 On the theory of a non-linear neutral scalar field with spontaneously broken symmetry / Poluektov, Yu M On the example of a real scalar field, an approach to quantization of non-linear fields and construction of the perturbation theory with account of spontaneous symmetry breaking is proposed. The method is based on using as the main approximation of the relativistic self-consistent field model, in which the influence of vacuum fluctuations is taken into account in constructing the one-particle states.

 Unidirectional and Wavelength Selective Photonic Sphere-Array Nanoantennas / Liu, Yang G ; Choy, Wallace C H ; Sha, Wei E I ; Chew, Weng Cho We design a photonic sphere-array nanoantenna (NA) exhibiting both strong directionality and wavelength selectivity. Although the geometric configuration of the photonic NA resembles a plasmonic Yagi-Uda NA, it has different working principles, and most importantly, reduces the inherent metallic loss from plasmonic elements.

 Observing Abnormally Large Group Velocity at the Plasmonic Band Edge via a Universal Eigenvalue Analysis / Sha, Wei E I ; Meng, Ling Ling ; Choy, Wallace C H ; Chew, Weng Cho We developed a novel universal eigenvalue analysis for 2D arbitrary nanostructures comprising dispersive and lossy materials. The complex dispersion relation (or complex Bloch band structure) of a metallic grating is rigorously calculated by the proposed algorithm with the finite-difference implementation.

 A note on the breathing mode of an elastic sphere in Newtonian and complex fluids / Galstyan, Vahe ; Pak, On Shun ; Stone, Howard A Experiments on the acoustic vibrations of elastic nanostructures in fluid media have been used to study the mechanical properties of materials, as well as for mechanical and biological sensing. The medium surrounding the nanostructure is typically modeled as a Newtonian fluid. [...] arXiv:1506.09212.- 2015 - Published in : Physics of Fluids, 27 (3), 032001, 2015 External link: Preprint

 Control of atomic transition rates via laser light shaping / Jauregui, R A modular systematic analysis of the feasibility of modifying atomic transition rates by tailoring the electromagnetic field of an external coherent light source is presented. The formalism considers both the center of mass and internal degrees of freedom of the atom, and all properties of the field: frequency, angular spectrum, and polarization.

 Anion emission from water molecules colliding with positive ions: Identification of binary and many-body processes / Chesnel, J -Y ; Juhász, Z ; Lattouf, E ; Tanis, J A ; Huber, B A ; Bene, E ; Kovács, S T S ; Herczku, P ; Méry, A ; Poully, J -C et al. It is shown that negative ions are ejected from gas-phase water molecules when bombarded with positive ions at keV energies typical of solar-wind velocities. This finding is relevant for studies of planetary and cometary atmospheres, as well as for radiolysis and radiobiology. [...] arXiv:1506.09006.- 2015 - 5 p. - Published in : Phys. Rev.

 $\mathcal{PT}$-Symmetry-Breaking Chaos in Optomechanics / Lü, Xin-You ; Jing, Hui ; Ma, Jin-Yong ; Wu, Ying We demonstrate a $\mathcal{PT}$-symmetry-breaking chaos in optomechanical system (OMS), which features an ultralow driving threshold. In principle, this chaos will emerge once a driving laser is applied to the cavity mode and lasts for a period of time. [...] arXiv:1506.08917.- 2015 - 5 p. - Published in : Phys. Rev.

 Multifractal characterization of gold market: a multifractal detrended fluctuation analysis / Mali, Provash ; Mukhopadhyay, Amitabha The multifractal detrended fluctuation analysis technique is employed to analyze the time series of gold consumer price index (CPI) and the market trend of three world's highest gold consuming countries, namely China, India and Turkey for the period: 1993-July 2013. Various multifractal variables, such as the generalized Hurst exponent, the multifractal exponent and the singularity spectrum, are calculated and the results are fitted to the generalized binomial multifractal (GBM) series that consists of only two parameters.

 Configuration Mixing of Quark States in Baryons / Saghai, B ; Li, Z Mixing angles are used to describe the $SU(6)\otimes O(3)$ symmetry breaking in $\left[70,~1^-\right]$ multiplet in the sector of the lowest mass nucleon resonances, which are investigated extensively in constituent quark models for baryon spectroscopy. The transition amplitudes for the meson photoproduction off nucleon can also be expressed in terms of the mixing angles to take into account the configuration mixing.
