  1. 1. Exact eigenstates of the Inozemtsev spin chain

    University essay from KTH/Fysik

    Author : Simon Lentz; [2021]
    Keywords : Theoretical physics; Mathematical physics; quantum mechanics; many-body problems; spin chain; Inozemtsev; Calogero-Sutherland; Teoretisk fysik; Matematisk fysik; kvantmekanik; mångpartikel problem; spinnkedjor; Inozemtsev; Calogero-Sutherland;

    Abstract : This thesis deals with the following question: are there more eigenfunctions, other than the already known eigenfunctions, of the spin chain with elliptic interactions known as the Inozemtsev spin chain? The Inozemtsev spin chain interpolates between two quantum integrable spin chains, theHeisenberg spin chain and the Haldane-Shastry spin chain. Therefore it is interesting to explore eigenfunctions of the Inozemtsev spin chain in greater detail. READ MORE

  3. 2. Deriving the shape of the surface from its Gaussian curvature

    University essay from KTH/Skolan för teknikvetenskap (SCI)

    Author : Lentz Simon; Felix Erksell; [2019]
    Keywords : ;

    Abstract : A global statement about a compact surface with constant Gaussian curvature is derived by elementary differential geometry methods. Surfaces and curves embedded in three-dimensional Euclidian space are introduced, as well as several key properties such as the tangent plane, the first and second fundamental form, and the Weingarten map.
