    Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; pedestrian crowds; stochastic differential equations; mean field; stochastic control; games; backward dynamics; sticky boundary; stochastic maximum principle; social conventions; folkmassor; stokastiska differentialekvationer; medelfält; stokastisk styrning; limaktiga randvillkor; stokastiska maximumprincipen; dynamik med ändvillkor; spel; konventioner;

    Abstract : This thesis consists of five appended papers, primarily addressingtopics in pedestrian crowd modeling and the formation of conventions.The first paper generalizes a pedestrian crowd model for competingsubcrowds to include nonlocal interactions and an arbitrary (butfinite) number of subcrowds.

  4. 2. Correlated Electronic Structure of Materials : Development and Application of Dynamical Mean Field Theory

    Author : Patrik Thunström; Olle Eriksson; Alexander Lichtenstein; Uppsala universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; DFT; DMFT; correlation; entanglement; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

    Abstract : This thesis is dedicated to the development, implementation and application of a combination of Density Functional Theory and Dynamical Mean Field Theory. The resulting program is shown through several examples to be a powerful and flexible tool for calculating the electronic structure of strongly correlated materials. READ MORE

  5. 3. Theoretical and Computational Studies of Strongly Correlated Electron Systems : Dynamical Mean Field Theory, X-ray Absorption Spectroscopy and Analytical Continuation

    Author : Johan Schött; Olle Eriksson; Igor Di Marco; Oscar Grånäs; Patrik Thunström; Tim Wehling; Uppsala universitet; []
