Spectral Homogenization of the Radiative Transfer Equation via Low-Rank Tensor Train Decomposition

This paper demonstrates that the spectral complexity of the radiative transfer equation admits a finite effective rank via Young-measure homogenization, enabling highly accurate and efficient low-rank tensor train decompositions that significantly outperform traditional approximations like the correlated-k distribution across diverse molecular and atomic opacity sources.

Inelastic Constitutive Kolmogorov-Arnold Networks: A generalized framework for automated discovery of interpretable inelastic material models

This paper introduces Inelastic Constitutive Kolmogorov-Arnold Networks (iCKANs), a novel machine learning framework that automatically discovers interpretable, closed-form symbolic constitutive laws for both elastic and inelastic material behaviors by translating experimental data into potential functions, as demonstrated on viscoelastic polymers.

Electrodynamics of swift-electron momentum transfer to a large spherical nanoparticle

This paper establishes a robust electrodynamic framework using causal dielectric functions and full multipolar convergence to demonstrate that the net transverse linear momentum transferred from a swift electron to a large spherical nanoparticle is consistently attractive, thereby correcting previous theoretical predictions of repulsive behavior and highlighting the need for additional physical mechanisms to explain experimental observations.

Pole-Expansion of the T-Matrix Based on a Matrix-Valued AAA-Algorithm

This paper introduces a computationally efficient, open-source method that utilizes a matrix-valued adaptive Antoulas-Anderson (AAA) algorithm to represent the frequency-dependent T-matrix as a pole-expansion, thereby overcoming the high memory and computational costs of traditional discrete frequency sampling while preserving physical interpretability.
