Photogeneration and signatures of coherent phonons in time-resolved photoemission spectroscopy: First-principles time-dependent adiabatic GW approach

This paper presents a first-principles time-dependent adiabatic GW approach to simulate coherent phonon photogeneration and their signatures in time-resolved photoemission spectroscopy of monolayer MoS2, demonstrating that analyzing these modulations enables the extraction of state-resolved electron-phonon coupling strengths and clarifies the underlying generation mechanisms.

Single-orbital tight-binding model for chiral one-dimensional hybrid organic-inorganic lead halide perovskites

This paper introduces a symmetry-transparent single-orbital tight-binding model for chiral one-dimensional hybrid organic-inorganic lead halide perovskites that accurately reproduces band dispersions and spin splittings while distinguishing between accidental and symmetry-enforced degeneracies to facilitate the analysis of their electronic and spintronic properties.

Phase-shifted multicomponent spin-charge nematicity in an altermagnet

This paper reports the discovery of phase-shifted altermagnetic nematicity in Co0.25NbSe2, where spectroscopic imaging reveals that the dominant spin-sensitive component is shifted by one C3 sector relative to the charge component, establishing a new form of multicomponent electronic order driven by the interplay between altermagnetic symmetry and lattice pinning.

Surface Phase-Field-Crystal-Helfrich model for out-of-plane deformations in thin crystalline sheets with lattice mismatch

This paper presents an extended Surface Phase-Field-Crystal-Helfrich model that incorporates spatially varying lattice spacing to simulate lattice mismatch in thin crystalline sheets, validating the approach against classical theories to demonstrate how localized compressive stresses drive out-of-plane deformations.

Tracing boron diffusion into a textured silicon solar cell using electron beam induced current in a scanning transmission electron microscope

This paper presents a combined experimental and simulation framework using scanning transmission electron beam induced current (STEM-EBIC) to successfully trace and quantify boron dopant distributions beneath the pyramid-like textured surfaces of silicon solar cells, accounting for surface recombination effects to enable future measurements of weak electric fields.

Scaling active spaces in simulations of surface reactions through sample-based quantum diagonalization

This paper demonstrates the potential of sample-based quantum diagonalization (SQD) and its extended variant (Ext-SQD) to accurately model oxygen reduction reactions in lithium batteries by scaling active space simulations up to 32 orbitals on an IBM quantum processor, outperforming classical reference methods at larger scales.

The BPHZL renormalization of a planar quantum electrodynamics up to 2-loops and beyond

This paper demonstrates the ultraviolet and infrared finiteness of a parity-even, massless U(1)×U(1)U(1)\times U(1) quantum electrodynamics in three dimensions up to two loops and beyond by employing the BPHZL renormalization method combined with the Lowenstein-Zimmermann subtraction scheme to address infrared divergences arising from ultraviolet subtractions.

Growth of ultra-clean single crystals of RuO2

This paper reports the successful growth of ultra-clean RuO2 single crystals with diverse morphologies and exceptional purity (RRR up to 1200) using a necked crystal-growth tube and sublimation transport method, confirming their suitability as a candidate for altermagnetism while showing no magnetic ordering down to low temperatures.
