FRW Bulk Viscous Cosmology with Modified Chaplygin Gas in Flat Space / Saadat, H ; Pourhassan, B
In this paper we study FRW bulk viscous cosmology in presence of modified Chaplygin gas. We write modified Friedmann equations due to bulk viscosity and Chaplygin gas and obtain time-dependent energy density for the special case of flat space..

Interaction and charge transfer between dielectric spheres: exact and approximate analytical solutions / Lindén, Fredrik ; Cederquist, Henrik ; Zettergren, Henning
We present exact analytical solutions for charge transfer reactions between two arbitrarily charged hard dielectric spheres. These solutions, and the corresponding exact ones for sphere-sphere interaction energies, include sums that describe polarization effects to infinite orders in the inverse of the distance between the sphere centers.

Analysis of scalar dissipation in terms of vorticity geometry in isotropic turbulence / Gonzalez, Michel
The mechanisms promoting scalar dissipation through scalar gradient production are scrutinized in terms of vorticity alignment with respect to strain principal axes. For that purpose, a stochastic Lagrangian model for the velocity gradient tensor and the scalar gradient vector is used. [...]

Dimethylsilanone generation from pyrolysis of polysiloxanes filled with nanosized silica and ceria/silica / Kulyk, Kostiantyn ; Zettergren, Henning ; Gatchell, Michael ; Alexander, John D ; Borysenko, Mykola ; Palianytsia, Borys ; Larsson, Mats ; Kulik, Tetiana
Polydimethylsiloxane (PDMS) is a widely used organosilicon polymer often employed in formulations with fine oxide particles for various high temperature applications. Although PDMS is considered to be thermally stable and chemically inert, it is not always clear how the oxide filler influences its thermoresistance, decomposition chemistry and what reactive products are formed in the underlying thermal reactions.

On the origin of intrinsic randomness of Rayleigh-Benard turbulence / Lin, Zhiliang ; Wang, Lipo ; Liao, Shijun
It is of broad interest to understand how the evolution of non-equilibrium systems can be triggered and the role played by external perturbations. A famous example is the origin of randomness in the laminar-turbulence transition, which is raised in the pipe flow experiment by Reynolds as a century old unresolved problem. [...]

Stochastic phenomena in a fiber Raman amplifier / Kalashnikov, Vladimir ; Sergeyev, Sergey V ; Ania-Castanón, Juan Diego ; Jacobsen, Gunnar ; Popov, Sergei
The interplay of such cornerstones of modern nonlinear fiber optics as a nonlinearity, stochasticity and polarization leads to variety of the noise induced instabilities including polarization attraction and escape phenomena harnessing of which is a key to unlocking the fiber optic systems specifications required in high resolution spectroscopy, metrology, biomedicine and telecommunications. Here, by using direct stochastic modeling, the mapping of interplay of the Raman scattering-based nonlinearity, the random birefringence of a fiber, and the pump-to-signal intensity noise transfer has been done in terms of the fiber Raman amplifier parameters, namely polarization mode dispersion, the relative intensity noise of the pump laser, fiber length, and the signal power.

Energy shift of H-atom electrons due to Gibbons-Hawking thermal bath / Pardy, Miroslav
The electromagnetic shift of energy levels of H-atom electrons is determined by calculating an electron coupling to the Gibbons-Hawking electromagnetic field thermal bath. Energy shift of electrons in H-atom is determined in the framework of the non-relativistic quantum mechanics..

Highly efficient singular surface plasmon generation by achiral apertures / Jiang, Quanbo ; Pham, Aline ; Bellessa, Joel ; Huant, Serge ; Genet, Cyriaque ; Drezet, Aurélien
We report a highly efficient generation of singular surface plasmon (SP) field by an achiral plasmonic structure consisting of $\Lambda$-shaped apertures. Our quantitative analysis based on leakage radiation microscopy (LRM) demonstrates that the induced spin-orbit coupling can be tuned by adjusting the apex angle of the $\Lambda$-shaped aperture.

Directional and singular surface plasmon generation in chiral and achiral nanostructures demonstrated by Leakage Radiation Microscopy / Jiang, Quanbo ; Pham, Aline ; Berthel, Martin ; Huant, Serge ; Bellessa, Joel ; Genet, Cyriaque ; Drezet, Aurélien
In this paper, we describe the implementation of leakage radiation microscopy (LRM) to probe the chirality of plasmonic nanostructures. We demonstrate experimentally spin-driven directional coupling as well as vortex generation of surface plasmon polaritons (SPPs) by nanostructures built with T-shaped and $\Lambda$- shaped apertures.
