2. 1. Analyticity, Necessity and Belief : Aspects of two-dimensional semantics

   Author : Eric Johannesson; Peter Pagin; Dag Westerståhl; Graeme Forbes; Stockholms universitet; []
   Keywords : HUMANIORA; HUMANITIES; two-dimensional semantics; quantified modal logic; propositional attitudes; belief ascriptions; Kripke; descriptivism; necessity; apriority; analyticity; Theoretical Philosophy; teoretisk filosofi;

   Abstract : A glass couldn't contain water unless it contained H2O-molecules. Likewise, a man couldn't be a bachelor unless he was unmarried. Now, the latter is what we would call a conceptual or analytical truth. It's also what we would call a priori. READ MORE

4. 2. Resonant Inelastic X-ray Scattering Studies on Quasi-Two-Dimensional Superconducting Materials

   Author : Deepak John Mukkattukavil; Jan-Erik Rubensson; Marcus Agåker; Yasmine Sassa; Conny Såthe; Balasubramanian Thiagarajan; Uppsala universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Resonant inelastic x-ray scattering; Superconductivity; Crystal; Magnon; Phonon; Physics with spec. in Atomic; Molecular and Condensed Matter Physics; Fysik med inriktning mot atom- molekyl- och kondenserande materiens fysik;

   Abstract : Unconventional superconductivity is one of the many fascinating research areas of condensed matter physics. Understanding the superconducting pairing mechanism and its connection with other competing states remains unclear. READ MORE

7. 5. On the role of the electron-electron interaction in two-dimensional quantum dots and rings

   Author : Erik Waltersson; Eva Lindroth; Stephanie Reimann; Stockholms universitet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; quantum dot; quantum ring; quantum dot molecule; electronic structure; two-dimensional; many-body physics; many-body perturbation theory; coupled cluster; coupled cluster singles and doubles; quantum logical gates; quantum computing; quantum control; quantum control algorithm; Electronic structure; Elektronstruktur; fysik; Physics;

   Abstract : Many-Body Perturbation Theory is put to test as a method for reliable calculations of the electron-electron interaction in two-dimensional quantum dots. We show that second order correlation gives qualitative agreement with experiments on a level which was not found within the Hartree-Fock description. READ MORE
