Edge mode locality in perturbed symmetry protected topological order [PDF]
SciPost Physics, 2019 Spin chains with symmetry-protected edge zero modes can be seen as prototypical systems for exploring topological signatures in quantum systems. These are useful for robustly encoding quantum information. However in an experimental realization of such

Multi-scale Interaction Mechanism for Edge-Localized-Mode Suppression in the Tokamak Edge [PDF]
Nature CommunicationsA central challenge in fusion energy is reconciling the high-confinement mode required for reactor performance with the intense intermittent relaxation events it produces, known as edge-localized modes.

Poloidal localization of the explosive onset of edge localized modes
Nuclear Fusion, 2023 In ASDEX Upgrade lower single null H-mode plasmas, the onset of the explosive phase of Edge Localized Modes (ELMs) is poloidally localized in the X-point/outer strike point (X/OSP) region. From this location, ELMs develop on average towards the low-field

Electron temperature fluctuation levels of the quasi-coherent mode across the plasma radius [PDF]
EPJ Web of Conferences, 2023 EDA H-mode is an ELM-free regime in which the edge quasi-coherent mode (QCM) replaces the ELMs. The estimated location of the quasi-coherent mode is in a partly optically thin region of steep gradients localized between ρpol = 0.96 -1.

The Effect of Edge Mode on Mass Sensing for Strained Graphene Resonators
Micromachines, 2021 Edge mode could disturb the ultra-subtle mass detection for graphene resonators. Herein, classical molecular dynamics simulations are performed to investigate the effect of edge mode on mass sensing for a doubly clamped strained graphene resonator ...

Induced microwave scattering in the ITER edge transport barrier at ECRH and possibility of its modeling at ASDEX-Upgrade [PDF]
EPJ Web of Conferences, 2023 The induced scattering parametric decay instability of O-mode polarized microwaves leading to excitation of lower hybrid or electron plasma waves localized within a tokamak edge transport barrier is investigated.

Automatic identification of edge localized modes in the DIII-D tokamak
APL Machine Learning, 2023 Fusion power production in tokamaks uses discharge configurations that risk producing strong type I edge localized modes. The largest of these modes will likely increase impurities in the plasma and potentially damage plasma facing components, such as ...

Kink–ballooning mode in circular tokamak plasma
AIP Advances, 2022 Peeling–ballooning modes, which are driven by gradients of parallel current and pressure in the pedestal, are widely accepted as the instability triggering large Edge Localized Modes (ELMs).
