The dispersion law for electrons has been derived by the Green's function method using the Anderson periodic model, which has been proposed to describe the electron subsystem in carbon nanotubes and graphene with impurities. The combined dynamics of electrons and an electromagnetic field has been considered in the low-temperature limit, and the effective equation describing the propagation of ultrashort optical pulses has been obtained. The solutions to this equation as functions of the parameters of the problem have been presented. © 2010 Pleiades Publishing, Ltd.

The effect of an ac electric field on the conductance of a system of single-wall semiconductor-type carbon nanotubes placed in a dc electric field is considered. The strength vectors of dc and ac electric fields are directed along the nanotube axis. The electronic system of carbon nanotubes is considered in the context of the Boltzmann kinetic equation in the relaxation-time approximation. The dependence of the current density in the system on the characteristics of applied fields is studied. The effect of absolute negative conductance is detected. © 2010 Pleiades Publishing, Ltd.

Propagation of a monochromatic laser beam in an array of carbon semiconductor nanotubes is considered. Initial distribution of the field intensity in the beam incident on the system is chosen in the form of a super-Gaussian profile in the plane perpendicular to the wave vector. The electromagnetic field of laser radiation in the nanotube array is described semiclassically by the Maxwell equations. In the approximation of slowly varying amplitudes and phases, the effective equation is derived and solved numerically that allows the intensity distribution of the beam field in the system to be determined. The phenomenon of laser beam self-focusing onto a waist region with increased field intensity is revealed. Dependences of the characteristics of the waist region on the amplitude and frequency of the laser radiation field incident on the system are obtained. © 2012 Springer Science+Business Media, Inc.

The effect of quantizing electric field on plasma oscillations of two-dimensional electron gas in a system with a periodic potential has been theoretically investigated. The coupled-plasmon spectrum ω(q) is calculated for high temperatures (Δ < T, where Δ is the conduction miniband width and T is temperature in energy units). The calculations are based on the quantum theory of plasma oscillations in the random-phase approximation, with allowance for the umklapp processes. © 2010 Allerton Press, Inc.

The problem of ultra-short optical pulse behavior in a system of carbon nanotubes with an applied magnetic field parallel to the nanotube axis was considered. The electromagnetic field was explored using the Maxwell equations. The electronic system of the carbon nanotubes was a quantum system and was mechan- ically investigated for the case of low temperatures. The distributional pattern of the ultra short pulses and their collision were established by means of numerical modeling. © Allerton Press, Inc., 2011.

The generation of high harmonics of current density in a superlattice based on graphene on a striped substrate is considered under the influence of static and alternating electric fields polarized along the superlattice axis. The areas of system parameter values are revealed for the first four harmonics, the amplitude of each of which surpasses the other three. © Allerton Press, Inc., 2012.

In this study we investigate the Zitterbewegunq (ZB) (jitter motion) effect in a thin film formed by graphene grown on a boron nitride substrate in the presence of a terahertz pump pulse, where the conduction electrons are described on the basis of the long-wavelength effective Hamiltonian in the case of low temperatures. An analytical expression is obtained which describes the current induced by the motion of the wave packet of electrons. The dipole radiation is calculated. © 2013 Springer Science+Business Media New York.

The wave equation for two ultrashort optical pulses propagating in metallic carbon nanotubes is analyzed. The behavior of electromagnetic pulses during a collision is examined as a function of their initial amplitudes and velocities. In the interaction of pulses of different amplitudes, absorption of the pulse with the smaller amplitude is observed. © 2015, Springer Science+Business Media New York.

The propagation of a variable electromagnetic field in arrays of "zigzag" carbon nanotubes at low temperatures is considered. The electronic system of carbon nanotubes is analyzed using the Hamilton formalism with ignoring interactions with the phonon subsystem because the electromagnetic field pulse is extremely short. An effective equation for the amplitude of the electromagnetic field vector-potential was obtained. Solutions-analogues of solitons were revealed; these solutions corresponded to solitons for the cosine electronic subsystem dispersion law. The dependences of the nonlinear solutions obtained on problem parameters were analyzed. © Pleiades Publishing, Ltd., 2010.
