  • Variations in the structural, electronic and optical properties of N-doped
           TiO2 with increasing N doping concentration
    • Authors: Matiullah Khan, Sahar Ramin Gul, Jing Li, Wenbin Cao
      Abstract: Modern Physics Letters B, Volume 29, Issue 08, 30 March 2015. Based on density functional theory, calculations were performed for geometrically optimized N-doped TiO2 models. The effect of N dopant and its increasing doping concentration on the band structure are elucidated. N doping narrowed the band gap of TiO2 and introduced isolated N 2p states within the band gap. The location of N 2p states within the band gap can be optimized by N doping concentration. All N-doped TiO2 models shifted the absorption edge of TiO2 toward visible light region and increasing N doping concentration improved the visible light absorption. N-doped TiO2 model having reduced band gap without any isolated states will improve the photocatalytic response. Our results provide strong theoretical background for existing experiments.

  • Planar waveguides in Yb3+-doped tellurite glasses fabricated by ion
           implantation of oxygen
    • Authors: Chun-Xiao Liu, Jun Xu, Zhi-Guang Zhou, Li-Li Fu, Rui-Lin Zheng, Wei-Nan Li, Hai-Tao Guo, She-Bao Lin, Wei Wei
      Abstract: Modern Physics Letters B, Volume 29, Issue 08, 30 March 2015. A planar waveguide is demonstrated in the Yb3+-doped tellurite glass, using (5+6) MeV O3+ ion implantation with doses of (4+8)×1014 ions/cm2. The implantation process of O3+ ions into the Yb3+-doped tellurite glass is simulated by the stopping and range of ions in matter (SRIM) 2010 code. The dark-mode spectra are measured by the prism-coupling system at λ = 632.8 nm. The reflectivity calculation method and the finite-difference beam propagation method are used to calculate the refractive index profile and the modal profile of transverse electric (TE) mode of the fabricated waveguide, respectively. The absorption spectra show that the transmission properties are not affected by the waveguide fabrication process.

  • Discrete solitons in Bragg environment with carbon nanotubes
    • Authors: Mikhail B. Belonenko, Julia V. Nevzorova, Elena N. Galkina
      Abstract: Modern Physics Letters B, Ahead of Print. In this paper, we study the propagation of ultrashort optical pulses, which can be regarded as discrete solitons in this case, when the medium with carbon nanotubes (CNTs), has spatially modulated refractive index. As a result we were able to obtain the effective equation, which represents an analog of the classical sine-Gordon equation. A detailed analysis of the dependence on various parameters of the problem has been performed.

  • Polymer models of the organization of chromosomes in the nucleus of cells
    • Authors: Andrea Maria Chiariello, Simona Bianco, Andrea Piccolo, Carlo Annunziatella, Mariano Barbieri, Ana Pombo, Mario Nicodemi
      Abstract: Modern Physics Letters B, Ahead of Print. Understanding the mechanisms that control the organization of chromosomes in the space of the nucleus of cells, and its contribution to gene regulation, is a key open issue in molecular biology. New technologies have shown that chromosomes have a complex 3D organization, which dynamically changes across organisms and cell types. To understand such complex behaviors, quantitative models from polymer physics have been developed, to find the principles of chromosome folding, their origin and function. Here, we provide a short review of recent progress in such an important research field where Physical and Life Sciences meet.

  • Achieving broadband electromagnetic transparency with transmission line
    • Authors: Tinghua Li, Ming Huang, Jingjing Yang, Xingui Xu, Min Chen
      Abstract: Modern Physics Letters B, Ahead of Print. Electromagnetic transparent device (ETD) capable of protecting the device inside without affecting its performance is a fascinating device with extensive application prospects. In this paper, an equivalent circuit method for realizing ETD using transmission line (TL) metamaterials is presented. The validity of such a method and the transparent effect of the device are demonstrated through the Agilent's Advanced Design System (ADS) circuit simulator. Moreover, the influence of the quality factor of lumped elements on the performance of the device and its broadband characteristics are also investigated. This work suggests an alternative way to achieve the broadband electromagnetic transparency and has great guiding significance for the practical fabrication of ETD.

