1. Investigation of a newrepresentation of spin
University essay from Uppsala universitet/MaterialteoriAbstract : The Bose-Hubbard Model, a tight binding model within solid state theory can be solved exactly using a number theoretical approach. From this approach, in the two sited Bose-Hubbard model, the hopping term in the model takes the form of a Pauli x matrix. The hopping term can be interpreted as a two energy level system or a dimer with k+1 particles. READ MORE

2. Student Intuitions in Statistical Mechanics
University essay from Uppsala universitet/Fysikundervisningens didaktikAbstract : This exploratory case study aimed to investigate patterns in student reasoning in statistical mechanics, in order to identify difficulties and develop ideas for future research. Upper-division undergraduate students, taking a course in statistical mechanics, were interviewed in groups. READ MORE

3. Network Drone Control using Deep Reinforcement Learning
University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)Abstract : In this work, a reinforcement learning approach is adopted to control a drone in a cellular network. The goal is to find paths between arbitrary locations such that low radio quality areas, defined with respect to signal-to-interference-plus-noise-ratio, are avoided with the cost of longer flight paths.

4. Non-Thermal Modeling Of Energy Propagation Carried By Phonons and Magnons
University essay fromAbstract : Heat transport by phonons and magnons in crystals due to a local perturbation in temperature is described by the Boltzmann transport equation. In this project a one phonon one magnon system was studied in a one dimensional rod with reflective boundaries. Using the splitting algorithm the problem was reduced to a transport and collision term. READ MORE

5. Probing the effect of dark matter velocity distributions on neutrino-based dark matter detection
University essay from Uppsala universitet/HögenergifysikAbstract : Dark matter has a long history, but it was not until modern times that we have a chance of detecting it. This thesis focuses on the velocity distribution and its effect on indirect WIMP detection. Recently a new velocity distribution, based on data from SDSS and GAIA, was proposed. READ MORE
