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

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

    Abstract : 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. READ MORE

  4. 2. The photophysics and functions of some naturally occurring carotenoids

    Author : Helena Billsten; Kemisk fysik; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; Fysikalisk kemi; xanthophyll-binding proteins; vibrational relaxation; light-harvesting complexes; carotenoid aggregates; carotenoids; excited states; femtosecond pump-probe spectroscopy; xanthophylls;

    Abstract : Carotenoids are one of the most widespread and important group of pigments in Nature and they can act as light-harvesting agents, photoprotectors and antioxidants. Mechanisms of their multiple functions are not fully understood mainly because their complicated photophysics involving ?dark? excited states. READ MORE

  5. 3. Strong Light-Matter Interactions and Formation of Hybrid States at the Nanoscale

    Author : Martin Wersäll; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; coherent interactions; localized surface plasmon resonances; strong coupling;

    Abstract : Noble metallic nanoparticles, which support localized surface plasmon resonances (LSPR), offer a variety of potential scientific and industrial utilizations. Due to their remarkable ability to confine light at nanoscale dimensions, far below the optical diffraction limit, plasmonic nanoparticles enable intricate light manipulations, which may be performed and exploited for a wide range of future revolutionary applications.

  6. 4. Statistical Physics of Protein Folding and Aggregation

    Author : Giorgio Favrin; Beräkningsbiologi och biologisk fysik - Genomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Two State; Physics; Fysik; Statistics; operations research; programming; aktuariematematik; programmering; operationsanalys; actuarial mathematics; Statistik; Simulations; Aggregation; Protein Folding; Fysicumarkivet A:2004:Favrin;

    Abstract : The mechanisms of protein folding and aggregation are investigated by computer simulations of all-atom and reduced models with sequence-based potentials. A quasi local Monte Carlo update is developed in order to efficiently sample proteins in the folded phase. READ MORE

  7. 5. On Specifying and Estimating Economic Growth as a Spatial Process : Convergence, Inequality, and Migration

    Author : Martin E. Gustafsson; Roger Bivand; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social and economic geography; Economic geography; economic growth; regional convergence; migration; spatial statistics; spatially correlated errors; geographical dependence; Kulturgeografi; Human geography; Kulturgeografi; kulturgeografi; Social and Economic Geography;

    Abstract : This thesis includes three self-contained papers. The first paper considers the effect of geographically dependent observations on cross-sectional growth convergence and proposes a way of decomposing the level of technology taking into account geographical variation in growth rates.
