AB  - Recent LHC results on the appearance of sub-leading flow modes in PbPb collisions at 2.76 TeV, related to initial-state fluctuations, are analyzed and interpreted within the HYDJET++ model. Using the newly introduced Principal Component Analysis (PCA) method applied to two-particle azimuthal correlations extracted from the model calculations, the leading and sub-leading flow modes are studied as a function of the transverse momentum (p(T)) over a wide centrality range. The leading modes of the elliptic (v(2)((1))) and triangular (v(3)((1))) flow calculated with the HYDJET++ model reproduce rather well the v(2){2} and v(3){2} coefficients measured experimentally using the two-particle correlations. Within the p(T) LT = 3 GeV/c range, where hydrodynamics dominates, the sub-leading flow effects are greatest at the highest p(T) of around 3 GeV/c. The sub-leading elliptic flow mode (v(2)((2))), which corresponds to the n = 2 harmonic, has a small non-zero value and slowly increases from central to peripheral collisions, while the sub-leading triangular flow mode (v(3)((2))), which corresponds to the n = 3 harmonic, is even smaller and does not depend on centrality. For n = 2, the relative magnitude of the effect measured with respect to the leading flow mode shows a shallow minimum for semi-central collisions and increases for very central and for peripheral collisions. For the n = 3 case, there is no centrality dependence. The sub-leading flow mode results obtained from the HYDJET++ model are in rather good agreement with the experimental measurements of the CMS Collaboration.

AB  - The effects of Ar+ ion irradiation on Al/Ti multilayers at room temperature were investigated. Eight (Al/Ti) bilayers were deposited by d.c. ion sputtering on (100) Si wafers to a total thickness of similar to 300 nm. Ion irradiations were performed by 180 keV Ar+ ions with doses 1-6 x 10(16) ions cm(-2). After implantation the samples were vacuum annealed at 400 degrees C for 30 min. Ion irradiations induced intermixing of layer constituents. and for the highest fluence formation of AlTi and AlTi3 intermetallic phases in the vicinity of the mid projected range of the impact ions. Subsequent vacuum annealing of sample implanted to 6 x 10(16) ions cm(-2) lead to transformation of all deposited layers into AlTi3 and gamma-AlTi intermetallic phases, except for 3-4 layers close to the substrate which were out of range of the effects induced by ion implantation. It is assumed that Al-Ti reaction was initiated by thermal spikes and further enhanced by chemical driving forces, but only in the intermixed region. This procedure may be interesting for fabrication of Al-Ti intermetallic compounds tightly adhered on different substrates. (C) 2011 Elsevier B.V. All rights reserved.

AB  - The effects of argon ion irradiation on structural changes in Ta/Ti multilayers deposited on Si wafers were investigated. The starting structures consisted of sputter deposited 10 alternate Ta (similar to 23 nm) and Ti (similar to 17 nm) layers of a total thickness similar to 200 nm. They were irradiated at room temperature with 200 key Ar(+), to the fluences from 5 x 10(15) to 2 x 10(16) ions/cm(2). The projected ion range was around mid-depth of the multilayered structure, and maximum displacements per atom similar to 130. It was found that, despite of the relatively heavy ion irradiation, individual nanocrystalline Ta and Ti layers remain unmixed, keeping the same level of interface planarity. The changes observed in the mostly affected region are increase in lateral dimensions of crystal grains in individual layers, and incorporation of bubbles and defects that cause some stretching of the crystal lattice. Absence of interlayer mixing is assigned to Ta-Ti immiscibility (reaction enthalpy Delta H(f) = +2 kJ/mol). It is estimated that up to similar to 5 at.% interface mixing induced directly by collision cascades could be compensated by dynamic demixing due to chemical driving forces in the temperature relaxation regime. The results can be interesting towards developing radiation tolerant materials based on multilayered structures. (C) 2011 Elsevier B.V. All rights reserved.

AB  - Fundamental solitons pinned to the interface between three semi-infinite one-dimensional nonlinear dynamical chains, coupled at a single site, are investigated. The light propagation in the respective system with the self-attractive on-site cubic nonlinearity, which can be implemented as an array of nonlinear optical waveguides, is modeled by the system of three discrete nonlinear Schrodinger equations. The formation, stability and dynamics of symmetric and asymmetric fundamental solitons centered at the interface are investigated analytically by means of the variational approximation (VA) and in a numerical form. The VA predicts that two asymmetric and two antisymmetric branches exist in the entire parameter space, while four asymmetric modes and the symmetric one can be found below some critical value of the inter-lattice coupling parameter actually, past the symmetry-breaking bifurcation. At this bifurcation point, the symmetric branch is destabilized and two new asymmetric soliton branches appear, one stable and the other unstable. In this area, the antisymmetric branch changes its character, getting stabilized against oscillatory perturbations. In direct simulations, unstable symmetric modes radiate a part of their power, staying trapped around the interface. Highly unstable asymmetric modes transform into localized breathers traveling from the interface region across the lattice without significant power loss. (C) 2011 Elsevier B.V. All rights reserved.
