  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. Solving the Gleason Problem using Partition of Unity

    University essay from Mälardalens universitet/Akademin för utbildning, kultur och kommunikation

    Author : Amalia Adlerteg; [2023]
    Keywords : Gleason Problem; Partition of Unity;

    Abstract : The Gleason problem has been proven to be a complicated issue to tackle. In this thesiswe will conclude that a domain, Ω ⊂ R𝑛, has Gleason 𝑅-property at any point 𝑝∈ Ω, where 𝑅(Ω) ⊂ 𝐶∞(Ω) is the ring of functions that are real analytic in 𝑝. First, we investigate function spaces and give them fitting norms. READ MORE

  4. 3. 2d Gauge Theories

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Zhou Zheng; [2022]
    Keywords : ;

    Abstract : The Yang-Mills gauge theories play prominent role in modern high energy physics and the direct non-perturbative calculations present the main challenge in the field.Two dimensional gauge theories provide a nice playground where it is possible to carry out exact computations and at the same time some non-trivial phenomena canbe studied.

  5. 4. Fluxes from the reduction of a gauge theory on a squashed three-sphere

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Jim Lundin; [2021]
    Keywords : Supersymmetric Localization; Dimensional Reduction; Hopf fibration; Fluxes;

    Abstract : We present the supersymmetry and localization of an N=2 theory on S3b along with that of an N=(2,2) theory on S2. Performing the dimensional reduction of the theory on S3b produces a theory on S2 with no flux-sectors. READ MORE

  6. 5. Thermodynamical properties of cellular automata

    University essay from Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Author : Luca Bertolani; [2020]
    Keywords : Thermodynamics; Statistical; Mechanics; Cellular; automata; chaos; complex; matrix; computational; mathematical; 2d; two; dimensional; program; code; python; ising; teaching; ideal; gas; partition; function; equilibrium; non-equilibrium; classification; neighbourhood; local; Physics and Astronomy;

    Abstract : Cellular automata are a set of discrete computational models whose evolution is defined by neighbourhood rules and are used to simulate many complex systems in physics and science. In this work, statistical mechanics and thermodynamics in and out of equilibrium are used to develop a five-class classification scheme for two-dimensional cellular automata. READ MORE
