  1. 1. Phenomenology of Exotic Decays of Vector-Like Quark X5/3 into Doubly-Charged ScalarXinto Doubly-Charged Scalar

    L3-uppsats, Uppsala universitet/Högenergifysik

    Författare :Jakub Salko; [2020]
    Nyckelord :;

    Sammanfattning : Searches for the Vector-Like Quarks usually look for their signatures assuming they decay purely into Standard Model particles. In this paper, we explore one possible exotic decay of the Vector-Like Quark with electric charge +5/3, X5/3. LÄS MER

  2. 2. Aqueous self-assembly behaviour alteration derived from primary structure changes of model peptides

    Master-uppsats, Lunds universitet/Kemiska institutionen

    Författare :Marcus Bäcklund; [2020]
    Nyckelord :Model peptides; self-assembly; SAXS; FTIR; CD; physical chemistry; fysikalisk kemi; Chemistry;

    Sammanfattning : Understanding of the self-assembly behaviour of peptides is of great interest within several different areas such as neurodegenerative diseases, biotechnology, and peptide pharmaceuticals. In this work we have compared the impact on the self-assembly behaviour derived from systematic changes of the primary structure of A8K, where A denotes alanine and K lysine. LÄS MER

  3. 3. The Chirality-Flow Method for Massive and Electroweak Amplitudes

    Master-uppsats, Lunds universitet/Teoretisk partikelfysik

    Författare :Joakim Alnefjord; [2020]
    Nyckelord :chirality-flow; chirality; flow; spinor-helicity; tree-level; diagram; amplitude; Physics and Astronomy;

    Sammanfattning : In this thesis I extend the chirality-flow method to the full standard model at tree-level by including massive particles and electroweak interactions. The chirality-flow method is a new diagrammatic method for calculating Feynman diagrams that is based on the spinor-helicity formalism, that before this thesis was written had been worked out for massless QED and QCD at tree-level.

  4. 4. Formulation of Model Problem for Chirality Induced Spin Selectivity Effect

    Kandidat-uppsats, Uppsala universitet/Materialteori

    Författare :Henrik Bruce; [2020]
    Nyckelord :Chirality; Spin selectivity; CISS;

    Sammanfattning : Spin dependent electron transport in chiral molecules, the so-called chirality induced spin selectivity (CISS) effect, have attracted much attention over the past few years. Experimentally the spin polarization has been detected, and there is a theoretical consensus on the necessity of both spin-orbit coupling and geometrical helicity in order to get a non-vanishing spin polarization.

  5. 5. Transient Dynamics and Core Tunneling in Vertical Spin-Vortex Pairs

    Master-uppsats, KTH/Nanostrukturfysik

    Författare :Milton Persson; [2019]
    Nyckelord :Spin-vortex; ultra fast vortex dynamics; milli-Kelvin temperatures; macroscopic quantum tunneling; Spinnvirvel; ultrasnabb virveldynamik; milli-Kelvin temperaturer; makroskopisk kvanttunnling;

    Sammanfattning : Spin-vortices in vertically spaced pairs of thin elliptical Permalloy nanoparticles are investigated. The two vortex cores with parallel out-of-plane magnetization exhibit a strong monopole-like attraction through the spacer much thinner than the core length, thus forming a bound core-core pair.
