Localization of edge state in acoustic topological insulators by curvature of space

New Journal of Physics, 2023
Topological insulators (TIs) with robust boundary states against perturbations and disorders have boosted intense research in classical systems. In general, two-dimensional (2D) TIs are designed on a flat surface with special boundary to manipulate the ...

Visualization of core and edge MHD instabilities in 2D using ECEI

EPJ Web of Conferences, 2012
MHD instabilities in the core and edge of the KSTAR plasmas have been visualized in 2D using an electron cyclotron emission imaging (ECEI) system with sufficient time and space resolutions for the study of the underlying dynamics.

MHD simulations of formation, sustainment and loss of quiescent H-mode in the all-tungsten ASDEX Upgrade

Nuclear Fusion, 2023
Periodic edge localized modes (ELMs) are the non-linear consequences of pressure-gradient-driven ballooning modes and current-driven peeling modes becoming unstable in the pedestal region of high confinement fusion plasmas.

Edge Localized Modes as New Bifurcation in Tokamaks

Physical Review Letters, 1996
A model of giant edge localized modes in tokamaks is developed. The theory of self-sustained turbulence of a current-diffusive ballooning mode is extended. A bifurcation from the H mode to a third state with magnetic braiding, the M mode, is found to occur if the pressure gradient reaches a critical value.

Localized modes in defective multilayer structures

, 2009
In this paper, the localized surface modes in a defective multilayer structure has been investigated. It is shown that the defective multilayer structures can support two different kind of localized modes depending on the position and the thickness of ...

Novel Edge Excitations of Two-dimensional Electron Liquid in a Magnetic Field

, 1993
We investigate the low-energy spectrum of excitations of a compressible electron liquid in a strong magnetic field. These excitations are localized at the periphery of the system.

Nonlinear localized gap modes in width-modulated Fibonacci lattices

Results 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
