Safaa Mohammed Ridha Hussein Hussein, Muthana Alboedam and Vasiliy Gavrilov * Study the properties of conductivity in two-layer graphene using mathematical modeling *

Graphene is a two-dimensional allotropic form of carbon, with atoms combined into a hexagonal crystal lattice, forming a layer one atom thick. Graphene possessing exceptional optical, mechanical, physical and electrophysical properties. This article details some of the conductivity in graphene. The conductivity of the two-layer graphene was measured by special mathematical models, with conductivity dependent on the voltage at the gate at different temperatures. Conductivity is faced with a jump at zero temperature and a sharp, standard rise in properties at room temperature, as shown clearly in the resulting electronic spectrum.

Sergey Kharitonov, Safaa Hussein, Ann Frize and Nikolay Kazanskiy * Calculation of the band structure of an array of spherical quantum dots *

The article is dedicated to the calculation of the band structure of a linear array of quantum dots.

Mikhail Evseev, Eugene Bashkirov, Ali Othman and Anna Gorchakova-Zakatova * Entanglement in two-atom Jaynes-Cummings model with Kerr nonlinearity *

The entanglement of a quantum system consisting of two superconducting circuits interacting with one-mode quantum electromagnetic field of microwave coplanar cavity in the framework of two-atom Jaynes-Cummings model with the Kerr medium is studied, and the effect of the Kerr medium on that is examined. The result shows that for separable initial atomic states, the Kerr medium can control the entanglement dynamics of the qubits and enhances the amount of qubit-qubit entanglement. We can obtain the maximum entanglement between the atoms by strengthening the nonlinear interaction of the Kerr medium.

Maria Buzaeva, Irina Makarova and Vyacheslav Sergeyev * Dispersion systems with multi-walled carbon nanotubes in a polymer binder *

Physicochemical methods of analysis investigated the structure and properties initial and functionalized multi-walled carbon nanotubes. Studied the effect of the type and size of nanocarbon particles, their percentage, time ultrasonic dispersion on the stability of dispersed carbon systems nanotubes with acrylic monomers. For dispersion into a material matrix the most promising in technological properties are carbon nanotubes functionalized by grafting on the surface of polar carboxyl groups and forming a stable dispersed system with acrylic monomers.

Alexander Gorokhov * Coherent states and control of molecular dynamics *

The method of coherent states on dynamical Lie groups is used to describe the interaction of molecules with stuctured electromagnetic fields. The quantum control of the rotation and vibration of molecules is investigated. In the case of a symmetric top and for vibrations of a molecule with weak anharmonicity, interaction with an external dissipative environment is taken into account. Possible applications in photonics and quantum informatics are considered.

Hanh Hong Mai * The influence of precursor concentration on the crystallinity and morphology of ZnO nanorods grown on printed circuit board substrate *

In this work, the influence of precursor concentration on the surface morphologies, and the crystallinity of ZnO nanorods (NRs) grown on printed circuit board substrates (PCBs) is presented. It was shown that by implementing a galvanic cell structure in an aqueous solution of equimolar concentration of zinc nitrate hexahydrate (Zn[NO3]2·6H2O) and hexamethylenetetramine (C6H12N4), ZnO NRs can directly grow on the PCBs substrate without the assistance of a seed layer. It has been shown that the vertical growth and the crystallinity of the ZnO NRs can also be significantly improved by increasing the equimolar precursor concentrations. The morphologies of the ZnO nanorods were investigated by scanning electron microscope (SEM) and X-ray diffraction (XRD). The crystallinity properties were characterized by Raman spectroscopy and photoluminescence (PL) spectroscopy.

