High-harmonic spectroscopy of mobility edges in one-dimensional quasicrystals
H. K. Avetissian, B. R. Avchyan, A. Brown +1
Quasicrystals occupy a unique position between periodic and disordered systems, where localization phenomena such as Anderson transitions and mobility edges can emerge even in the…
High-order harmonic generation in three-dimensional Weyl semimetals
H. K. Avetissian, V. N. Avetisyan, B. R. Avchyan +1
In this paper, the nonlinear interaction of Weyl semimetal (WSM) with a strong driving electromagnetic wave-field is investigated. In the scope of the structure-gauge invariant low…
