  2. 1. Ultra-intense laser-plasma interaction for applied and fundamental physics

    Author : Arkady Gonoskov; Mattias Marklund; Gert Brodin; Vladimir Tikhonchuk; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; ultra-intense laser; femtosecond pulse; plasma; relativistic phenomena; laser-driven acceleration; attosecond pulse generation; radiation reaction; fysik; Physics;

    Abstract : Rapid progress in ultra-intense laser technology has resulted in intensity levels surpassing 1022 W/cm2, reaching the highest possible density of electromagnetic energy amongst all controlled sources available in the laboratory. During recent decades, fast growth in available intensity has stimulated numerous studies based on the use of high intensity lasers as a unique tool for the initiation of nonlinear behavior in various basic systems: first molecules and atoms, then plasma resulting from the ionization of gases and solids, and, finally, pure vacuum.

  4. 2. Numerical study of flame dynamics

    Author : Arkady Petchenko; Vitaly Bychkov; Leonid Kagan; Umeå universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; combustion; Direct Numerical Simulation DNS ; turbulence; flame-vortex interaction; flame acceleration; flame-acoustic interaction; Physics; Fysik;

    Abstract : Modern industrial society is based on combustion with ever increasing standards on the efficiency of burning. One of the main combustion characteristics is the burning rate, which is influenced by intrinsic flame instabilities, external turbulence and flame interaction with walls of combustor and sound waves.

  5. 3. Electronic properties of complex interfaces and nanostructures

    Author : Paulo V. C. Medeiros; Sven Stafström; Gueorgui Gueorguiev; Jonas Björk; Arkady Krasheninnikov; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : This thesis investigates the structural and electronic properties of graphene, polyaromatic hydrocarbon (PAH) molecules, and other carbon-based materials, when interacting with metallic surfaces, as well as under the influence of different types of perturbations. Density functional theory, incorporating van der Waals interactions, has been employed. READ MORE

  6. 4. Alien Places in Late Soviet Science Fiction : The "Unexpected Encounters" of Arkady and Boris Strugatsky as Novels and Films

    Author : Henriette Cederlöf; Anna Ljunggren; Yvonne Howell; Stockholms universitet; []
    Keywords : HUMANIORA; HUMANITIES; Arkady Strugatsky; Boris Strugatsky; science fiction; heterotopia; paradigm shift; Soviet culture; 1970s; Gothic; adaptation; Stalker; Roadside Picnic; Dead Mountaineer s Hotel; Arkadij Strugatskij; Boris Strugatskij; paradigmskifte; science fiction; heterotopi; Sovjetunionen; 1970-talet; adaption; slaviska språk; Slavic Languages;

    Abstract : This dissertation deals with how science fiction reflects the shift in cultural paradigms that occurred in the Soviet Union between the 1960s and the 1970s. Interest was displaced from the rational to the irrational, from a scientific-technologically oriented optimism about the future to art, religion, philosophy and metaphysics. READ MORE
