  1. 1. Quantum Optics with Propagating Microwaves in Superconducting Circuits

    Författare :Io Chun Hoi; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; transmon; second-order correlation function; qubit; microwave photons; photon router; superconducting artificial atom; Autler-Townes splitting; quantum network; SQUID; superconducting circuits; cross-Kerr effect; antibunching; Mollow triplet; Josephson junction; quantum optics;

    Sammanfattning : We address recent advances in quantum optics with propagating microwavesin superconducting circuits. This research field exploits on the fact that the coupling between a superconducting artificial atom and propagating microwave photons in a one-dimensional (1D) open transmission line can be made strong enough to observe quantum effects, without using any cavity to confine the microwave photons.

  3. 2. Multiconfigurational perturbation theory

    Författare :Kerstin Andersson; Karlstads universitet; []
    Nyckelord :Electron correlation; CASSCF; multiconfigurational second-order perturbation theory; CASPT2; ozone; C; N; O; F; Si; P; S; Cl; Ni; benzene; pyridine; pyrazine; pyrimidine; pyridazine; s-triazine; electric properties; excited states; spectroscopic data;

    Sammanfattning : The aim of the thesis is to analyze a method which describes the electron correlation in atoms and molecules. The method is based on Rayleigh-Schrödinger perturbation theory with a partitioning of the Hamiltonian into a fairly simple zeroth-order operator and a perturbation operator. LÄS MER

  4. 3. Adiabatic Processes in the Janyes-Cummings model

    Författare :Fredrik Mattinson; KTH; []
    Nyckelord :;

    Sammanfattning : This thesis investigates adiabatic processes in ageneralized Jaynes-Cummings model with two modes. Thenew ideais to use the bare states from this model for a stimulatedRaman adiabatic passage (STIRAP) process. In earlier work,atomic states have been used as quantum states to achieveadiabatic transfer in both theoretical and experimental work. LÄS MER

  5. 4. Time Correlated Single Photon Spectroscopy on Pyramidal Quantum Dots

    Författare :Tomas Jemsson; Fredrik Karlsson; Per-Olof Holtz; Sytjugov Ilya; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES;

    Sammanfattning : Generation of non-classical light is both of fundamental interest and a common condition for quantum information applications (QIA). One feasible type of single photon emitter for QIA is based on semiconductor quantum dots (QDs), due to their atomic-like energy structure and their possibility to be integrated with other semiconductor devices on the same chip.

  7. 5. Radiation Induced Oxidative Dissolution of UO2

    Författare :Ella Ekeroth; Mats Jonsson; Bernd Grambow; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; radiation; radiolysis; UO2; spent nuclear fuel; radicals; oxidants; reductants; rate constants; dissolution; H2O2; H2; Nuclear chemistry; Kärnkemi;

    Sammanfattning : Sammanfattning Denna doktorsavhandling berör oxidativ upplösning av UO2 (som modellsubstans för utbränt kärnbränsle) orsakad av radiolys av vatten samt effekten av H2 på denna denna process. Hastighetskonstanter för oxidation av UO2-pulver med olika oxidanter såsom H2O2 har bestämts experimentellt. LÄS MER
