  1. 1. Investigation of a newrepresentation of spin

    University essay from Uppsala universitet/Materialteori

    Author : Minna Palmgren Thun; [2023]
    Keywords : Material theory; Spin; Statistical physics; Second quantization; Materialteori; spinn;

    Abstract : 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

  3. 2. Student Intuitions in Statistical Mechanics

    University essay from Uppsala universitet/Fysikundervisningens didaktik

    Author : Ebba Koerfer; [2022]
    Keywords : Physics education research; statistical mechanics; student reasoning; microstates and macrostates; distinguishable and indistinguishable particles; Boltzmann distribution;

    Abstract : 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

  4. 3. Network Drone Control using Deep Reinforcement Learning

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Alex Hermansson Grobgeld; [2020]
    Keywords : ;

    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.

  5. 4. Non-Thermal Modeling Of Energy Propagation Carried By Phonons and Magnons

    University essay from

    Author : David Dahlgren; Amela Mehic; [2019]
    Keywords : phonon; magnon; Boltzmann transport equation; Heat transport; Atom;

    Abstract : 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

  6. 5. Probing the effect of dark matter velocity distributions on neutrino-based dark matter detection

    University essay from Uppsala universitet/Högenergifysik

    Author : Martin Ståhl; [2019]
    Keywords : Dark matter; WIMPs; velocity distribution; indirect detection;

    Abstract : 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