  • Diameter-dependent thermodynamic and elastic properties of metallic
    • Authors: Jeewan Chandra, Kuldeep Kholiya
      Abstract: Modern Physics Letters B, Ahead of Print. A simple theoretical model has been proposed to study the diameter-dependent properties of metallic nanoparticles, i.e. Ag, Au, Al, Ni, Pb, Cu and Fe. The diameter-dependent thermodynamic properties includes melting temperature, Debye temperature, evaporation temperature, melting enthapy and melting entropy. The model is also extended to study the diameter-dependent elastic properties including bulk modulus, Young's modulus and thermal expansion coefficient. On comparison with available experimental findings and other theoretical approaches, the results obtained with the present formulation depict a close agreement and demonstrate the validity of the method proposed in the present paper.

  • Implementing Toffoli gate via weak cross-Kerr nonlinearity and classical
    • Authors: Qian Sun, Liu Ye
      Abstract: Modern Physics Letters B, Ahead of Print. We design an efficient optical circuit to realize a Toffoli gate via weak cross-Kerr nonlinearity and classical feedback. To obtain a high-fidelity gate, we probe different path detectors to minimize the influence from the environmental noise. Compared to previous proposals, our scheme does not need external auxiliary photons and is easy to implement in experiment.

  • Enhancement of transport properties introduced complex defect in
           (6, 3) carbon nanotubes
    • Authors: Cai-Ping Cheng, Hui-Fang Hu, Zhao-Jin Zhang, Xiaowei Wang, Ying Chen, Quanhui Liu, Ping Peng
      Abstract: Modern Physics Letters B, Ahead of Print. By applying density functional theory (DFT) combined with nonequilibrium Green's function method, we have investigated the electronic structures and quantum transport properties of (6, 3) spiral chiral single-walled carbon nanotubes (SCSWCNTs) in the presence of carboxyl (COOH)-containing defect complexes. COOH-B-MV complex defect in (6, 3) single-walled carbon nanotubes (SWCNT) was energetically favorable than COOH-B-SW and COOH-B-Per complexes. Our calculated results proved that the complex partially improved the transport properties of (6, 3) SWCNTs with COOH-B-MV complex, but reduced the efficient transmission channels of (6, 3) SWCNTs with COOH-B-SW and COOH-B-Per complexes. It is anticipated that metallic-like (6, 3) SWCNT with COOH-containing complex defects can exhibit large range variations in transport behaviors, which are strongly dependent on the coupling between COOH group and B-MV complex defect. These tremendous properties suggest potential application of COOH-containing B-doped complexes in CNTs-based nanoelectronic devices.

  • Stochastic resonance in second-order and underdamped asymmetric bistable
    • Authors: Yong-Feng Guo, Ya-Jun Shen, Jian-Guo Tan
      Abstract: Modern Physics Letters B, Ahead of Print. The phenomenon of stochastic resonance (SR) in a second-order and underdamped asymmetric bistable system is investigated. The second-order asymmetric bistable system with Gauss white noise is stochastically equivalent to two-dimensional Markovian process, and the exact expression of the signal-to-noise ratio (SNR) of system response in the presence of weak periodic driving force is obtained under the adiabatic condition and the theory of two-state model intensities. The influences of the damping parameter, asymmetry constant r and the Gaussian white noises on the SNR are discussed. The present calculation results show that, the increase of static asymmetry r and damping parameter γ can restrain the SR phenomenon appears. However, the increase of signal amplitude A can enhance SR.

