    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Magnetism; Superconductivity; Electron Correlation; DMFT; DFT; Actinides; multipoles; hidden order; magnetic anisotropy; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : This work presents new development and applications of ab-initio simulation tools for material science. Focus lies on materials with strong electronic correlation and strong spin-orbit coupling. LÄS MER

  3. 17. Coil Design and Related Studies for the Fusion-Fission Reactor Concept SFLM Hybrid

    Författare :Anders Hagnestål; Olov Ågren; Vladimir Moiseenko; Ladislav Bardos; Jan Scheffel; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fusion; Fission; Hybrid reactor; Actinides; Mirror Machine; Quadrupolar mirror; Coils; Fysik; Physics;

    Sammanfattning : A fusion-fission (hybrid) reactor is a combination of a fusion device and a subcritical fission reactor, where the fusion device acts as a neutron source and the power is mainly produced in the fission core. Hybrid reactors may be suitable for transmutation of transuranic isotopes in the spent nuclear fuel, due to the safety margin on criticality imposed by the subcritical fission core. LÄS MER

  5. 19. To fission or not to fission: 230Ac

    Författare :Anna Kawecka; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Heavy Elements; r-process; CERN; Actinides; Radioactive Beams; ISOLDE; Fission; ISS;

    Sammanfattning : Around half of the elements heavier than iron found in the Universe are believed to have been formed during the rapid neutron capture process (r-process). During the r-process, very neutron-rich nuclei are created through a series of neutron captures and β−-decay reactions. LÄS MER
