  2. 1. Design of new materials with crystal structure-related properties : The role of lone pair cations

    Author : Eleni Mitoudi Vagourdi; Mats Johnsson; Vadim Kessler; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Crystal structure determination; New oxohalide compounds; Lone-pair electrons; X-ray diffraction; Physical properties; Inorganic Chemistry; oorganisk kemi;

    Abstract : Non-centrosymmetry and low-dimensional arrangements, e.g. chains or layers, are very attractive structural characteristics of crystalline compounds since they are linked to some physical properties including nonlinear optical activity, ferroelectricity and magnetic frustration.

  4. 2. A new synthetic strategy for low-dimensional compounds : Lone pair cations and alkaline earth spacers

    Author : Rie Takagi Fredrickson; Mats Johnsson; Sven Lidin; Lars Kloo; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Alkaline earth; Lone pair elements; Low-dimensional compounds; Inorganic chemistry; Oorganisk kemi; oorganisk kemi; Inorganic Chemistry;

    Abstract : Complex transition metals oxyhalides containing a lone pair element, such as tellurium (IV), form an attractive research field because there is a high probability of finding new low-dimensionally arranged compounds and, particularly, a low-dimensionally arranged transition metals substructures, leading to interesting physical properties. Tellurium (IV) can drive the formation of many unusual structures because of its stereochemically active lone pair electrons, E. READ MORE

  5. 3. Photonic Qubits for Quantum Communication : Exploiting photon-pair correlations; from theory to applications

    Author : Maria Tengner; Anders Karlsson; Alexei Trifonov; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum communication; photon-pair sources; entanglement; Physics; Fysik;

    Abstract : For any communication, the conveyed information must be carried by some physical system. If this system is a quantum system rather than a classical one, its behavior will be governed by the laws of quantum mechanics. READ MORE

  6. 4. Quantum Coherence in the Single Cooper Pair Box

    Author : Kevin Bladh; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; coherent oscillations; single Cooper pair box; quantum coherence; radio frequency single electron transistor; cryogenic filters;

    Abstract : This thesis presents measurements of quantum coherence in a single Cooper pair box, where quantum oscillations of charge between a reservoir and a small superconducting island have been observed. The single Cooper pair box (SCB) consists of a small metallic island which is connected to a reservoir via a tunnel junction. READ MORE

  7. 5. Infidelity in Birds – Causes and Consequences of Extra-pair Paternity

    Author : Jakob Augustin; Göteborgs universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; extra-pair paternity; genetic benefits; heterozygosity; sex ratio; Riparia riparia; Tringa totanus; Vanellus vanellus; Charadrius alexandrinus;

    Abstract : Forty years ago, more than 90% of bird species were classified as monogamous and not very exciting systems for studies of e.g. sexual selection. READ MORE
