Edge mode locality in perturbed symmetry protected topological order [PDF]

open access: yesSciPost 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

EDGE LOCALIZED MODES IN TOKAMAKS [PDF]

open access: yesFusion Science and Technology, 2015
As one increases the heating power in a tokamak beyond a threshold, the confinement undergoes a bifurcation, with a dramatic increase in the confinement time by a factor ˜2.

Dynamical signatures of topological order in the driven-dissipative Kitaev chain [PDF]

open access: yesSciPost Physics, 2019
We investigate the effects of dissipation and driving on topological order in superconducting nanowires. Rather than studying the non-equilibrium steady state, we propose a method to classify and detect dynamical signatures of topological order in ...

Multi-scale Interaction Mechanism for Edge-Localized-Mode Suppression in the Tokamak Edge [PDF]

open access: yesNature Communications
A 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

open access: yesNuclear 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

Prospects of core–edge integrated no-ELM and small-ELM scenarios for future fusion devices

open access: yesNuclear Materials and Energy, 2023
One of our grand challenges towards fusion energy is the achievement of a high-performance plasma core coupled to a boundary solution. The high confinement mode (H-mode) provides such a high-performance fusion core due to the build-up of an edge ...

Automatic identification of edge localized modes in the DIII-D tokamak

open access: yesAPL 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 ...

Nonlinear localized gap modes in width-modulated Fibonacci lattices

open access: yesResults in Physics, 2022
We address the properties of nonlinear localized gap modes supported by the width-modulated Fibonacci lattices, including their existence and stability. Linear system with the width-modulated Fibonacci lattices has multiple gaps. We find the existence of

The investigation of edge-localized modes on the Globus-M2 tokamak using Doppler backscattering

open access: yesNuclear Fusion, 2023
The first results of investigation of edge localized modes (ELMs) in the Globus-M2 tokamak using the Doppler backscattering method are presented in this paper. Specifically, ELMs that are initiated by sawtooth crashes in the H-mode are discussed.

Plasmoid-mediated reconnection during nonlinear peeling–ballooning edge-localized modes

open access: yesNuclear Fusion, 2023
Plasmoid-mediated reconnection is investigated for nonlinear peeling–ballooning edge-localized modes (P-B ELMs). The formation of current sheets and the transition to 3D current sheet instability is demonstrated through fully nonlinear resistive MHD ...
