Anomalous magnetotransport in a non-collinear correlated kagome ferromagnet MgMn6Sn6

This study characterizes the room-temperature non-collinear kagome ferromagnet MgMn6Sn6 through neutron diffraction and transport measurements, revealing its complex magnetic structure, large intrinsic and anisotropic extrinsic anomalous Hall effects, and strong electron correlations, thereby establishing it as a promising platform for investigating the interplay between topology, magnetism, and correlations.

Anisotropic Defect Diffusion in Layered CsPbBrx_\mathrm{x}I3−x_\mathrm{3-x} Perovskites

Large-scale molecular dynamics simulations reveal that layered ordering of bromine and iodine anions in CsPbBrx_\mathrm{x}I3−x_\mathrm{3-x} perovskites induces strongly anisotropic defect diffusion, where migration is facile along the layers but suppressed across them due to directional lattice strain and specific bonding configurations.

Gate-modulated reflectance spectroscopy for detecting excitonic species in two-dimensional semiconductors

The authors developed a highly sensitive, gate-modulated reflection spectroscopy technique that successfully enables the detection of excitonic states in two-dimensional transition metal dichalcogenides from cryogenic to room temperatures, thereby offering a superior alternative to conventional reflection methods for investigating exciton physics in these materials and their heterostructures.

Melting of Charge Density Waves in Low Dimensions

This article experimentally demonstrates and elucidates the continuous hexatic melting mechanism of incommensurate charge density waves in low-dimensional materials and reveals a progression from elastic deformations to the nucleation of topological defects through the observation of azimuthal peak broadening, wave vector contraction, and intensity reduction.

Tuning charge-transport properties and magnetic order in metallic EuTiO3−δ_{3-\delta}

This study demonstrates that oxygen-vacancy doping in metallic EuTiO3−δ_{3-\delta} induces a distinct phase diagram compared to cation substitution, driving a transition from antiferromagnetic to ferromagnetic order with a Curie temperature of approximately 11 K, a finding supported by transport measurements, density functional theory, and diffuse scattering data.

A Scalable Translationally Invariant Variational Theory of Ab Initio Polarons

This paper introduces a scalable, translationally invariant variational theory for ab initio polarons that combines momentum-projected wavefunctions with low-rank kernel factorization to accurately model carrier behavior across coupling regimes in the thermodynamic limit, revealing significant biases in existing diagrammatic Monte Carlo results for strong-coupling hole polarons in LiF.

Polarizable atomic multipoles for learning long-range electrostatics

This paper introduces a semi-local framework that integrates polarizable atomic multipoles with non-self-consistent linear response to enable machine learning interatomic potentials to accurately model long-range electrostatics and predict polarization-sensitive observables like Born effective charges and infrared spectra across diverse ionic and polar systems.
