One-dimensional relativistic hydrogen-like atom in Dirac materials: Energy spectra and supercritical states
S. Z. Rakhmanov, K. P. Matchonov, A. K. Rakhimov +1
We consider a model of 1D relativistic hydrogen-like atom, formed by a Coulomb impurity in graphene nanoribbon. Describing the electron motion in terms of the one-dimensional Dirac…

Optical high harmonic generation in Dirac materials
S. Rakhmanov, K. Matchonov, H. Yusupov +2
We study high-order harmonic generation by optically driven one- and two-dimensional hydrogenlike atoms formed by Coulomb imurities in graphene. The time-dependent Dirac equations…
