2. 1. The Queerness of Objective Values : An Essay on Mackiean Metaethics and the Arguments from Queerness

   Author : Victor Moberger; Jens Johansson; Erik Carlson; Russ Shafer-Landau; Uppsala universitet; []
   Keywords : HUMANIORA; HUMANITIES; J. L. Mackie; argument from queerness; objective values; moral realism; claim to objectivity; argument from relativity; non-naturalism; supervenience; normative explanation; authoritative prescriptivity; objectivity; categoricity; minimal realism; ardent realism; Filosofi; Philosophy;

   Abstract : This book investigates the argument from queerness against moral realism, famously put forward by J. L. Mackie in Ethics: Inventing Right and Wrong (1977). The book can be divided into two parts. READ MORE

5. 3. Index theory in geometry and physics

   Author : Magnus C H T Goffeng; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Index theory; Cyclic cohomology; Regularized index formulas; Toeplitz operators; Pseudo-differential operators; Quantum Hall effect; Toeplitz operators;

   Abstract : This thesis contains three papers in the area of index theory and its applications in geometry and mathematical physics. These papers deal with the problems of calculating the charge deficiency on the Landau levels and that of finding explicit analytic formulas for mapping degrees of Hölder continuous mappings.

6. 4. Correlated materials : models and methods

   Author : Hugo Strand; Göteborgs universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; correlated electrons; Hubbard model; multiband Hubbard model; dynamical mean field theory; exact diagonalization; Landau theory; Mott metal-insulator transition; Gutzwiller method; many-body point group symmetry; ironchalcogenides; Kanamori interaction; Slater-Condon interaction;

   Abstract : This thesis encompass a series of studies on methods and models for electron systems with local interactions, relevant for correlated materials. The first study focus on the canonical model for local correlation, the Hubbard model. READ MORE

7. 5. Superconductivity in the presence of magnetic steps

   Author : Wafaa Assaad; Matematik LTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Ginzburg-Landau theory; Schrodinger operators with magnetic fields; Superconductivity; spectral theory; PDE; quantum mechanics;

   Abstract : This thesis investigates the distribution of superconductivity in a Type-II planar, bounded, and smooth superconductor submitted to a piecewise-constant magnetic field with a jump discontinuity along smooth curves---the magnetic edge. This discontinuous case has not been treated before in the mathematics literature, where the considered applied magnetic field is usually assumed to be smooth. READ MORE
