How Gaussian can our Universe be?
Giovanni Cabass, Enrico Pajer, Fabian Schmidt
Gravity is a non-linear theory, and hence, barring cancellations, the initial super-horizon perturbations produced by inflation must contain some minimum amount of mode coupling, o…
Holographic Thermalization and Generalized Vaidya-AdS Solutions in Massive Gravity
Ya-Peng Hu, Xiao-Xiong Zeng, Hai-Qing Zhang
We investigate the effect of massive graviton on the holographic thermalization process. Before doing this, we first find out the generalized Vaidya-AdS solutions in the de Rham-Ga…
Absorption and scattering by interstellar dust in the silicon K-edge of GX 5-1
S. T. Zeegers, E. Costantini, C. P. de Vries +6
We study the absorption and scattering of X-ray radiation by interstellar dust particles, which allows us to access the physical and chemical properties of dust. The interstellar d…
Patent Portfolio Analysis of Cities: Statistics and Maps of Technological Inventiveness
Dieter Franz Kogler, Gaston Heimeriks, Loet Leydesdorff
Cities are engines of the knowledge-based economy, because they are the primary sites of knowledge production activities that subsequently shape the rate and direction of technolog…
Holographic Photon Production and Anisotropic Flow
Ioannis Iatrakis, Elias Kiritsis, Chun Shen +1
The thermal-photon emission from strongly coupled gauge theories at finite temperature via the bottom-up models in holographic QCD in the deconfined phase is studied. The models ar…
Ultrafast all-optical gated amplifier based on ZnO nanowire lasing
Marijn A. M. Versteegh, Peter J. S. van Capel, Jaap I. Dijkhuis
We present an ultrafast all-optical gated amplifier, or transistor, consisting of a forest of ZnO nanowire lasers. A gate light pulse creates a dense electron-hole plasma and excit…
