  2. 1. Multidimensional Fluorescence Polarization Imaging of Single Light Harvesting Complexes

    Author : Sumera Tubasum; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Light Harvesting Complexes; Single Molecule Spectroscopy; Polarization Spectroscopy; Exciton Dynamics; Spectral Disorder;

    Abstract : This thesis presents my research journey in the Department of Chemical Physics,Lund University. Multidimensional fluorescence polarization imaging is used to study single LH2s. The method uses linearly polarized excitation light and the emission is detected through a polarizer. READ MORE

  4. 2. Multi-species systems in optical lattices : From orbital physics in excited bands to effects of disorder

    Author : Fernanda Pinheiro; Jonas Larsson; Jani-Petri Martikainen; Ehud Altman; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Theoretical Physics; teoretisk fysik;

    Abstract : In this thesis we explore different aspects of the physics of multi-species atomic systems in optical lattices. In the first part we will study cold gases in the first and second excited bands of optical lattices - the p and d bands. READ MORE

  5. 3. Effects of Energetic Disorder on the Optoelectronic Properties of Organic Solar Cells

    Author : Nikolaos Felekidis; Martijn Kemerink; Olle Inganäs; Carsten Deibel; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : Organic photovoltaics (OPVs) is a promising low-cost and environmental-friendly technology currently achieving 12-14% power conversion efficiency. Despite the extensive focus of the research community over the last years, critical mechanisms defining the performance of OPVs are still topics of debate. READ MORE

  6. 4. Spectra and Dynamics of Excitations in Long-Range Correlated Structures

    Author : Lars Kroon; Rolf Riklund; Magnus Johansson; Jeroen Lamb; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quasicrystals; deterministic aperiodic superlattices; Markov chains; electronic structure and diffusion; elastic vibrations; Fraunhofer diffraction; discrete solitons; phase transitions; Condensed matter physics; Kondenserade materiens fysik;

    Abstract : Vad karaktäriserar en kristall? Svaret på denna till synes enkla fråga blir kanske att det är en anordning av atomer uppradade i periodiska mönster. Så ordnade strukturer kan studeras genom att det uppträder så kallade Braggtoppar i röntgendiffraktionsmönstret. READ MORE

  7. 5. Collagenous colitis. Epidemiology, risk factors, clinical presentation and associated autoimmune disorders

    Author : Lina Vigren; Gastroenterologi; []
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Autoimmunity; collagenous colitis; epidemiology; inflammatory bowel disease; lymphocytic colitis; microscopic colitis; smoking;

    Abstract : Collagenous colitis (CC) affects middle-aged women and results in chronic watery non-bloody diarrhoea. The incidence of CC has increased but has never been determined in southern Sweden. During the period 2001-2010 the mean annual incidence was stable; 5.4/105 (median age 71 years). READ MORE