  • Effect of Sn doping on the formation of silicon nanocrystal in silicon
           nitride films
    • Authors: Xiaobo Chen, Li Zhang
      Abstract: Modern Physics Letters B, Ahead of Print. Sn-doped silicon nanocrystals (Si-NCs) embedded in silicon nitride was synthesized by post-annealing of silicon-rich silicon nitride (SRN) films deposited by co-sputtering. The effects of Sn impurity on the Si crystallization behavior and photoluminescence (PL) in SRN films were investigated. Doping with Sn dopants enhances phase separation in SRN and thus accelerates the crystallization of silicon nanoparticles. It was also found that the existence of Sn decreases crystallization temperature, and could be as low as 800°C. In the Sn-doped samples, the crystalline volume fraction increases monotonically from 16.2% to 78.5% with increasing annealing temperature and the area densities of about ~2.2×1012 cm-2 can be achieved after annealing at 1100°C. In addition, the intensity of PL of the SRN film could be enhanced by adding Sn impurity.

  • Multi-granularity immunization strategy based on SIRS model in scale-free
    • Authors: Fuzhong Nian, Ke Wang
      Abstract: Modern Physics Letters B, Ahead of Print. In this paper, a new immunization strategy was established to prevent the epidemic spreading based on the principle of "Multi-granularity" and "Pre-warning Mechanism", which send different pre-warning signal with the risk rank of the susceptible node to be infected. The pre-warning means there is a higher risk that the susceptible node is more likely to be infected. The multi-granularity means the susceptible node is linked with multi-infected nodes. In our model, the effect of the different situation of the multi-granularity immunizations is compared and different spreading rates are adopted to describe the epidemic behavior of nodes. In addition the threshold value of epidemic outbreak is investigated, which makes the result more convincing. The theoretical analysis and the simulations indicate that the proposed immunization strategy is effective and it is also economic and feasible.

      Abstract: Modern Physics Letters B, Ahead of Print. In this paper, we propose an extended helicopter's rescuing model to explore the effects of multiple rescuing points on each helicopter's flying behavior during the whole rescuing process from the numerical perspective. The numerical results show that the proposed model can describe the qualitative effects of multiple rescuing points on each helicopter's speed, running trail and safe region.

      Abstract: Modern Physics Letters B, Ahead of Print. The crystal structure of the semiconductors TlFeSe2 and TlFeS2 has been studied by mean of neutron diffraction at room temperature and high pressure up to 4.2 GPa and 5.2 GPa, respectively. The chain-like monoclinic crystal structure with space group C2/m remains unchanged in both compounds in the entire pressure range. The anisotropic lattice compression and the large difference in the bulk modulus and the compressibility coefficients of the structural parameters of the two compounds have been observed. The mechanism of the observed phenomena was discussed. The enhancement of the one-dimensional antiferromagnetic and metallic character was predicted.

  • Tailored growth of in situAl4SiC4 in laser melted aluminum melt
    • Authors: Fei Chang, Dongdong Gu
      Abstract: Modern Physics Letters B, Ahead of Print. The crystallization and growth of in situ crystals during non-equilibrium laser rapid melting/solidification process is an important research topic in the fields of both Applied Physics and Materials Science. The present paper studies the development mechanisms of in situ formed Al4SiC4 ceramic phase within the selective laser melted SiC/AlSi10Mg composites. Two different-structured Al4SiC4 having strip and particle morphologies were disclosed and their growth mechanisms were influenced by laser linear energy density (LED). An elevated LED resulted in a larger degree formation of strip-structured Al4SiC4 with the gradually coarsened crystal sizes in its length and thickness. The homogeneously dispersed particle-shaped Al4SiC4 exhibited a considerably refined nanostructure with a proper increase in LED, but showing a significant coarsening of particles at an excessive LED.

  • Statistical theory for the compressible scalar turbulence with inviscid
    • Authors: Qionglin Ni
      Abstract: Modern Physics Letters B, Ahead of Print. We developed the statistical theory for compressible scalar turbulence in the inviscid limit, in which the spatial structures of the precursors of velocity and scalar discontinuities (i.e. preshock and prefront) were discussed. By analyzing the asymptotic statistics of scalar turbulence in the strong compression region, it was found that the prefront structure of scalar influenced negligible to the statistics of velocity gradient, except certain Mach number (M) modulations such as M-2/3 and M-4/3.
