Comparative Assessment of Thermal Transport Theories: Dual-Channel Mechanism Dictates Heat Transport in Ultralow-κ\kappa Materials

This study demonstrates that the Wigner transport equation (WTE) framework, which accounts for both particle-like and wave-like coherence channels alongside higher-order phonon scattering, successfully predicts the ultralow thermal conductivity of strongly anharmonic materials like TlAgSe and Cs2_2PbI2_2C2_2, resolving the limitations of conventional Green-Kubo and Boltzmann transport theories.

Dynamic Magnetic Pair-Density Function of a One-Dimensional Ferromagnet

This paper establishes the theoretical foundation for analyzing local spin dynamics in magnetic materials by deriving and validating the dynamic magnetic pair-density function (DymPDF) for a one-dimensional Heisenberg ferromagnet, demonstrating its ability to capture energy-dependent spin correlations and magnon-mode transitions through analytical derivation and SpinW simulations.

Unified Bonding Entropy Model for Kekulé Graphene Nanoflakes

This paper introduces a Unified Bonding Entropy Model that explains open-shell stabilization in Kekulé graphene nanoflakes through "Clar-number-invariant resonance-space expansion," demonstrating that increasing the number of accessible resonance configurations rather than the maximum Clar sextet count drives electron unpairing and correlates strongly with key electronic and structural properties.

A test drive for exchange-correlation functionals on noncollinear magnets: Mn3_3Ir, Mn3_3Ge, NiS2_2, and YMnO3_3

This study demonstrates that spin-current density-functional theory (SCDFT) functionals, specifically NCMSCAN and LFNCBR89-NCCS, successfully recover the experimental spin texture of the noncollinear magnet NiS2_2 at a computational cost comparable to standard semi-local approximations, outperforming traditional spin-DFT extensions in capturing noncollinear physics.

Strain-driven spin-flop transition and collapse of the giant magnon gap in the bilayer iridate Sr3_3Ir2_2O7_7

First-principles calculations reveal that biaxial compression in the bilayer iridate Sr3_3Ir2_2O7_7 collapses the interlayer exchange channel and giant magnon gap, driving a strain-induced spin-flop transition from a collinear cc-axis antiferromagnetic state to an in-plane ordered phase via a mechanism governed by Hund's exchange.

Chiral Phonons and Giant Anisotropic Photoresponse in Quasi-1D van der Waals Semiconductor ZrSnS3

This study characterizes the anisotropic lattice dynamics and chiral phonon behavior of the quasi-one-dimensional van der Waals semiconductor ZrSnS3_3 through combined experimental and theoretical analysis, while demonstrating its potential for polarization-sensitive optoelectronics via a nanowire device exhibiting giant anisotropic photoresponse.

Mechanistic Phase-Field Modelling of Woven-Domain Formation in Ferroelectric Material

This study employs a nondimensional phase-field model to demonstrate that slow cooling through the ferroelectric transition enables the kinetic selection of a three-dimensional woven domain topology in KTN:Li by facilitating the persistence and topological exchange of charge-associated precursor crossings, a mechanism that is suppressed under fast-cooling conditions.
