Tunable plasmon modes and topological transitions in single- and bilayer semi-Dirac materials
We investigate the plasmonic response of single- and bilayer semi-Dirac materials under the influence of a tunable parameter $δ$ that governs topological transitions via Dirac cone generation/merging and incorporating band inversion terms. For single-layer systems, we demonstrate that the emergence of Dirac cones leads to an enhanced plasmon frequency range and that the plasmonic spectrum exhibits strong anisotropy, especially for finite $δ$ and vanishing inversion terms. In the bilayer confi…

A Geometric Solution to the Isoperimetric Problem and its Quantitative Inequalities
This paper introduces a geometric solution to the classical isoperimetric problem by analysing the area efficiency of n-sided regular polygons through a novel apothem-hypotenuse ratio framework. A new formula is derived to quantify polygonal efficiency based on apothem, hypotenuse, and perimeter, demonstrating how regular polygons approach the optimal area-enclosing efficiency of the circle as the number of sides increases. The work further presents an original formula for area lost relative to…

Photonic Contributions to the Apparent Seebeck Coefficient of Plasmonic Metals
Photo-induced charge transport in plasmonic metal nanostructures has garnered significant interest for applications in sensing and power conversion, yet the underlying mechanisms remain debated. Here, we report spatially correlated photovoltage generation in photonically engineered Au nanowires illuminated by focused, milliwatt-level laser excitation. Plasmonic nanodisk antennas placed adjacent to the nanowires created local variations in the photonic environment, resulting in clearly defined r…

Simulation of Shattered Pellet Injections with Plasmoid Drifts in ASDEX Upgrade and ITER
Pellet injection is an important means to fuel and control discharges and mitigate disruptions in reactor-scale fusion devices. To accurately assess the efficiency of these applications, it is necessary to account for the drift of the ablated material toward the low-field side. In this study, we have implemented a semi-analytical model for ablation cloud drifts in the numerical disruption modelling tool DREAM. We show that this model is capable of reproducing the density evolution in shattered …

Reconstruction-free magnetic control of DIII-D plasma with deep reinforcement learning
Precise control of plasma shape and position is essential for stable tokamak operation and achieving commercial fusion energy. Traditional control methods rely on equilibrium reconstruction and linearized models, limiting adaptability and real-time performance. Here,the first application of deep reinforcement learning (RL) for magnetic plasma control on the mid-size DIII-D tokamak is presented, demonstrating a nonlinear approach that improves robustness and flexibility across plasma scenarios. …

Embedding physical symmetries into machine-learned reduced plasma physics models via data augmentation
Machine learning is offering powerful new tools for the development and discovery of reduced models of nonlinear, multiscale plasma dynamics from the data of first-principles kinetic simulations. However, ensuring the physical consistency of such models requires embedding fundamental symmetries of plasma dynamics. In this work, we explore a symmetry-embedding strategy based on data augmentation, where symmetry-preserving transformations (e.g., Lorentz and Galilean boosts) are applied to simulat…
