  1. 21. A Program for SU(N) Color Structure Decomposition into Multiplet Bases Using Wigner 3j and 6j Coefficients

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Andris Potrebko; [2020]
    Keywords : Colour Structure; QCD; Quantum Chromodynamics; SU N ; Multiplet bases; Color structures; Physics and Astronomy;

    Abstract : The increased capacity of elementary particle accelerators raises the demand for the simulation data of the experiments. One of the bottlenecks in the simulations is the QCD color structure calculation, which is usually treated using non-orthogonal and overcomplete sets of bases. READ MORE

  3. 22. Polymer Assisted Transfer of Graphene onto Semiconductor Substrates

    University essay from Lunds universitet/Förbränningsfysik; Lunds universitet/Synkrotronljusfysik

    Author : Jonathan Frisby; [2020]
    Keywords : Physics and Astronomy;

    Abstract : Since first being isolated in 2004, Graphene has been researched heavily because of its unique properties. Recently, interest has grown in graphene/semiconductor heterostructures. In this work, the transfer of graphene through the use of cellulose acetate butyrate (CAB) polymer is studied. READ MORE

  4. 23. Extending the Standard Model by a Dark and Visible Scalar Singlet

    University essay from Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Author : Aram Fatah; [2020]
    Keywords : The two real singlet model; higgs boson; dark matter; beyond the standard model; bsm; scalar; Physics and Astronomy;

    Abstract : In this thesis, we extend the Higgs sector of the Standard Model by two scalar singlets and impose a discrete Z2 symmetry on each of them, under which, both singlets are odd. One of the two scalar singlets will acquire a vacuum expectation value while the other one does not. READ MORE

  5. 24. High Magnetic Field in Low Temperature Vacuum Conditions : Magnet Design, Modeling and Testing

    University essay from Luleå tekniska universitet/Rymdteknik

    Author : Nehir Schmid; [2020]
    Keywords : magnet; pulsed magnet; X-ray diffraction; crystallography; zylon; magnet design; magnetic field; high magnetic field; strong magnetic field; split-coil magnet;

    Abstract : The Swiss Free Electron Laser (SwissFEL) at the Paul Scherrer Institute is a national prestige project that will enable ground breaking new x-ray scattering experiments in areas such as biology, chemistry and physics. A plannedactivity is to generate possibility for x-ray diffraction under high pulsed magnetic fields to explore quantum mattermaterials. READ MORE

  6. 25. Passivation of Gallium Arsenide Nanowires for Solar Cells

    University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Author : Austin Irish; [2019]
    Keywords : nanowires; semiconductors; solar cells; photovoltaics; passivation; electronics; chemistry; polymers; hydrazine; plasma; gallium; arsenic; iii-v; epitaxy; photoluminescence; time-resolved; spectroscopy; Physics and Astronomy;

    Abstract : A strategic and diverse set of passivation methods for gallium arsenide nanowires wasstudied. Using a time-resolved photoluminescence setup at100 Kand300 K, the radiativerecombination of charge carriers was resolved on a picosecond time scale. READ MORE
