  2. 6. Transmission Electron Microscopy for Characterization of Structures, Interfaces and Magnetic Moments in Magnetic Thin Films and Multilayers

    Author : Hans Lidbaum; Klaus Leifer; Peter Svedlindh; Josef Zweck; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Transmission electron microscopy; TEM; magnetism; multilayer; superlattice; thin films; amorphous metals; electron energy-loss magnetic circular dichroism; EMCD; electron diffraction; Magnetism; Magnetism; Surfaces and interfaces; Ytor och mellanytor; Physics; Fysik; Engineering Science with specialization in Solid State Physics; Teknisk fysik med inriktning mot fasta tillståndets fysik; Materiefysik; Physics of Matter;

    Abstract : Structural characterization is essential for the understanding of the magnetic properties of thin films and multilayers. In this thesis, both crystalline and amorphous thin films and multilayers were analyzed utilizing transmission electron microscopy (TEM). READ MORE

  4. 7. Topological excitations in field theory models of superconductivity and magnetism

    Author : Philipp Rybakov; Egor Babaev; Maxim Mostovoy; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik; Physics; Teoretisk fysik; Theoretical Physics;

    Abstract : Topological excitations are subjects of intensive studies in physics and mathematics. In solid-state and soft matter physics, topological excitations can largely determine the thermodynamic and electromagnetic properties of materials, while in high energy physics they were theorized as particles.

  5. 8. Theoretical studies of X-ray induced nuclear dynamics

    Author : Ivaylo Minkov; Hans Ågren; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical physics; Teoretisk fysik; Physics; Fysik;

    Abstract : The present thesis is a theoretical study of several x-ray spectroscopies { x-ray absorption, xray photoelectron, radiative and non-radiative resonant Raman scattering spectroscopy. The main focus point is investigating the role of the nuclear dynamics in molecules (naphthalene, biphenyl, the water dimer, HCl) on these spectra. READ MORE

  6. 9. Numerical Simulations of Plasmonic Nanostructures

    Author : Joan Alegret; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; nanoholes; DDA; Green s tensor; nanostructures; surface plasmons;

    Abstract : This thesis focuses on the study of metallic nanostructures that support plasmons. Special emphasis is devoted to two specific numerical methods that allow us to predict plasmon characteristics: the discrete dipole approximation (DDA) and the Green's tensor (GT) method. READ MORE
