1. Flow of charged particles in Pb-Pb and pp collisions at the LHC
Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysikSammanfattning : This thesis investigates the transition of Quantum Chromodynamic (QCD) matter to a strongly interacting Quark Gluon Plasma (QGP), where quarks and gluons become deconfined. The expansion of this plasma exhibits characteristics of an ideal relativistic hydrodynamics system, suggesting a behavior similar to that of a perfect fluid. LÄS MER
2. Localized and extended states in finite-sized mosaic Wannier-Stark lattices
Master-uppsats, KTH/Tillämpad fysikSammanfattning : Anderson localization occurs when an otherwise conductive solid becomes insulatingdue to a sufficiently large degree of disorder in the medium. The electron band energy(as a function of disorder) at which this transition between extended and localizedelectron states occur is called the mobility edge (ME) and is energy-dependent only in3-dimensional systems.

3. Probing Charm Production with Three-Particle Correlations in pp Collisions
Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Partikel- och kärnfysikSammanfattning : This thesis aims to investigate possible correlations between charm production and baryon production in proton-proton collisions through three-particle correlations. The question attempted to be answered is where, for a given charmed baryon, the balancing anti-charm particle and balancing anti-baryon are located. LÄS MER
4. Local Integrals of Motion from Neural Networks
Master-uppsats, KTH/FysikSammanfattning : Neural network quantum states (NNQS) is a novel machine learning method, based on restricted Boltzmann machines, previously used to represent the wave function in many-body quantum mechanics. In this thesis, we use NNQS to instead find integrals of motion, i.e., operators, commuting with the Hamiltonian, describing a system. LÄS MER
5. LBIC Measurements on Busbarless Crystalline Silicon Solar Cells
Kandidat-uppsats, Karlstads universitet/Institutionen för ingenjörsvetenskap och fysik (from 2013)Sammanfattning : The importance of further research in the field of solar cells is crucial for the transition to cleaner energy. The aim of this project is to design and manufacture a contact system that can measure busbarless solar cells with an LBIC-system. LÄS MER
