Evanescent straight tapered-fiber coupling of ultra-high Q optomechanical micro-resonators in a low-vibration helium-4 exchange-gas cryostat / Rivière, R ; Arcizet, O ; Schliesser, A ; Kippenberg, T J
We developed an apparatus to couple a 50-micrometer diameter whispering-gallery silica microtoroidal resonator in a helium-4 cryostat using a straight optical tapered-fiber at 1550nm wavelength. On a top-loading probe specifically adapted for increased mechanical stability, we use a specifically-developed "cryotaper" to optically probe the cavity, allowing thus to record the calibrated mechanical spectrum of the optomechanical system at low temperatures.

Angular distributions of the vector Ay and tensor Ayy, Axx, Axz analyzing powers in the dd->3Hp reaction at 200 MeV / Kurilkin, A K ; Saito, T ; Ladygin, V P ; Uesaka, T ; Hatano, M ; Isupov, A Yu ; Janek, M ; Kato, H ; Ladygina, N B ; Maeda, Y et al.
A complete set of analyzing powers for the dd->3Hp reaction at the kinetic beam energy of 200 MeV has been measured in the full angular range in the c.m. frame. [...]

Deformation method for generalized Abelian Higgs-Chern-Simons models / Losano, L ; Malbouisson, J M C ; Rubiera-Garcia, D ; Santos, C dos
We present an extension of the deformation method applied to self-dual solutions of generalized Abelian Higgs-Chern-Simons models. Starting from a model defined by a potential $V(| \phi |)$ and a non-canonical kinetic term $\omega(| \phi |) | D_{\mu}\phi |^2$ whose analytical domain wall solutions are known, we show that this method allows to obtain an uncountable number of new analytical solutions of new models defined by other functions $\widetilde{V}$ and $\widetilde{\omega}$.

Stability Analysis of Thin-Shell Wormholes from Charged Black String / Sharif, M ; Azam, M
In this paper, we construct thin-shell wormholes from charged black string through cut and paste procedure and investigate its stability. We assume modified generalized Chaplygin gas as a dark energy fluid (exotic matter) present in the thin layer of matter-shell. [...]

Entanglement Structure in Expanding Universes / Nambu, Yasusada
We investigate entanglement of a quantum field in de Sitter spacetime using a particle detector model. By considering the entanglement between two comoving detectors interacting with a scalar field, it is possible to detect the entanglement of the scalar field by swapping it to detectors. [...]

Operation of a titanium nitride superconducting microresonator detector in the nonlinear regime / Swenson, L J ; Day, P K ; Eom, B H ; Leduc, H G ; Llombart, N ; McKenney, C M ; Noroozian, O ; Zmuidzinas, J
If driven sufficiently strongly, superconducting microresonators exhibit nonlinear behavior including response bifurcation. This behavior can arise from a variety of physical mechanisms including heating effects, grain boundaries or weak links, vortex penetration, or through the intrinsic nonlinearity of the kinetic inductance.

Weak and Extended H2 Emission in NGC 6369 / Ramos-Larios, Gerardo ; Guerrero, Martin A ; Vazquez, Roberto ; Phillips, John P
NGC 6369 is a double-shell PN with a filamentary outer shell or envelope and faint bipolar extensions. We have used ground- and space-based narrowband optical and near-IR images, broadband mid-IR images, optical long-slit echelle spectra, and mid-IR spectra to investigate its physical structure. [...]

Predicting the variance of a measurement with 1/f noise / Lenoir, Benjamin
Measurement devices always add noise to the signal of interest and it is necessary to evaluate the variance of the results. This article focuses on stationary random processes whose Power Spectrum Density is a power law of frequency. [...]

Efficient kinetic Monte Carlo method for reaction-diffusion processes with spatially varying annihilation rates / Schwarz, Karsten ; Rieger, Heiko
We present an efficient Monte Carlo method to simulate reaction-diffusion processes with spatially varying particle annihilation or transformation rates as it occurs for instance in the context of motor-driven intracellular transport. Like Green's function reaction dynamics and first-passage time methods, our algorithm avoids small diffusive hops by propagating sufficiently distant particles in large hops to the boundaries of protective domains.

The EUROnu Project / Edgecock, T R ; Caretta, O ; Davenne, T ; Densham, C ; Fitton, M ; Kelliher, D ; Loveridge, P ; Machida, S ; Prior, C ; Rogers, C et al.
The EUROnu project has studied three possible options for future, high intensity neutrino oscillation facilities in Europe. The first is a Super Beam, in which the neutrinos come from the decay of pions created by bombarding targets with a 4 MW proton beam from the CERN High Power Superconducting Proton Linac. [...]
