Complete particle physics from an exactly solvable 21-state vacuum: 27 Standard Model predictions with zero free parameters and quantum hardware validation

This paper proposes an exactly solvable 21-state vacuum model derived from a 6-dimensional hypercube Hamiltonian that, without any free parameters, predicts 27 Standard Model observables with high precision and validates its results on IBM quantum hardware while offering two new falsifiable Beyond-the-Standard-Model predictions.

Upconversion luminescence and photothermal properties of the NaGdF4 :Er3+ /Yb3+/Al3+ nanoparticles in the hybrid films

This study demonstrates that fabricating hybrid films combining NaGdF4:Er3+/Yb3+/Al3+ upconversion nanoparticles with photonic crystals, silver nanoparticles, and either gold nanorods or single-walled carbon nanotubes enhances photothermal conversion and absolute sensitivity through multiphysics coupling, with the gold nanorod-based composite exhibiting the optimal balance of upconversion luminescence and photothermal performance.

Diffraction Characteristics of Asymmetric Apodized Circular Apertures in the Presence of Spherical Aberrations

This study investigates the impact of primary, secondary, and tertiary spherical aberrations on asymmetrically apodized circular apertures using scalar Fourier–Bessel theory, revealing that while primary aberration causes the most severe image degradation, the Blackman filter offers the best overall performance by maximizing Strehl ratios and sidelobe suppression, whereas the Connes filter provides superior spatial resolution.

Long-Range Electrostatics and Born Effective Charges from Invariant Moment Tensor Potentials with Latent Ewald Summation (MTP-LES)

This paper introduces MTP-LES, a machine-learning interatomic potential that integrates latent Ewald summation with rotationally invariant Moment Tensor Potentials to accurately model long-range electrostatics and Born effective charges in polar materials without explicit charge supervision, achieving performance comparable to graph-based baselines with minimal computational overhead.

Analytical Investigation of Carreau–Yasuda Fluid Flow in a Ciliated Channel

This study employs a regular perturbation technique under lubrication approximation to analytically investigate how Carreau–Yasuda fluid properties and cilia characteristics influence the flow dynamics, pressure distribution, and heat transfer in a two-dimensional ciliated channel, revealing that the model's shear-thinning behavior significantly modulates trapping-bolus formation and thermal performance compared to simpler fluid models.

Comparative Analysis of Bidirectional and Hybrid Pumping Schemes for Pre-Amplifier EDFAs: ASE-Induced Gain Saturation Dynamics

This paper presents a numerical study using a two-level rate equation model to demonstrate that while a 20-meter EDFA with 1480 nm forward pumping yields optimum gain, a hybrid pumping scheme outperforms bidirectional configurations for fiber lengths exceeding 15 meters due to superior management of ASE-induced gain saturation, thereby providing practical guidelines for optimizing pre-amplifier EDFA designs.
