Effect of hybrid field coupling in nanostructured surfaces on anisotropic signal detection in nanoscale infrared spectroscopic imaging methods

This paper investigates the effect of hybrid field coupling on anisotropic signal detection in nanoscale infrared spectroscopic imaging by comparing PiF-IR hyperspectra of aligned perylene Langmuir-Blodgett monolayers on nanostructured versus planar gold substrates and interpreting the results using quantum chemical calculations of oriented vibrational oscillators.

Smoothed truncated Coulomb potential for periodic Gaussian-basis Hartree--Fock exchange

This paper introduces the smoothed truncated Coulomb (sTC) potential, a systematically improvable approximation that enables efficient and accurate periodic Hartree--Fock exchange calculations with Gaussian basis sets for both pseudopotential and all-electron systems by smoothing the truncation boundary to facilitate a dual-space integral evaluation algorithm.

Multi-image Overlap Stitching and Automatic Image Construction for Coherent X-ray Imaging

This paper introduces MOSAICX, an automated workflow that efficiently stitches hundreds of partially overlapping direct-space coherent X-ray images into a single large-area composite, enabling the comprehensive visualization and analysis of magnetic-domain structures beyond the field of view of individual measurements.

XUV Transmission Spectroscopy Using a Tabletop High-Harmonic Source

This study demonstrates the construction of an argon-based tabletop high-harmonic generation source capable of producing XUV pulses up to 70.6 eV and validates its utility for characterizing thin-film transmission and correlating surface oxidation states with XUV absorption properties.

Optical-Phonon-Enabled Large Lattice Thermal Conductivity Anisotropy in Hexagonal Perovskites CsBX3BX_3 (BB = Mg, Cd; XX = Cl, Br, I)

This study reveals that hexagonal perovskites CsBX3_3 exhibit remarkably large lattice thermal conductivity anisotropy despite near-isotropic elasticity, a phenomenon driven by efficient out-of-plane heat transport via medium-frequency optical phonons rather than the conventional acoustic phonon mechanism.

GW and Bethe-Salpeter Theory for Molecular Polaritons, Quasiparticles, and Excitons

This paper develops a QED-GWGW framework for molecular polaritons using the dipole-gauge Pauli-Fierz Hamiltonian to quantify how optical cavities modify quasiparticle energies and excitonic properties, revealing that cavity-induced shifts are predominantly driven by static dipole self-energy effects rather than resonant coupling, while highlighting the basis-set sensitivity of exciton-binding energies involving unbound anions.

Overcoming the Efficiency-Stability Trade-off in Spin-Orbit Torque Devices with Thermally Robust BCC NiW Alloys

This paper demonstrates that thermally robust BCC Ni30_{30}W70_{70} alloys overcome the efficiency-stability trade-off in spin-orbit torque devices by enabling ultra-low critical current switching and high thermal stability, thereby establishing a scalable platform for next-generation SOT-MRAM.

Separating perception from reasoning in vision-language models: a model-free render ceiling for crystal structures

This paper introduces the "render ceiling," a model-free benchmarking method that uses inverted camera rendering of known crystal structures to definitively separate visual perception errors from reasoning failures in vision-language models, revealing that many models struggle with geometric extraction rather than logical inference.
