Integrated photonic multigrid solver for partial differential equations

This paper presents a mixed-precision integrated photonic multigrid framework that offloads computationally intensive smoothing operations to low-latency optical matrix-vector multipliers, achieving high-accuracy solutions for partial differential equations while significantly reducing digital computational costs and offering a promising path for post-Moore's law computing.

A model for the decay of TKE in the CBL from the time evolution of the length and velocity scales: application in a Eulerian dispersion model

This paper proposes a simplified, non-differential model for predicting the decay of turbulent kinetic energy and deriving height-dependent eddy diffusivities in the convective boundary layer by tracking the time evolution of characteristic velocity and length scales, demonstrating that this approach outperforms height-independent parameterizations in sheared scenarios when incorporated into Eulerian dispersion models.

Atomistic dynamics of early oxidation of Si upon ultra-short pulsed laser heating

This study combines reactive molecular dynamics simulations with experimental validation to demonstrate that the early oxidation of silicon under ultra-short pulsed laser heating is governed by a transition from negligible growth below the melting point to rapid, diffusion-controlled oxide formation within the transient molten silicon layer.

Well-Posedness Diagnostics and Staged Numerical Solution of MHD Buoyant Flow over a Bi-Axially Stretching Surface with Cattaneo--Christov Thermal Relaxation

This paper presents a staged numerical solution and analytical admissibility criteria for magnetohydrodynamic buoyant flow over a bi-axially stretching surface with Cattaneo–Christov thermal relaxation, addressing the regular singular point induced by supercritical relaxation and demonstrating that elevated Hartmann and Prandtl numbers significantly constrain the physically realizable parameter domain.

Quantum Illumination for Stealth Target Detection: A Discrete-Qubit Toy Model on PKTron and IBM Quantum Hardware

This study demonstrates that a discrete-qubit toy model implemented on PKTron and IBM Quantum hardware fails to reproduce the theoretical advantage of quantum illumination for stealth target detection, showing instead that classically correlated probes outperform entangled ones under identical loss and noise conditions, thereby confirming that the purported quantum advantage is specific to continuous-variable Gaussian states rather than simple discrete correlations.
