  1. 11. Excited state dynamics in the strong coupling regime

    Författare :Jürgen Mony; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Strong exciton-photon coupling; Excited state dynamics; light-matter interactions; photoswitch; aggregated states;

    Sammanfattning : Strong exciton-photon coupling exhibits the possibility to modify photophysical and photochemical properties of organic molecules without changing their structure. This is due to the formation of hybrid light-matter states, called polaritons, which are created when the strong coupling regime is achieved. LÄS MER

  2. 12. Governing Decarbonisation : The State and the New Politics of Climate Change

    Författare :Roger Hildingsson; Statsvetenskapliga institutionen; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; climate politics; the environmental state; decarbonisation; low-carbon transition; energy transformation; authoritative steering; enabling; orchestrating; Sweden;

    Sammanfattning : This dissertation examines the “new climate politics of decarbonisation” and the role of the state as a site for progressive climate action. This new politics concerns transformative social change aimed at moving society away from its current dependence on fossil carbon energy. LÄS MER

  3. 13. Membrane-based nanocalorimetry for low temperature studies with high resolution and absolute accuracy

    Författare :Stella Tagliati; Andreas Rydh; Vladimir M. Krasnov; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Nanocalorimetry; specific heat; membrane-based calorimeter; AC steady state; frequency dependence; thermal link conductance; thermal relaxation; GeAu thermometer; numerical simulations; fysik; Physics;

    Sammanfattning : A differential, membrane-based nanocalorimeter has been designed and constructed for thermal studies of mesoscopic samples at low temperatures. The calorimeter is intended for sample masses from mg to sub-μg and a broad temperature range from above room temperature down to the sub-K region. LÄS MER

  4. 14. On Importance Sampling and Dependence Modeling

    Författare :Jens Svensson; Boualem Djehiche; Thomas Mikosch; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Mathematical statistics; Matematisk statistik;

    Sammanfattning : This thesis consists of four papers. In the first paper, Monte Carlo simulation for tail probabilities of heavy-tailed random walks is considered. Importance sampling algorithms are constructed by using mixtures of the original distribution with some other state-dependent distributions. LÄS MER

  5. 15. On diode-pumped solid-state lasers

    Författare :Jonas Hellström; Fredrik Laurell; Valdas Pasiskevicius; Klaus Petermann; KTH; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; near-infrared lasers; end-pumped lasers; Q-switching; erbium; ytterbium; GdCOB; KGW; KYW; Co:MALO; laser materials; thermal lensing; end-pumping; spectroscopy; conical refraction; volume Bragg gratings; holographic gratings; laser tuning; Physics; Fysik;

    Sammanfattning : The research that is presented in this thesis can be divided into two major parts. The first part concerns longitudinally pumped, bulk Er-Yb lasers. In these lasers, the main limitation is the thermal shortcomings of the phosphate glass host material. LÄS MER
