The Quark-meson model in a magnetic field
(Master thesis, 2017)In this thesis we study the chiral phase transition of two-flavor QCD, through the use of the quark-meson model. The effect of a magnetic field on the transition is studied, at finite temperature and baryon chemical ... -
Quasiclassical Theory for Dirac Material/Superconductor Proximity Structures
(Master thesis, 2016)In the decade since the experimental discovery of graphene and the topological insulators, the field of Dirac materials, a new class of materials with linear low-energy dispersions, has attracted great research interest. ... -
Robust Magnetic Surface Doping of Transition Metal Dichalcogenides
(Master thesis, 2016)The growth and potential intercalation of Fe on naturally grown MoS$_{2}$ has been studied using a number of surface techniques. An initial sample characterization revealed that samples extracted from the natural MoS$_{2}$ ... -
Room Geometries with non-classical Reverberation Times
(Master thesis, 2015)In this Master s thesis, it has been examined whether it is possible to find rooms of such a geometry that the reverberation time becomes shorter than the predicted value of Sabine and Eyring. This was investigated using ... -
Scanning Precession Electron Diffraction Study of 2xxx Series Aluminium Alloys Exhibiting Several Coexisting Strengthening Phases
(Master thesis, 2016)Throughout this thesis, scanning precession electron diffraction is applied to heat-treated Al-Cu-Li and Al-Mg-Cu-Ag alloys, shedding light on the distribution of phases present and the complex interplay between these ... -
Scattering of Electromagnetic Waves from Randomly Rough Surfaces with Skewed Height Distributions
(Master thesis, 2014)Research on the scattering of electromagnetic waves from rough surfaces has greatly advanced in the past decades through the access to rigorous numerical simulations. However, most of the research has focused on surfaces ... -
Schrödinger-Poisson and nonequilibrium Green's function methods applied to layered semiconductor devices
(Master thesis, 2018)In this work, electron transport through layered semiconductor heterostructure devices in the nanometer dimension are simulated. Because these devices have shrunk in the last decades, it is no longer sufficient to utilize ... -
Screening of a New Class of Fluorescent Probes for Diagnosis of Amyloid Deposits
(Master thesis, 2018)The purpose of this project has been to determine photo-physical properties of new and untested fluorescent probes. The probes have a 2,1,3-benzothiadiazole (BTD) ring structure and are derivatives of the previously explored ... -
Signatures of the Transition between Topologically and Magnetically Ordered Ground States in the Schwinger-Boson Mean Field Theory of Frustrated Quantum Antiferromagnets - An analysis of the triangular lattice Heisenberg model with nearest and next nearest neighbour interactions
(Master thesis, 2015)We present three different methods of finding the critical spin value $S_c$ of the quantum phase transition between the spin liquid and the Néel order phase on the mean field triangular Heisenberg antiferromagnet at $T=0$K. ... -
Simulation of Two-Phase Flow in Porous Media using a Network Model.
(Master thesis, 2016)A network simulator has been used to study two-phase flow in porous media. The medium has been modeled as a bundle of tubes and the capillary forces inside these tubes have been investigated. This has been done by applying ... -
Simulation of water self-diffusion in breast tissue
(Master thesis, 2018)Diffusion weighted magnetic resonance imaging (DW-MRI) can be used to distinguish malignant tumour tissue from benign lesions and healthy tissue. Although this is a well established clinical method, the detailed relationship ... -
Simulations and Measurements of Streamer discharges near Dielectrics
(Master thesis, 2017)A novel numerical fluid model for simulating streamer discharges has been tested and utilized with a two-diemnsional triple junction configuration. The triple junction was located at the upper end of a 1 cm dielectric rod, ... -
Simulations of Aluminum-Magnesium Alloys in a hexagonal close-packed Lattice based on the Cluster Expansion Method.
(Master thesis, 2018)By using the density-functional theory and adopting the approach of Kohn and Sham, together with the cluster expansion method for Monte Carlo simulations, aluminum-magnesium alloys on a hcp lattice have been studied. The ... -
Simulations of X-ray Propagation in Guiding Structures and Light Scattering From Coccoliths Using Finite Difference Methods
(Master thesis, 2017)This thesis consists of two major parts. First, future applications of waveguides in the X- ray regime has been studied numerically. The second part is devoted to the study of light scattering from calcite shells from ... -
Solar and Lunar Tides in the MLT
(Master thesis, 2016)Simulations were done in Matlab to see how many days of data is needed to get accurate values of solar and lunar semidiurnal tides amplitudes and phases. For the component dominating the signal, 4 days can be sufficient, ... -
