modifies its electronic structure to create promising features for thermoelectrics, and reduces lattice thermal conductivity by enhancing phonon scattering through the transition of flexural acoustic modes from quadratic to linear dispersion.

Giant Domain-Wall Hall Magnetoresistance in Magnetic Topological Semimetal

This paper reports the discovery and theoretical verification of a giant longitudinal domain-wall Hall magnetoresistance in the magnetic Weyl semimetal Co3Sn2S2, which arises from an electric field distribution induced by the transverse giant anomalous Hall effect and offers potential for advanced multi-resistance-state modulation.

Electron localization, charge redistribution, and emergence of topological states at graphite junctions

Using a charge self-consistent tight-binding method, this study reveals that junctions between Bernal and rhombohedral graphite half-crystals universally host localized electronic states, with most configurations involving rhombohedral stacking supporting flat bands that suggest the emergence of strongly correlated and topological phenomena.

Semiclassical theory of frequency dependent linear magneto-optical transport in Weyl semimetals

This paper develops a semiclassical Boltzmann theory to demonstrate how frequency-dependent magneto-optical transport in Weyl semimetals is governed by the complex interplay of orbital magnetic moments, cone tilt, and intervalley scattering, revealing distinct regimes where strong scattering can suppress the chiral anomaly and where tilt orientation dictates the symmetry and sign of the longitudinal magneto-optical conductivity.

Loop-dependent entangling holonomies in localized topological quartets

This paper demonstrates that spectrally isolated topological quartets in localized settings can acquire loop holonomies that generate non-local, entangling quantum gates despite preserving a local two-qubit description at each parameter point, a phenomenon undetectable by standard topological diagnostics but revealed by measuring the distance of the holonomy to the local subgroup.
