  2. 1. Attosecond Electron Wave Packet Interferences

    Author : Thomas Remetter; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Attosecond Bound Electron Wave Packet Dynamics; Attosecond Pulse Train; High-Order Harmonics; Electron Wave Packet Interferometry; Attosecond Physics;

    Abstract : Attosecond pulses offer a new route to produce temporally localized electron wave packets (EWPs) that can easily be tailored by altering the properties of the attosecond pulses. In this thesis we will present different experiments, supported by theory, where attosecond EWPs are created in presence of a strong infrared (IR) field. READ MORE

  4. 2. Attosecond Wave Packet Metrology

    Author : Marko Swoboda; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Molecular dissociation; Electron wave packets; Pulse characterization; Two-color harmonic generation; Attosecond pulse trains; Single attosecond pulses; Resonant two-photon ionization; Fysicumarkivet A:2010:Swoboda;

    Abstract : Attosecond pulses allow the study of electrons on their natural timescale. They are created from the interaction of atoms with ultrashort, intense laser pulses whose electric field approaches the strength of inner-atomic electric fields. This thesis presents experiments around the generation, characterization and application of attosecond pulses. READ MORE

  5. 3. Electron Wave Packet Dynamics on the Attosecond Time Scale

    Author : Kathrin Klünder; Atomfysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Photoionization; Single attosecond pulses; Attosecond pulse trains; Electron wave packet; Electron dynamics; Interferometry; Photoemission time delay; Fysicumarkivet A:2012:Klünder; Stark spectroscopy;

    Abstract : One objective of attosecond science is to study electron dynamics in atoms and molecular systems on their natural time scale. This can be done using attosecond light pulses. READ MORE

  6. 4. Nucleon-Nucleon Scattering in a Wave-Packet Formalism

    Author : Sean Miller; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; nuclear physics; chiral potentials; two-nucleon scattering;

    Abstract : In this thesis I analyse the prospect of leveraging statistical analyses of the strong nuclear interaction by using the wave-packet continuum discretisation (WPCD) method to efficiently compute nucleon-nucleon (NN) scattering observables on a graphics processing unit (GPU). The WPCD method gives approximate solutions to the S-matrix at multiple scattering energies at the cost of a single eigendecomposition of the NN channel Hamiltonian. READ MORE
