1. 1. Studies in Glacier Mass Balance : Measurement and its errors

   Författare :Andrew Mercer; Peter Jansson; Gunhild Rosqvist; Ian Brown; Jonathan Carrivick; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Glaciology; Mass Balance; Measurement Errors; Physical Geography; naturgeografi;

   Sammanfattning : The study of the surface mass balance of valley glaciers has a long history but one that is dogged by uncertainty and errors, and uncertainty about those errors. These problems are acknowledged by the glaciological community and have been examined and formalised in several publications. LÄS MER

3. 2. Computation of constraints in bimetric theory

   Författare :Anders Lundkvist; Fawad Hassan; Edwin Langmann; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; teoretisk fysik; Theoretical Physics;

   Sammanfattning : The Hassan-Rosen bimetric theory describes two interacting spin-2 fields, one massless and one massive. In this thesis, a complete canonical analysis of this theory is performed in the metric formulation and all constraints are computed. LÄS MER

4. 3. Amphiphilic Molecules in Aqueous Solution

   Författare :Gerd Persson; Göran Lindblom; Håkan Edlund; Björn Lindman; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Physical chemistry; liquid crystal; phase diagrams; counterions; alkylpyridinium octanesulfonates; 1-monooleoyl-rac-glycerol; n-octyl-β-D-glucoside; cubic phases; Fysikalisk kemi; Physical chemistry; Fysikalisk kemi; Physical Chemistry; fysikalisk kemi;

   Sammanfattning : The aim of this thesis was to investigate amphiphilic molecules in aqueous solution. The work was divided into two parts. In the first part the effects of different counterions on phase behavior was investigated, while the second part concerns the 1-monooleoyl-rac-glycerol (MO)/n-octyl-β-D-glucoside (OG)/2H2O-system.

5. 4. Holographic descriptions of collective modes in strongly correlated media

   Författare :Marcus Tornsö; Chalmers tekniska högskola; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; plasmonics; strongly correlated media; holography; gauge gravity duality; graphene; strong coupling; quasinormal modes;

   Sammanfattning : Solving the puzzle of high temperature superconductivity may be one of the most desired scientific breakthroughs of our time, as access to room temperature superconductivity could revolutionize society as we know it. In this thesis, we strive to increase the theoretical understanding of such matter, by studying the phase above, in temperature, the superconducting phase - the "strange metal". LÄS MER

7. 5. Atomistic simulations of structural and dynamical properties of liquids under geometric constraints

   Författare :Lorenzo Agosta; Alexander Lyubartsev; Marialore Sulpizi; Stockholms universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; liquid; contraint; TiO2; surfaces; bio-inorganic; molecular dynamic; ab-initio; tight-binding; DFT; metadynamic; free energy; nanoparticles; water; amino acids; adsorption; mesophases; hexatic; smectic; triply periodic network; Fddd; fysikalisk kemi; Physical Chemistry;

   Sammanfattning : The statistical-mechanical description of liquids represents a formidable problem in physic due to the absence of the analytical theory of the liquid state. Atomistic simulations represent a unique source of information in this respect and can be implemented in order address macroscopically measurable liquid properties, including its structure and dynamics, based on the information of the interactions between its constituent molecules.
