  2. 6. Fluctuations of smooth linear statistics of determinantal point processes

    Author : Lambert Gaultier; Kurt Johansson; Igor Krasovsky; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Mathematics; Matematik;

    Abstract : We study eigenvalues of unitary invariant random matrices and other de-terminantal point processes. Paper A investigates some generalizations ofthe Gaussian Unitary Ensemble which are motivated by the physics of freefermions. READ MORE

    Author : Xinju Liu; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; GaN; AlN; multiple quantum well; Molecular beam epitaxy; Si 111 ; intersubband transition; sapphire; GaN template;

    Abstract : The III-nitride semiconductors: InN, GaN and AlN are promising for photonic, high power and high temperature electronic devices. Their large and direct band gaps cover the range 0.7 to 6.2 eV, i. READ MORE

  5. 8. Design and synthesis of rhodium and iridium bis-η2 diolefin catalysts: : Applications in C–C bond formation and asymmetric catalysis

    Author : Michaela Melcher; Centrum för analys och syntes; []
    Keywords : catalysis; transition metal; ligand design; enantioselectivity; cycloadditions;

    Abstract : This thesis deals with the design and synthesis of rhodium and iridium bis-η2 diolefin catalysts and their applications in C–C bond formation and asymmetric catalysis.More specifically, the second chapter describes the development of inter- and intramolecular (5+2) cycloadditions catalyzed by cationic iridium(I) complexes that lead to the formation of seven-membered rings in a single step.

  6. 9. Exploring the Magnetism of Ultra Thin 3d Transition Metal Films

    Author : Cecilia Andersson; Olof Karis; Dimitri Arvanitis; Chi-Chang Kao; Uppsala universitet; []
    Keywords : Physics; thin film; xmcd; xrms; exafs; anisotropy; magnetism; Fe; Ni; Co; Ag; Cu; Fysik;

    Abstract : In this thesis the magnetic and structural properties of ultra-thin 3d transition metals films have been investigated, in particular Fe, Ni and Co films. X-ray Magnetic Circular Dichroism (XMCD) has provided element specific spin (ms ) and orbital (ml ) moments per atom by utilizing the magneto optic sum-rules. READ MORE
