  2. 1. Isomeric yield ratio measurements with JYFLTRAP : In quest of the angular momentum of the primary fragments

    Author : Vasileios Rakopoulos; Mattias Lantz; Stephan Pomp; Andreas Solders; José Benlliure; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Nuclear physics; nuclear fission; angular momentum; fission fragments; isomeric yield ratios; fission products; scission; Penning trap.; Physics with specialization in Nuclear Physics; Fysik med inriktning mot kärnfysik;

    Abstract : In this thesis, isomeric yield ratios of twenty nuclides produced in the fission of natU and 232Th by protons at 25-MeV and natU by high-energy neutrons were studied. The experiments were performed at the IGISOL-JYFLTRAP facility at the University of Jyväskylä. READ MORE

  4. 2. All-Fiber System for Photonic States Carrying Orbital Angular Momentum : A Platform for Classical and Quantum Information Processing

    Author : Alvaro Alarcón; Guilherme B. Xavier; Sebastião de Pádua; Linköpings universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Quantum Communication; Optical communication; Orbital Angular Momentum; Photonic Lantern; Few-mode-fibers;

    Abstract : The protection of confidential data is a fundamental need in the society in which we live. This task becomes more relevant when observing that every day, data traffic increases exponentially, as well as the number of attacks on the telecommunication infra-structure. READ MORE

  5. 3. Transfer of Angular Momentum in Astrophysical Discs

    Author : Mattias Wahde; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Abstract : In this thesis a study of astrophysical discs, with emphasis on galactic discs, is presented. The frictional force acting on a small satellite galaxy, moving on a co-planar circular orbit in a galactic disc, is shown to be only weakly dependent on the velocity dispersion and the self-gravity of the disc.

  6. 4. Probing the Drip-Lines through Momentum Distributions

    Author : Martin Smedberg; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; momentum distributions; drip-line; diffraction; 17C; 119C; core shadowing; 6He; neutron stripping; radioactive beams; break-up; intermediate resonance; neutron halo; 8He; 8B; absorption; reaction mechanism;

    Abstract : About a decade ago it was found that nuclei in the vicinity of the neutron drip-line under certain circumstances develop very extended valence neutron distributions, a phenomenon today known as halo states. The recent development of radioactive nuclear beams has provided us with a perfect tool for investigating these particular nuclei. READ MORE

  7. 5. Momentum exchange between light and nanostructured matter

    Author : Daniel Andrén; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; phase-gradient metasurface; optical force and torque; metavehicle; momentum exchange.; nano-optics; rotary nanomotor; optical tweezers;

    Abstract : An object's translational and rotational motion is associated with linear and angular momenta. When multiple objects interact the exchange of momentum dictates the new system's motion. READ MORE
