Below are the latest papers in computational physics, curated to keep you at the forefront of this rapidly evolving discipline.
This paper introduces a computationally efficient beam-membrane biomechanical model of vocal folds that incorporates muscle-driven posturing and glottal conformation to predict voice production dynamics and investigate voice disorders, offering a practical alternative to expensive high-fidelity simulations.
This paper introduces CAVIAR, an electron ptychography framework that achieves sub-Angstrom resolution to reveal spatial correlations in atomic vibrations and accurately determine phonon frequencies from nanoscale volumes, offering a unique tool for studying atom dynamics and developing phonon-based technologies.
This study identifies that the underestimation of the Curie temperature in ferroelectric PbTiO primarily arises from limitations in exchange-correlation functionals rather than machine learning force field inaccuracies, revealing that apparent improvements from short-range models are fortuitous error cancellations while accurate predictions require explicit long-range interactions and improved functionals.
This paper introduces an extensible, open-source SHG Computational Toolkit Suite designed to overcome the limitations of existing analytical models and inaccessible experimental data by providing a coordinated collection of well-documented numerical tools for studying complex, thermally coupled second harmonic generation scenarios.
This paper introduces a Physically Constrained Ensemble Gaussian Process (pc-EGP) framework that integrates physical consistency penalties and ensemble learning to accurately model expensive, heteroskedastic quantum simulations, demonstrating superior performance in predicting critical parameters for the Bose-Hubbard model and optimizing chemical environments for superfluidity compared to conventional methods.
This paper introduces LAPG, a least-action-principle-guided diffusion framework that enhances physical consistency in generative models during inference by combining a conditional score-based model with an action-derived variational prior, thereby enabling reliable extrapolation across time, parameters, and geometries for various physical systems without relying solely on training-time constraints.
This paper demonstrates that an agentic large language model, guided by domain experts through a strict two-stage translation and rigorous validation process, successfully ported the 74,000-line Fortran FESOM2 ocean model to C++/Kokkos while preserving its physics and achieving significant performance gains on GPUs.
This paper introduces a novel framework for constructing real-time, structure-preserving neural surrogates for partial differential equations by integrating mixed finite element spaces with Gaussian process regression to enable tractable uncertainty quantification and closed-form posterior error bounds.
This paper introduces a hybrid deep-learning framework that uses a Multi-Scale Convolutional Neural Network to dynamically parameterize a Probabilistic Cellular Automata model in JAX, significantly improving wildfire spread prediction accuracy on large-scale US fires by capturing complex environmental interactions while maintaining physical interpretability.
This study demonstrates that while microstructural heterogeneity in grain geometry has a modest effect, a broad distribution of grain-boundary viscosities can suppress and broaden the characteristic Debye-like peak of elastically accommodated grain-boundary sliding into a weak background, thereby explaining the absence of a pronounced peak in dry olivine experiments without negating the mechanism's relevance to upper-mantle seismic attenuation.
