Temperature-Dependent nonlinear optics from first-principles: Second-Harmonic Generation in few-layers MoS2_2

This paper presents a first-principles real-time approach incorporating finite-temperature electron-phonon effects to demonstrate that strong, crystal-momentum-dependent quasiparticle renormalization drives the nontrivial temperature dependence of second-harmonic generation in few-layer MoS2_2, thereby explaining the experimentally observed intensity increase in monolayers.

Hysteretic Coherence Collapse Across the First Order CDW Transition in 1T-TaS2

Using angle-resolved photoemission spectroscopy, this study reveals that the in-gap state in 1T-TaS2 undergoes an abrupt, hysteretic collapse and recovery across the first-order transition between commensurate and nearly commensurate charge density wave phases, providing direct spectroscopic evidence of the transition's first-order nature and its intimate link to electronic reconstruction.

Selective coupling of high-order phonons in La2-xSrxCuO4

Using resonant inelastic X-ray scattering, researchers discovered a novel regime of electron-phonon coupling in La2-xSrxCuO4 characterized by the selective excitation of even-order high-frequency phonons that vanish with doping, suggesting the presence of locally paired quasiparticles that deviate from the standard Franck-Condon picture.

Learning Metamaterial Eigenmodes with Wavelet-Encoded Fourier Neural Operators

This paper demonstrates that combining Fourier Neural Operators with wavelet-based input encodings enables the efficient, high-fidelity prediction of multiple elastic wave eigenmodes in arbitrary metamaterial geometries, accelerating design cycles by three orders of magnitude compared to traditional finite element analysis.

Atomistic modeling of molecular beam epitaxy growth of SrTiO3 and Sr2TiO4 thin films

This study employs first-principles calculations to reveal three key atomistic mechanisms—oxygen vacancy-induced diffusion acceleration, TiSr defect-promoted SrO island formation, and Ti insertion into SrO bilayers—that govern the molecular beam epitaxy growth of SrTiO3 and Sr2TiO4 thin films, offering critical insights for improving growth precision in metal oxide films.

Observation of multipartite spin entanglement in a cuprate chain

This study demonstrates that resonant inelastic X-ray scattering (RIXS) can directly extract Quantum Fisher Information from spin fluctuation spectra, enabling the experimental detection of at least 7-partite spin entanglement in the cuprate Sr2_2CuO3_3 that persists at elevated temperatures.
