Also known as a honeycomb lattice, the lattice formed by carbon atoms in the graphene phase can be rolled up to form nanotubes of various dimensions. Graphene nanotubes have many important applications, some of which rely on their unusual electrical conductivity and related properties. Quantum walks on graphs provide an abstract setting in which to study such transport properties independent of the other chemical and physical properties of a physical substance. They can thus be used to further the understanding of mechanisms behind such properties. We find that nanotube structures are significantly more efficient in transporting a quantum walk than cycles of equivalent size, provided the symmetry of the structure is respected in how they are used. We find faster transport on zig-zag nanotubes compared to armchair nanotubes, which is unexpected given that for the actual materials the armchair nanotube is metallic, while the zig-zag is semiconducting.

of the Supernovae, as well as the basic principles of radiobiology.
We have been able to:
1. Reconsider the danger of Supernova neutrinos in relation to
previous work and their applicability in the light of recent progress
in radiobiology (Especially the work of Cossairt despite his relative
success in computing the neutrino dose from SNe).
2. Making use of the work on simulation of the neutrino spectrum in
massive SNe stars from new generation of detectors (Like HyperSuper-Kamiokande), and from the estimated neutrino flux, we
compute the total dose in function of the distance.
3. We were then able to give a new of the limiting distance of
exploding supernovae which may constitute a danger on Earth.Diplôme : Magistère En ligne : ../theses/physique/ABOU2611.pdf Format de la ressource électronique : Permalink : index.php?lvl=notice_display&id=6956 نوترينو المستعرات العظمى و تأثيره على الأرض [texte imprimé] / حمزة بوقرورة ; جامعة منتوري, Éditeur scientifique ; جمال ميموني, Directeur de thèse . - 2009 . - 78 و. ; 30 سم.
