In this paper, we study the features of the evolution of an electromagnetic pulse in fractal structures. Different fractal structures were considered, with different symmetry and different generators. Based on the electron dispersion law for fractal

We study the features of the evolution of a pulse in a dielectric medium (crystal) with optical anisotropic properties taking into account pumping. The medium contains semiconductor carbon nanotubes of a fixed orientation directed at an angle to one

In this paper, we study the influence of acoustic and magnetic fields on the propagation of twodimensional light bullet in an array of carbon nanotubes. The acoustic field is taken into account in the framework of the gauge theory. A magnetic field i

The Zitterbewegung (ZB) effect in space-time described by the Lifshitz four-dimensional black hole metric is considered. The Lifshitz black hole is taken with the dynamic exponent z = 2 and the flat topology in the cross section. Zitterbewegung is ca

We consider the Zitterbewegung (ZB) effect induced in the AdS (anti-de Sitter) space-time by a cosmic string. Near the cosmic string, the effects of curvature play a dominant role. The ZB was calculated based on the Dirac equation in a curved space-t

We present a study of the propagation of three-dimensional (3D) bipolar electromagnetic ultrashort pulses in an inhomogeneous array of semiconductor carbon nanotubes (CNTs) in the presence of a control high-frequency (HF) electric field. The inhomoge
