Photoexcitation Circular Dichroism in Chiral Molecules
S. Beaulieu, A. Comby, D. Descamps +13
Chirality is ubiquitous in nature and fundamental in science, from particle physics to metamaterials.The most established technique of chiral discrimination - photoabsorption circu…
Characterization and control of charge transfer in a tunnel junction
Julien Gabelli, Karl Thibault, Gabriel Gasse +2
Charge transfer in a tunnel junction is studied under dc and ac voltage bias using quantum shot noise. Under dc voltage bias , spectral density of noise measured within a very l…
Aspects of hard QCD processes in proton-nucleus collisions
François Arleo
Hard processes in high-energy proton-nucleus collisions are a powerful tool in order to investigate several importants aspects of QCD in a nuclear medium, such as nuclear shadowing…
Nuclear spin relaxation in n-GaAs: from insulating to metallic regime
M. Vladimirova, S. Cronenberger, D. Scalbert +7
Nuclear spin relaxation is studied in n-GaAs thick layers and microcavity samples with different electron densities. We reveal that both in metallic samples where electrons are fre…
Excitons in van der Waals materials: from monolayer to bulk hexagonal boron nitride
Jaakko Koskelo, Giorgia Fugallo, Mikko Hakala +3
We present a general picture of the exciton properties of layered materials in terms of the excitations of their single-layer building blocks. To this end, we derive a model excito…
3D magnetic reconnection and its application to solar flares
Miho Janvier
Solar flares are powerful radiations occuring in the Sun's atmosphere. They are powered by magnetic reconnection, a phemonenon that can convert magnetic energy into other forms of…
