1. 6. Quantum scattering and interaction in graphene structures

   Författare :Anna Orlof; Vladimir Kozlov; Igor Zozoulenko; Heinz Siedentop; Linköpings universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES;

   Sammanfattning : Since its isolation in 2004, that resulted in the Nobel Prize award in 2010, graphene has been the object of an intense interest, due to its novel physics and possible applications in electronic devices. Graphene has many properties that differ it from usual semiconductors, for example its low-energy electrons behave like massless particles. LÄS MER

3. 7. Learning Physics through Transduction : A Social Semiotic Approach

   Författare :Trevor Stanton Volkwyn; John Airey; Bor Gregorcic; Cedric Linder; David Brookes; Uppsala universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Introductory physics; transduction; interactive engagement; social semiotics; representational competence; probeware; mathematical tools; 1-D kinematics; coordinate systems; magnetic field; pedagogical affordance; disciplinary affordance; Physics with specialization in Physics Education; Fysik med inriktning mot fysikens didaktik;

   Sammanfattning : This doctoral thesis details the introduction of the theoretical distinction between transformation and transduction to Physics Education Research. Transformation refers to the movement of meaning between semiotic resources within the same semiotic system (e.g. LÄS MER

4. 8. Symmetries and conservation laws

   Författare :Raisa Khamitova; Börje Nilsson; Claes Jougréus; Maria Luz Gandarias; Växjö universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; conservation law; Noether s theorem; Lie group analysis; Lie-Bäcklund transformations; basis of conservation laws; formal Lagrangian; self-adjoint equation; quasi-selfadjoint; equation; nonlocal conservation law; Mathematical physics; Matematisk fysik;

   Sammanfattning : Conservation laws play an important role in science. The aim of this thesis is to provide an overview and develop new methods for constructing conservation laws using Lie group theory. The derivation of conservation laws for invariant variational problems is based on Noether’s theorem. LÄS MER

5. 9. Educational technology for visualisation in upper secondary physics education : The case of GeoGebra

   Författare :Lorena Solvang; Jesper Haglund; Niklas Gericke; Ellen Karoline Henriksen; Karlstads universitet; []
   Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Representational competence; physics education; GeoGebra; Pedagogiskt arbete; Educational Work;

   Sammanfattning : In order to contribute to our understanding of how technologies can be used to visualise physical phenomena in order to support teaching and learning of the phenomena at hand, this licentiate thesis explores the ways in which visual representations created with GeoGebra can be used in upper-secondary physics education. In addition, this thesis provides a new model that can be used to characterise students’ representational competence. LÄS MER

7. 10. A classifying algebra for CFT boundary conditions

   Författare :Carl Stigner; Jürgen Fuchs; Alexei Semikhatov; Karlstads universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Boundary conditions; Conformal field theory; Factorization constraints; Modular tensor categories; TFT-construction; Mathematical physics; Matematisk fysik; Physics; Fysik;

   Sammanfattning : Conformal field theories (CFT) constitute an interesting class of twodimensionalquantum field theories, with applications in string theoryas well as condensed matter physics. The symmetries of a CFT can beencoded in the mathematical structure of a conformal vertex algebra. LÄS MER
