  2. 1. Studies of Gas Disks in Binary Systems

    Author : Miguel de Val Borro; Pawel Artymowicz; William Benz; Stockholms universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Astronomy; Astronomy; Astronomi; Astronomy; astronomi;

    Abstract : There are over 300 exoplanets detected through radial velocity surveys and photometric studies showing a tremendous variety of masses, compositions and orbital parameters. Understanding the way these planets formed and evolved within the circumstellar disks they were initially embedded in is a crucial issue. READ MORE

  4. 2. Few particle effects in pyramidal quantum dots - a spectroscopic study

    Author : Daniel Dufåker; Fredrik Karlsson; Per Olof Holtz; Val Zwiller; Linköpings universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES;

    Abstract : In this thesis two very similar processes have been studied, both involving excitations of particles during recombination of exciton complexes in quantum dots, reducing the energy of the emitted photon. Different exciton complexes are defined according to the number of electrons and holes in the quantum dot upon recombination. READ MORE

  5. 3. Integrated Photonics for Quantum Optics

    Author : Samuel Gyger; Val Zwiller; Stephan Steinhauer; Ali W. Elshaari; Marijn A. M. Versteegh; Matthew D. Shaw; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; integrated photonics; single-photons; single-photon sources; quantum dots; single-photon detectors; SNSPD; integrerad fotonik; enstaka fotoner; enstaka fotonkällor; kvantprickar; enstaka fotondetektorer; SNSPDs; Optics and Photonics; Optik och fotonik; Physics; Fysik;

    Abstract : Quantum physics allows us a vision of Nature's forces that bind the world, all its seeds and sources. After decades of primarily scientific research, we've arrived at a stage in time where quantum technology can be applied to practical problems and add value outside the field. READ MORE

  6. 4. Bright and strain-tunable semiconductor quantum dot devices

    Author : Thomas Lettner; Val Zwiller; Klaus D. Jöns; Oliver Benson; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum dots; single–photons; entanglement; strain–tunable; kvantprickar; singelfotoner; sammanflätning; töjnings-justerbar; Optik och fotonik; Optics and Photonics;

    Abstract : Optically active semiconductor quantum dots have proven to be excellent single- and entangled-photon sources, with applications in quantum optics and quantum photonics. These sources are considered crucial in the development of future photonic quantum technology, such as quantum communication, quantum computation and quantum metrology. READ MORE

  7. 5. The elephant in the cell : A multifaceted undertaking to uncover the molecular principles behind lymphatic endothelial cell identity

    Author : Virginia Panara; Katarzyna Koltowska; Taija Mäkinen; Marcel den Hoed; Sarah de Val; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lymphatic endothelium; Development; Epigenetic; Biologi med inriktning mot zoologisk utvecklingsbiologi; Biology with specialization in Animal Development;

    Abstract : The lymphatic vascular network is composed of a series of blind ended vessels, and is involved in physiological functions such as fluid homeostasis, lipid metabolism and immune trafficking. Despite lymphatic endothelial cells being derived from multiple organs, they share common molecular denominators, including the expression of the transcription factor Prox1.
