  1. 1. Attosecond Electron Wave Packet Interferences

    Detta är en avhandling från Division of Atomic Physics, Department of Physics, Faculty of Engineering, LTH, Lund University

    Författare :Thomas Remetter; Lund University.; Lunds universitet.; [2008]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Attosecond Bound Electron Wave Packet Dynamics; Attosecond Pulse Train; High-Order Harmonics; Electron Wave Packet Interferometry; Attosecond Physics;

    Sammanfattning : 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. LÄS MER

  5. 5. Heavy particle interference and diffraction in fast electron transfer collisions

    Detta är en avhandling från Stockholm : Department of Physics, Stockholm University

    Författare :Magnus Gudmundsson; Stockholms universitet.; [2011]
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik; fysik; Physics;

    Sammanfattning : This thesis presents experimental results from the synchrotron cooler and storage ring CRYRING on charge transfer processes in fast electron transfer collisions using high-resolution cold target recoil-ion momentum spectroscopy. The main focus of these studies was to investigate a key concept of quantum mechanics: the wave-particle duality. LÄS MER
