  2. 6. A General Formalism for Continuous Feedback Control in Quantum Systems

    Author : Björn Annby-Andersson; NanoLund: Centre for Nanoscience; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; quantum measurements; quantum control; stochastic thermodynamics; information thermodynamics; full count- ing statistics; open quantum systems; Quantum measurements; Quantum control; Stochastic thermodynamics; Information thermodynamics; Full counting statistics; Open quantum systems;

    Abstract : This thesis devolops a general formalism for continuous feedback control in quantum systems. The main result is a quantum Fokker-Planck master equation describing the joint dynamics of a quantum system and a detector with finite bandwidth. For a fast detector, this equation can be reduced to a Markovian master equation for the system dynamics. READ MORE

  4. 7. Social referencing in infancy

    Author : Gunilla Stenberg; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Abstract : In a social referencing process, the infant uses interpretative information displayed by another person, often the infant's parent, to help determine how to handle novel events, persons, and objects. The prime aim of Study I was to examine natural infant-mother interaction behaviors in terms of social referencing, when 10-month-old infants encountered a stranger. READ MORE

  5. 8. Sex differences in children's play behavior : A biological construction of gender?

    Author : Anna Servin; Uppsala universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Psychology; congenital adrenal hyperplasia; sex differences; children; play; expectations; wishes; hormones; biology; Psykologi; Psychology; Psykologi; Psychology; psykologi;

    Abstract : The present thesis addressed the question of what causes sex differences in children's play behavior.In Study I, it was found that mothers have rather sex-stereotyped expectations for how their 1- and 3-year-old children will behave at the age of five, as regards sex-typed activities.

  6. 9. Nonlinear Evolution in High Energy QCD

    Author : Emil Avsar; Teoretisk partikelfysik - Geonomgår omorganisation; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Elementarpartikelfysik; quantum field theory; DIS; Elementary particle physics; Saturation; QCD; Small-x Physics; kvantfältteori; High energy interactions; cosmic rays; Kosmisk strålning; högenergi;

    Abstract : QCD at very high energies is still not very well understood. Difficulties arise from a strong non-linear dynamics and also from nonperturbative physics. Detailed analytic calculations are often only possible either for simple toy models, or for asymptotically high energies. READ MORE

  7. 10. The mechanical Paul trap in the upper secondary physics laboratory

    Author : Sebastian Kilde Löfgren; Göteborgs universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; Physics education research; discipline-based education research; physics laboratory; design-based research; variation theory; model-based science; modelling; mechanical Paul trap; Paul trap.;

    Abstract : In physics, toy models are often used in popular science contexts. Further, toy models have also been used to communicate some important principles of abstract phenomena qualitatively. One such example can be found in the 1989 Nobel laureate Wolfgang Paul’s Nobel lecture. READ MORE
