  1. 1. Topological Band Theory, An Overview

    Master-uppsats, Göteborgs universitet / Institutionen för fysik

    Författare :Jens Roderus; [2021-06-14]
    Nyckelord :;

    Sammanfattning : Topological insulators, superconductors and semi-metals are states of ma er with unique features such as quantized macroscopic observables and robust, gapless edge states. ese states can not be explainedby standard quantum mechanics, but require also the framework of topology to be properly characterized.

  2. 2. On Collapse

    Master-uppsats, Konstfack/Textil

    Författare :Lea Constan; [2021]
    Nyckelord :weaving; feminism; quantum physics; post-colonialism; immigration; globalism; power structures; asymmetry; light; darkness; collapse; haptic;

    Sammanfattning : This project is an active exploration of subjectivities through the medium of weaving. In a narrative illustrated with woven works, the emotional trajectory of this person of mixed cultural background through Swedish society is described. LÄS MER

  3. 3. Quantum thermodynamics explorations with a Hubbard-Holstein dimer

    Kandidat-uppsats, Lunds universitet/Matematisk fysik; Lunds universitet/Fysiska institutionen

    Författare :Emil Adam Jonatan Östberg; [2021]
    Nyckelord :QTD Quantum Thermodynamics Hubbard-Holstein Hubbard Holstein dimer Lanczos Suzuki-Trotter ST Exact diagonalization ED Hysteresis Path dependence Battery Mott-insulator; Physics and Astronomy;

    Sammanfattning : The goal of this project is to characterize the quantum thermodynamics of a Hubbard-Holstein dimer. We explore how the standard formalism of quantum thermodynamics behaves in the context many-body physics. LÄS MER

  4. 4. Exact eigenstates of the Inozemtsev spin chain

    Master-uppsats, KTH/Fysik

    Författare :Simon Lentz; [2021]
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  5. 5. Low-dimensional Magnetism in Novel 2D Honeycomb Materials

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Sebastian Johnsen; [2021]
    Nyckelord :Applied physics; Materials physics; Quantum materials; Magnetism; Muons; Neutrons; Tillämpad fysik; Materialfysik; Kvantmaterial; Magnetism; Myoner; Neutroner;

    Sammanfattning : A Kitaev quantum spin liquid is a phase of matter predicted to host excitations that can be used to preform fault-tolerant quantum computation. Though the theoretical prediction of such a state is on firm footing, its realisation in real materials has proven to be elusive. LÄS MER
