  2. 6. Aspects of QCD and the Photon Structure

    Author : Christer Friberg; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; High energy interactions; QCD; Photons; Monte Carlo Event Generator; Leptoquarks; Colour Connections; cosmic rays; Kosmisk strålning; högenergi; Fysicumarkivet A:2000:Friberg;

    Abstract : In a single theoretical framework, real and virtual photon interactions are modeled for gamma-p and gamma-gamma collisions. The description covers aspects from the production of jets to total cross sections, where special emphasis is put on the range of uncertainty in the modeling of a resolved photon component.

  4. 7. Creation and Detection of Single Photons

    Author : Hatim Azzouz; Mohamed Bourennane; Sergey Cherednichenko; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; fysik; Physics;

    Abstract : A growing number of technologies employ quantum properties in order to produce solutions that surpass the performance of conventional devices, or to execute operations that are fundamentally impossible with classical systems alone. In the field of optical quantum information science, photons are utilized to encode, communicate and manipulate information, making them vitally important. READ MORE

  5. 8. Dynamics of Quantum Correlations with Photons : Experiments on bound entanglement and contextuality for application in quantum information

    Author : Elias Amselem; Mohamed Bourennane; Antonio Acín; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum information; quantum optics; foundations of quantum mechanics; entanglement; non-contextuality; Kochen-Specker theorem; parametric down-conversion; quantum state engineering; fysik; Physics;

    Abstract : The rapidly developing interdisciplinary field of quantum information, which merges quantum and information science, studies non-classical aspects of quantum systems. These studies are motivated by the promise that the non-classicality can be used to solve tasks more efficiently than classical methods would allow. READ MORE

  6. 9. Protons, other Light Ions, and 60Co Photons : Study of Energy Deposit Clustering via Track Structure Simulations

    Author : Gloria Bäckström; Anders Ahnesjö; Nina Tilly; José M. Fernández-Varea; Niels Bassler; Uppsala universitet; []
    Keywords : Proton; light ion; Co-60 photon; track structure Monte Carlo code; clustering patterns of energy deposit; RBE; Medicinsk radiofysik; Medical Radiophysics;

    Abstract : Radiotherapy aims to sterilize cancer cells through ionization induced damages to their DNA whilst trying to reduce dose burdens to healthy tissues. This can be achieved to a certain extent by optimizing the choice of radiation to treat the patient, i.e. the types of particles and their energy based on their specific interaction patterns.

  7. 10. Negative Ions Interacting with Photons and Electrons

    Author : Anton Lindahl; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Negative ions; electron correlation; electron affinity; photodetachment; electron collision;

    Abstract : Negative ions are atoms or molecules where an extra electron is bound to neutral system. The nature of negative ions differs fundamentally from neutral and positive systems. The induced dipole potential responsible for the binding of the extra electron supports only a few bound states with relatively small binding energies. READ MORE
