  1. 1. Attosecond Electron Wave Packet Interferences

    Författare :Thomas Remetter; Atomfysik; []
    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

    Sammanfattning : 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. LÄS MER

  4. 3. Electron Transport in Nanowire Quantum Devices

    Författare :Henrik Nilsson; Fasta tillståndets fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Superconductivity; Spin-orbit coupling; the Kondo effect; the Zeeman effect; Quantum dots; Nanowire memories; Nanowire transistors; InSb; InAs; Nanowires; Electron transport; Andreev reflections; Nanowire RF-SET; Noise in nanowires;

    Sammanfattning : This thesis focuses on electron transport in semiconductor InAs/InP and InSb nanowire quantum devices. However, first the temperature dependence of classical charge transport in InSb nanowire field-effect transistors, FETs, is characterized, using InAs nanowire FETs as a reference. LÄS MER

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

    Författare :Magnus Gudmundsson; Henrik Cederquist; Henning Schmidt; Erik Horsdal; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics; 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
