  2. 1. Complexity Theory and Physics Education Research : The Case of Student Retention in Physics and Related Degree Programmes

    Author : Jonas Forsman; Cedric Linder; Ismo Koponen; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Physics Education Research; Complexity Theory; Student Retention; Physics with specialization in Physics Education; Fysik med inriktning mot fysikens didaktik;

    Abstract : This thesis explores the use of complexity theory in Physics Education Research as a way to examine the issue of student retention (a university’s ability to retain its students). University physics education is viewed through the concepts of nestedness and networked interactions. READ MORE

  4. 2. Strong Correlation Effects in Bosonic and Fermionic Systems Through an Unbiased Quantum Monte Carlo Approach

    Author : Emil Blomquist; Egor Babaev; Johan Carlström; Barbara Capogrosso Sansone; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Fysik; Physics; Teoretisk fysik; Theoretical Physics;

    Abstract : Strongly interacting many-body quantum systems constitute some of the most challenging problems in physics, and exact analytical solutions are rare. In this thesis, we will investigate the models of two such systems numerically using the unbiased worm-algorithm Monte Carlo method. READ MORE

  5. 3. Thin-film ultraviolet light-emitting diodes realized by electrochemical etching of AlGaN

    Author : Michael Alexander Bergmann; Chalmers tekniska högskola; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; thin-film flip-chip; light-emitting diodes; UVB; AlGaN; thermocompression bonding; substrate removal; ultraviolet light; electrochemical etching; heterogeneous integration; LEDs;

    Abstract : Ultraviolet (UV) light sources have a direct impact on everyone’s life. They are used to sterilize surfaces as well as for water purification. In addition, they are used in green houses to enhance health-promoting substances in plants, for phototherapy to treat skin diseases, for sensing and material curing. READ MORE

  6. 4. Science, Language, and Literacy : Case Studies of Learning in Swedish University Physics

    Author : John Airey; Cedric Linder; Roger Säljö; Uppsala universitet; []
