On The Relativity of Redshifts: Does Space Really "Expand"? / Lewis, Geraint F
In classes on cosmology, students are often told that photons stretch as space expands, but just how physical is this picture? Does space really expand? In this article, we explore the notion of the redshift of light with Einstein's general theory of relativity, showing that the core underpinning principles reveal that redshifts are both simpler and more complex than you might naively think. This has significant implications for the observed redshifting of photons as they travel across the universe, often refereed to as the cosmological redshift, and for the idea of expanding space..

Absence of equilibrium chiral magnetic effect / Zubkov, M A
We analyse the $3+1$ D equilibrium chiral magnetic effect (CME). We apply derivative expansion to the Wigner transform of the two - point Green function. [...]

On the recurrence and Lyapunov time scales of the motion near the chaos border / Shevchenko, Ivan I
Conditions for the emergence of a statistical relationship between $T_r$, the chaotic transport (recurrence) time, and $T_L$, the local Lyapunov time (the inverse of the numerically measured largest Lyapunov characteristic exponent), are considered for the motion inside the chaotic layer around the separatrix of a nonlinear resonance. When numerical values of the Lyapunov exponents are measured on a time interval not greater than $T_r$, the relationship is shown to resemble the quadratic one. [...]

Synthesis of optical spring potentials in optomechanical systems / Slatyer, Harry J ; Guccione, Giovanni ; Cho, Young-Wook ; Buchler, Ben C ; Lam, Ping Koy
We propose a method to tailor the potential experienced by a moveable end mirror in a cavity optomechanical system by specifying the spectral properties of the input field. We show that by engineering the power spectral density of the cavity input field a desired force function can be approximated, with the accuracy of the approximation limited only by the linewidth of the cavity.

Gas sensing properties of multiwall carbon nanotubes decorated with Rh nanoparticles / Leghrib, Radouane ; Dufour, Thierry ; Demoisson, Frédéric ; Claessens, Nicolas ; Reniers, François ; Llobet, Eduard
In the present work, multiwalled carbon nanotubes were decorated with rhodium nanoparticles using a colloidal solution in the post-discharge of an RF atmospheric plasma of argon (Ar) or argon/oxygen (Ar:O$_2$). The properties of these hybrid materials towards the room temperature detection of NO$_2$, C$_2$H$_4$, CO, C$_6$H$_6$ and moisture were investigated and discussed in view of compositional and morphological studies.

Streaming potential modeling in fractured rock: Insights into the identification of hydraulically active fractures / Roubinet, D ; Linde, N ; Jougnot, D ; Irving, J
Numerous field experiments suggest that the self-potential (SP) geophysical method may allow for the detection of hydraulically active fractures and provide information about fracture properties. However, a lack of suitable numerical tools for modeling streaming potentials in fractured media prevents quantitative interpretation and limits our understanding of how the SP method can be used in this regard.

Optical and mechanical mode tuning in an optomechanical crystal with light-induced thermal effects / Navarro-Urrios, D ; Gomis-Bresco, J ; Capuj, N E ; Alzina, F ; Griol, A ; Puerto, D ; Martínez, A ; Sotomayor-Torres, C M
We report on the modification of the optical and mechanical properties of a silicon 1D optomechanical crystal cavity due to thermo-optic effects in a high phonon/photon population regime. The cavity heats up due to light absorption in a way that shifts the optical modes towards longer wavelengths and the mechanical modes to lower frequencies. [...]

Inkjet-printed vertically emitting solid-state organic lasers / Mhibik, Oussama (LPL) ; Chénais, Sébastien (LPL) ; Forget, Sébastien (LPL) ; Defranoux, Christophe (BEL-ENSMSE) ; Sanaur, Sébastien (BEL-ENSMSE)
In this paper, we show that Inkjet Printing can be successfully applied to external-cavity vertically-emitting thin-film organic lasers, and can be used to generate a diffraction-limited output beam with an output energy as high as 33.6 uJ with a slope efficiency S of 34%. Laser emission shows to be continuously tunable from 570 to 670 nm using an intracavity polymer-based Fabry-Perot etalon. [...]
