  1. 11. Quantitative Modeling of Gain in Quantum Cascade Lasers under Operational Intensities

    Författare :David Winge; Matematisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; non-linear response; quantum cascade lasers; modelling; Non-equilibrium Green s functions; Gain clamping; Fysicumarkivet A:2016:Winge; kvantkaskadlaser; terahertz; infrarött; Halvledarfysik; spektroskopi; simulering;

    Sammanfattning : This thesis adresses modeling of quantum cascade lasers using non-equilibrium Green’s functions. Focus lies on the quantitative modeling of the gain when the systems are exposed to strong laser fields, as under realistic opertional conditions. LÄS MER

  2. 12. NMR STUDIES ON STRUCTURE AND DYNAMICS OF TWO-DOMAIN PROTEINS

    Författare :Houman Ghasriani; Biofysikalisk kemi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Fysikalisk kemi; Biochemistry; Metabolism; Biokemi; metabolism; Physical chemistry; Molekylär biofysik; CRISP-3; NMR; 3D-structure; NMR relaxation; Molecular biophysics; Prostate cancer; EGF module; PSP94; Beta-microseminoprotein; Protein S;

    Sammanfattning : The general objective of the present thesis work was to examine 3-dimensional structure as well as the motional properties of two different types of two-domain proteins by solution-state NMR. One of the major tasks of this thesis work was to investigate the domain orientation of these molecules by employing residual dipolar couplings (RDC) which can be used as orientational restraints for increasing the accuracy of protein structures determined by NMR.
