  1. 1. Slow and stopped light by light-matter coherence control

    University dissertation from Stockholm : KTH

    Author : Jonas Tidström; KTH.; [2009]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; slow light; stored light; stopped light; light-matter coherence; electromagnetically induced transparency; rubidium atoms; NATURAL SCIENCES Physics; NATURVETENSKAP Fysik; TECHNOLOGY Electrical engineering; electronics and photonics Photonics; TEKNIKVETENSKAP Elektroteknik; elektronik och fotonik Fotonik;

    Abstract : In this thesis we study light-matter coherence phenomena related to the interaction of a coherent laser field and the so-called Λ-system, a three-level quantum system (e.g., an atom). We observe electromagnetically induced transparency (EIT), slow and stored light in hot rubidium vapor. READ MORE

  2. 2. Investigations into the evolution of biological networks

    University dissertation from Stockholm : Institutionen för biokemi och biofysik

    Author : Sara Light; Stockholms universitet.; [2006]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; evolution; scale-free network; metabolism; protein-protein interactions; protein hubs; NATURAL SCIENCES Chemistry Theoretical chemistry; NATURVETENSKAP Kemi Teoretisk kemi;

    Abstract : Individual proteins, and small collections of proteins, have been extensively studied for at least two hundred years. Today, more than 350 genomes have been completely sequenced and the proteomes of these genomes have been at least partially mapped. The inventory of protein coding genes is the first step toward understanding the cellular machinery. READ MORE

  3. 3. Light, stress and herbivory from photoprotection to trophic interactions using Arabidopsis thaliana as a model organism

    University dissertation from Umeå : Ekologi, miljö och geovetenskap

    Author : Martin Frenkel; Umeå universitet.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Arabidopsis thaliana; photoprotection; herbivory; light-stress; jasmonate; fitness; FDE; dual-choice; NATURAL SCIENCES Biology; NATURVETENSKAP Biologi;

    Abstract : Photosynthesis is the most important process for nearly all life on earth. Photosynthetic organisms capture and transfer light energy from the sun into chemical energy which in turn provides a resource base for heterotrophic organisms. Natural light regimes are irregular and vary over magnitudes. READ MORE

    Abstract : Popular Abstract in Swedish HIMMELSKOMPASSEN En orienterare förlitar sig på karta och kompass för att finna sin väg genom skogen. När solen börjar gå ner blir det allt svårare att urskilja den röda kompassnålens riktning och detaljerna på kartan. Orienteraren slår slutligen på sin pannlampa och fortsätter springa mot sitt mål.
