Unveiling the nanostructured nature of pyrobitumen and shungite carbons through Raman, X-ray and theoretical analyses

Eric Faulques, Nataliya Kalashnyk, Yves Lulzac, Yves Moëlo

<div><p>X-ray powder diffraction and multi-wavelength Raman spectroscopy were employed to characterize carbonaceous geomaterials, offering the first nanostructural analysis of rare pyrobitumen (LP) samples from the Lopérec gold deposit in Brittany, France, by comparing them to Karelian…

Relation between interface symmetry and propagation robustness along domain walls based on valley topological photonic crystals

Gaëtan Lévêque, Pascal Szriftgiser, Alberto Amo, Yan Pennec

Valley photonic crystals provide efficient designs for the routing of light through channels in extremely compact geometries. The topological origin of the robust transport and the specific geometries under which it can take place have been questioned in recent studies. In this article, we…

Time arrow without past hypothesis: a toy model explanation

Pablo Arrighi, Gilles Dowek, Amélia Durbec

The laws of Physics are time-reversible, making no qualitative distinction between the past and the future—yet we can only go towards the future. This apparent contradiction is known as the ‘arrow of time problem’. Its current resolution states that the future is the direction of increasing entropy…
