  1. 1. Mathematical Reasoning : In physics and real-life context

    University dissertation from Göteborg : Chalmers University of Technology and University of Gothenburg

    Author : Helena Johansson; Göteborgs universitet.; Gothenburg University.; [2015]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Creative mathematical reasoning; Descriptive statistics; Differential item functioning; Figurative context; Imitative reasoning; Mathematical Reasoning Requirements; Mathematics tasks; National tests; Physics tasks; Real-life context; T-test; Upper secondary school;

    Abstract : This thesis is a compilation of four papers in which mathematical reasoning is examined in various contexts, in which mathematics is an integral part. It is known from previous studies that a focus on rote learning and procedural mathematical reasoning hamper students’ learning of mathematics. READ MORE

  2. 2. Effects of the Spin-Orbit Interaction on Transport and Optical Properties of III-V Semiconductor Quantum Wells

    University dissertation from Division of Solid State Theory, Department of Physics, University of Lund, Sölvegatan 14A, SE-223 62 Lund

    Author : Vladimir Froltsov; Lunds universitet.; Lund University.; [2000]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; spin-orbit interaction; quantum well; III-V; Raman scattering; magnetoresistance; weak localization; spin distribution; magnetic field; Fysik; Physics; Fysicumarkivet A:2000:Froltsov; Halvledarfysik; Semiconductory physics; semiconductor;

    Abstract : Effects of the intrinsic electron spin-orbit interaction on transport and optical properties of III-V semiconductor quantum wells have been studied theoretically. It is shown that due to crystal anisotropy of this interaction, the weak localization magnetoresistance in a magnetic field parallel to interfaces is very sensitive to the epitaxy growth direction and also to the orientation of the magnetic field with respect to the crystal axes.

  4. 4. Fundamental properties of neutrinos: masses and mixings

    University dissertation from Mathematical Physics, Lund Institute of Technology, Lund University

    Author : Solveig Skadhauge; Lunds universitet.; Lund University.; [2002]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Matematisk och allmän teoretisk fysik; Fysik; Physics; quantum mechanics; classical mechanics; Mathematical and general theoretical physics; statistical physics; gravitation; relativity; statistisk fysik; termodynamik; thermodynamics; klassisk mekanik; kvantmekanik; relativitet; Fysicumarkivet A:2002:Skadhauge;

    Abstract : Neutrino physics is one of the fastest growing topic in phenomenological high energy physics. Neutrinos are elementary neutral particles and participate only in the weak interactions. For this reason it is very difficult to detect them experimentally. Nevertheless, much experimental progress has been obtained in the recent years. READ MORE

  5. 5. First principles methods for electronic structure calculations of solids

    University dissertation from Department of Theoretical Physics, Lund University

    Author : Martin Springer; Lunds universitet.; Lund University.; [1997]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; screened interaction; T-matrix; vertex function; GW approximation; Green function; density functional theory; gradient expansion; order N method; Physics; Fysik;

    Abstract : A straightforward gradient expansion of the exchange energy of a perturbed electron gas is performed. Studied perturbations range from very weak to those that produce, e.g., a silicon-like band structure with a band gap. READ MORE
