Evidence for light-by-light scattering in heavy-ion collisions with the ATLAS detector at the LHC
(Nature Publishing Group, 2017-02)
Light-by-light scattering (γγ → γγ) is a quantum-mechanical process that is forbidden in the classical theory of electrodynamics. This reaction is accessible at the Large Hadron Collider thanks to the large electromagnetic ...
CDW theoretical description of the single ionization of argon by positron and electron impact
(Elsevier Science, 2007-08)
In this work, we consider the single ionization of Ar by 200 eV positron and electron impact. The quantum mechanical continuum distorted wave (CDW) model is used in the one-active electron approximation. Parametrizations ...
Dispersion and damping of multiple quantum-well polaritons from resonant Brillouin scattering by folded acoustic modes
(American Physical Society, 2012-01)
We demonstrate that resonant Brillouin light scattering using ultranarrow lasers and high-resolution spectrometers provides unique access to the polariton lifetimes, a key parameter in their formation and dynamics. In very ...
Attenuation mechanisms in fractured fluid-saturated porous rocks: a numerical modelling study
(Wiley Blackwell Publishing, Inc, 2019-05)
Seismic attenuation mechanisms receive increasing attention for the characterization of fractured formations because of their inherent sensitivity to the hydraulic and elastic properties of the probed media. Attenuation ...
Light-like Wilson loops in ABJM and maximal transcendentality
(Springer Verlag Berlín, 2013-08)
We revisit the computation of the two-loop light-like tetragonal Wilson loop for three dimensional pure Chern-Simons and N=6 Chern-Simons-matter theory, within dimensional regularization with dimensional reduction scheme. ...
Camera-based CW diffuse optical tomography for obtaining 3D absorption maps by means of digital tomosynthesis
(IOP Publishing, 2020-11)
We present a novel method for obtaining a 3D absorption map of a tissue-like turbid slab in the near-infrared spectral range by tomosynthesis. Transmittance data are obtained for a large number of oblique projection ...
Quantum well photoelastic comb for ultra-high frequency cavity optomechanics
(IOP Publishing, 2018-12)
Optomechanical devices operated at their quantum limit open novel perspectives for the ultrasensitive determination of mass and displacement, and also in the broader field of quantum technologies. The access to higher ...
Diffraction in neutron imaging - A review
(Elsevier Science, 2018-01)
Neutron imaging is a highly successful experimental technique ever since adequate neutron sources were available. In general, neutron imaging is performed with a wide wavelength spectrum for best flux conditions in ...
Quantifying the effect of straylight on photopic contrast sensitivity
(Optical Society of America, 2018-07)
The visual performance of a reference group (RG) using diffuser filters was compared to a cataract-diagnosed group (CatG). Measurements of straylight (SL) parameter, photopic contrast sensitivity (CS), and visual acuity ...
How TOPO affects the interface of the novel mixed water/AOT:TOPO/n-heptane reverse micelles: dynamic light scattering and Fourier transform infrared spectroscopy studies
(Royal Society of Chemistry, 2014-06)
In this work we report for the first time the formation of two reverse micelle (RM) media produced by the nonionic surfactant tri-n-octyl phosphine oxide (TOPO) in n-heptane and the one produced by mixing the anionic sodium ...
