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).

Nuclear Fusion, 2023 We study localized edge turbulence in the ASDEX Upgrade tokamak that appears if resonant magnetic perturbations (RMP) are applied to suppress edge localized modes (ELMs) in the high confinement mode.

Edge localized mode control with an edge resonant magnetic perturbation [PDF]
Physics of Plasmas, 2005 A low amplitude (δbr∕BT=1 part in 5000) edge resonant magnetic field perturbation with toroidal mode number n=3 and poloidal mode numbers between 8 and 15 has been used to suppress most large type I edge localized modes (ELMs) without degrading core plasma confinement. ELMs have been suppressed for periods of up to 8.6 energy confinement times when the

Custodial glide symmetry of quantum spin Hall edge modes in WTe$_2$ monolayer [PDF]
, 2018 A monolayer of WTe$_2$ has been shown to display quantum spin Hall (QSH) edge modes persisting up to 100~K in transport experiments. Based on density-functional theory calculations and symmetry-based model building including the role of correlations and ...

Topological Corner Modes in Graphene-Coated Nanowire Waveguide
Applied Sciences, 2020 We study the plasmonic second-order topological modes in nanowire waveguides which are covered by monolayer graphene. The waveguide arrays are arranged in the kagome lattice. In a triangle-shaped lattice, the topological modes are localized at the corner

Topological Valley Currents in Gapped Dirac Materials [PDF]
, 2014 Gapped 2D Dirac materials, in which inversion symmetry is broken by a gap-opening perturbation, feature a unique valley transport regime. The system ground state hosts dissipationless persistent valley currents existing even when topologically protected ...

Homogenized description of defect modes in periodic structures with localized defects [PDF]
, 2014 A spatially localized initial condition for an energy-conserving wave equation with periodic coefficients disperses (spatially spreads) and decays in amplitude as time advances. This dispersion is associated with the continuous spectrum of the underlying

Edge states and the η invariant
Physics Letters B, 2023 We propose a relation between the η invariant on a manifold with boundary, the η invariants of edge states, and the η invariant in an infinite volume limit. With the example of planar fermions with bag and chiral bag boundary conditions we show that this

Near-field scanning optical microscopy of photonic crystal nanocavities [PDF]
, 2003 Near-field scanning optical microscopy was used to observe high-resolution images of confined modes and photonic bands of planar photonic crystal (PPC) nanocavities fabricated in active InGaAsP material. We have observed the smallest optical cavity modes,

Experimental observation of edge states in SSH-Stub photonic lattices
Physical Review Research, 2022 We reveal unconventional edge states in a one-dimensional Stub lattice of coupled waveguides with staggered hoppings. The edge states appear for the same values of hoppings as topological edge states in the Su-Schrieffer-Heeger model. They have different