Shostka Vladimir, Shostka Nataliya, Vershitsky Vladislav and Khalilov Server * Structural features of the near-surface layers of highly dilute aqueous solutions *

Currently, particular importance is paid to highly dilute aqueous solutions, due to the fact that not only the presence of clusters, but also more complex structures have been found in them. However, the phenomenon of the emergence of new physicochemical, spectral, diffraction, refractometric effects related to heterogeneity in the changing heterogeneous structure of the surface layers of these solutions has hindered until now. The paper presents the results of vertical laser sensing of drops of hydrophilic substances highly diluted in water, which made it possible to detect clathrate nano-formations in various combinations. We studied droplets of distilled micellar water, hydrogen peroxide, an aqueous solution of glycerol, ethanol, etc. At low concentrations of hydrophilic substances in aqueous solutions, their molecules introduced into the interstices of the water lattice, without causing destruction of its structure. The dissolution mechanism continued only to a certain critical concentration, after which "saturation" is occurred. A further increase in the content of solute in the solution led to the destruction of the ordered structure, and the excess molecules of the hydrophilic substance combined to form complex aggregates.

Dmitry V. Nesterenko, Roman A. Pavelkin, Shinji Hayashi and Victor Soifer * Asymmetric resonances and field enhancement of hybrid plasmon-waveguide modes in CdTe structures *

The planar metal-dielectric structures based on a CdTe waveguide separated from a metal layer by a layer of silicon dioxide support excitation of propagating hybrid plasmon-waveguide modes. The mode's intercoupling results in the appearance of asymmetric resonance line shapes in spectra. We characterize asymmetric resonances of plasmon-induced transparency-like and Fano line shapes in the attenuated total reflection spectra of the structures within the framework of rigorous electromagnetic theory in the infrared region. The study of characteristic resonance regions demonstrated the effects of field redistribution between the interacting hybrid modes in a wide range of their propagation constants. Obtained results can lead to development of applications in sensing and enhanced infrared spectroscopies.

Fikret Mirzade and Rinad Seidgazov * Combined effects of surface elasticity and strain gradient on the instability of laser-excited films with nanoscale thickness *

A coupled diffusion-strain model of the dynamics of local disorder carriers (atomic defects) is presented to study the effect of the surface elastic properties and the strain gradient on the instability of a laser-excited plate with a nanoscale thickness. It is shown that the analysis, which simultaneously includes the nonlocal nature of the interaction of carriers with lattice atoms, surface elasticity, and normal and lateral defect forces that cause the surface layer to bend, gives two maxima on the instability growth rate curve at a sufficiently far above the instability threshold.

Dmitrij Belousov * Analysis of the ordering and area of defects of the TLIPSS structures formed on thin Hf films by astigmatic Gaussian beam *

The results of a quantitative evaluation of the ordering and area of defects of laser-induced periodic surface structures formed on 15 nm Hf film by analyzing their microimages are presented. The investigated structures were produced by astigmatically focused femtosecond Gaussian laser beam with 1026 nm wavelength and 150 μm beam size along the major axis. The dependences of the above-described parameters of the periodic structures on the scanning speed and writing beam power have been obtained. The use of hafnium films allowed forming highly ordered gratings with a period of 650-720 nm at scanning speeds of to 2 mm/s.

Mikhail Evseev and Eugene Bashkirov * Dynamics of entanglement of two superconducting qubits nonresonantly interacting with two independent resonators *

In the present work, we studied the dynamics of entanglement of the states of two superconducting qubits interacting with two microwave modes of independent resonators in the framework of the nonresonant double Janes-Cummings model. The model assumes various frequency mismatches of the resonator fields and atom-field interaction constants. An analytical solution to the model was obtained. The dependence of atomic entanglement on frequency disturbances of resonator fields and transitions in two-level systems was revealed.

А. Bugaev * Resonant nanophotonics structures for analog optical computing *

Sergey Volchkov, Leonid Kochkurov and Dmitry Zimnyakov * Effective dielectric function of semiconductor particles under intense laser pumping *

A method for recovery of the pump-intensity-dependent effective dielectric function of semiconductor particles is presented. Values of the intensity of non-linear scattering and the non-linear absorption coefficient are used as raw data for the recovery. These values are obtained using a modified z-scan technique with simultaneous detection of the scattering intensity at a given scattering angle. Modifications of the method applicable for Rayleigh and Mie scattering systems are discussed.
