    Sammanfattning : The aim of this thesis was to explore the prevalence of parentally experienced infant sleep problems, with special interest in severe problems, in a total community sample of 2 518 infants aged between 6 and 18 months. Factors associated with severe sleep problems were sought. LÄS MER

  4. 3. Correlated Electronic Structure of Materials : Development and Application of Dynamical Mean Field Theory

    Författare :Patrik Thunström; Olle Eriksson; Alexander Lichtenstein; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; DFT; DMFT; correlation; entanglement; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : This thesis is dedicated to the development, implementation and application of a combination of Density Functional Theory and Dynamical Mean Field Theory. The resulting program is shown through several examples to be a powerful and flexible tool for calculating the electronic structure of strongly correlated materials. LÄS MER

  5. 4. Magnetism in Transition Metal Systems : Interplay between structure, dimensionality and electron correlation

    Författare :Samara Keshavarz Hedayati; Yaroslav Kvashnin; Patrik Thunström; Olle Eriksson; Tamio Oguchi; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Sammanfattning : In this thesis, an ab initio study of electronic structures and magnetic properties of transition metal systems has been presented, covering bulk, interface and surface geometries. Among them are Fe, Co, Ni, CaMnO3, Co2MnSi, a ferromagnetic Heusler alloy, as well as double-perovskites oxides such as Sr3(Fe1.25Ni0.75)O6 and Nd2NiMnO6. LÄS MER
