DOI: 10.1002/ctpp.201700142
Abstract: Edge localized modes (ELMs) are repetitive instabilities driven by the large pressure gradients and current densities in the edge of H-mode plasmas. Type-I ELMs lead to a fast collapse of the H-mod ... read more here.

DOI: 10.1007/s10958-018-3877-y
Abstract: The spectral problem for an infinite periodic medium perturbed by a compact defect is considered. For a high contrast small ε-size periodicity and a finite size defect we consider the critical ε2-scaling for the contrast.… read more here.

DOI: 10.1103/physreve.97.032209
Abstract: This work investigates the effect of nonlinearities on topologically protected edge states in one- and two-dimensional phononic lattices. We first show that localized modes arise at the interface between two spring-mass chains that are inverted… read more here.

DOI: 10.1103/physrevlett.121.025002
Abstract: The acceleration of beam ions during edge localized modes (ELMs) in a tokamak is observed for the first time through direct measurements of fast-ion losses in low collisionality plasmas. The accelerated beam-ion population exhibits well-localized… read more here.

DOI: 10.1103/physrevlett.121.235001
Abstract: Prior to eruptive events such as edge localized modes (ELMs), quasicoherent fluctuations, referred to as pedestal modes, are observed in the edge of fusion devices. We report on the investigations of nonlinear coupling between these… read more here.

DOI: 10.1364/prj.6.000117
Abstract: We demonstrate terahertz (THz) frequency laser emission around 3.2 THz from localized modes in one-dimensional disordered grating systems. The disordered structures are patterned on top of the double-metal waveguide of a THz quantum cascade laser. Multiple… read more here.
