1. 1. Magnetic field of the magnetic chemically peculiar star V1148 Ori

   University essay from Uppsala universitet/Institutionen för fysik och astronomi

   Author : Kristoffer Pettersson; [2023]
   Keywords : chemically peculiar star; magnetic fields; deconvolution; zeeman effect; polarization;

   Abstract : This project aims to obtain and interpret the measurements of the mean longitudinal magnetic field of the chemically peculiar star V1148 Ori. To achieve this aim 12 spectropolarimetric observations obtained by the CFHT using the spectropolarimeter ESPaDOnS were used. READ MORE

3. 2. Three-body decay as a baryon polarizer

   University essay from Uppsala universitet/Kärnfysik

   Author : Carl Johan Königsson; [2023]
   Keywords : Three-body decay; polarization; CP violation; hyperon; resonance; Trekroppssönderfall; polarisation; CP-brytning; hyperon; resonans;

   Abstract : According to the standard model, the size of CP violation in the weak decay Λ → pπ- is predicted to be ∼ 10-5. This means that a very high precision is needed if we want to be able to measure it. READ MORE

4. 3. Petrophysical Properties of Rocks in Central Kiruna Mining District, Sweden

   University essay from Uppsala universitet/Institutionen för geovetenskaper

   Author : Simon Peter Dagbui; [2023]
   Keywords : Kiruna mining district; Common earth model; petrophysics; density; AMS; complex electrical resistivity; NRM; magnetization; IOA; Kirunavaara Mineralization;

   Abstract : High economic and metallogenic significance of northern Norrbotten ore district in Sweden which hosts Kiruna mining district makes it a very important ore district in the world. Northern Norrbotten ore district contributes a combined 90 percent of iron production in Europe. READ MORE

5. 4. Numerical simulations of ultrafast dynamics in plasmonic nanostructures

   University essay from Umeå universitet/Institutionen för fysik

   Author : Nils Henriksson; [2023]
   Keywords : Ultrafast nanophotonics; Three temperature model; Numerical simulations;

   Abstract : Plasmonic effects in nanosized particles enhance the interaction between light and matter due to the localized surface plasmon resonance, with potential applications such as all-optical transistors and optical computers. Commonly, the dynamics of nanoparticles’ optical properties are assessed via pump-probe spectroscopy, where a plasmonic structure is exited by an initial laser, the pump. READ MORE

6. 5. Improving polarizing neutron optics by introducing 11B4C as interlayers

   University essay from Linköpings universitet/Tunnfilmsfysik

   Author : Martin Falk; [2023]
   Keywords : Thin film multilayers; Neutron optics; Neutron polarization;

   Abstract : In this report, the effects of adding 11B4C as interlayers into Fe/Si multilayers is studied. Fe/Si multilayers are commonly used for neutron polarization at large research facilities, and improving the polarizing properties would improve their efficiency. READ MORE
