   Abstract : This thesis is a theoretical investigation of the effects of spin-orbit (SO) interactions in ferromagnetic metal nano-particles. Part I of the thesis is devoted to an elementary introduction of the research field, including recent experimental advances which partly motivated the work presented here. READ MORE

4. 2. Spin-Orbit and Spin-Spin Coupling in the Triplet State

   Author : Sathya Sai Ramakrishna Raj Perumal; Hans Ågren; Ulf Wahlgren; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Spin-spin; Spin-Orbit; D and E parameters; ZFS; graphene; TMM; OXA; diradicals; tris 8-hydroxyquinonline aluminium; magnetic anisotropy; magnetism; triplet;

   Abstract : The underlying theory of “Spin” of an electron and its associated inter-actions causing internal fields and spectral shift to bulk-magnetism iswell established now. Our understanding of spin properties is significant andmore useful than ever before. READ MORE

5. 3. Density Functional Theory Studies of Small Supported Gold Clusters and Related Questions : What a Difference an Atom Makes

   Author : Martin Amft; Natalia Skorodumova; Olle Eriksson; Hannu Häkkinen; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Gold clusters; CO oxidation; graphene; spin-orbit coupling; van der Waals interactions; thermally excited vibrations; Condensed matter physics; Kondenserade materiens fysik; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Abstract : During the last decades the specific manipulation of matter on the (sub-) nanometer scale, also known as nanoscience, became possible by technologies such as the scanning tunneling microscope. Nanocatalysts, i.e. catalytic active structures of up to a few nanometers in size, belong to this rather new class of materials. READ MORE

6. 4. Interaction and disorder in helical conductors

   Author : Anders Ström; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; physics; helical conductors; topological insulators; Anderson localization; condensed matter;

   Abstract : Different effects from electron-electron interactions and disorder in helical and quasi-helical conductors are studied using bosonisation and renormalisation group methods. The combined effects of Rashba spin-orbit interaction and magnetic Kondo-type impurities in the helical edge liquids of quantum spin Hall insulators, are investigated. READ MORE

7. 5. Theoretical Studies of Spin-Dependent Quantum Phenomena in Semiconductor Nanostructures

   Author : Patrik Brusheim; Fasta tillståndets fysik; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Zitterbewegung.; spin Hall effect; spintronics; Spin; quantum transport;

   Abstract : The study of spin transport has emerged at the forefront of condensed matter physics during the last decade. Much of the interest has undoubtedly been sparked by the advent of the spintronics paradigm and the idea of creating novel electronic devices based on the spin degree of freedom of the carriers.
