  1. 1. Robust non-Abelian geometric phases on three-qubit spin codes

    Master-uppsats, Uppsala universitet/Materialteori

    Författare :Parham Azish; [2024]
    Nyckelord :Quantum information theory; Holonomic quantum computing; non-abelian systems;

    Sammanfattning : Quantum holonomies are non-Abelian Geometric Phases predominantly observed in adiabatic, non-adiabatic, or measurement-based quantum evolutions. Their significance lies in their potential utility within quantum computing due to their robustness against noise throughout the parameter path. LÄS MER

  3. 2. Representations of Three-Body Interactions In Physics

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

    Författare :Joel Johansen; [2023]
    Nyckelord :Three-Body Interactions; Two-Body Interactions; Physics and Astronomy;

    Sammanfattning : The thesis explores an already developed symmetry adapted representation of a two-body interaction with the main goal of extending the method to also include three-body interactions. The method considers a space of shifted one dimensional Gaussian particle densities which are used, together with their corresponding Hartree potentials, to define the respective collective subspaces in which the interactions are expanded.

  4. 3. Black Hole Dynamics in Stellar Clusters

    Master-uppsats, Lunds universitet/Institutionen för astronomi och teoretisk fysik - Genomgår omorganisation; Lunds universitet/Astronomi - Genomgår omorganisation

    Författare :Markus Strickert; [2022]
    Nyckelord :Black Holes; Globular Clusters; Dynamics; Intermediate-mass black holes; Simulations; Physics and Astronomy;

    Sammanfattning : Star clusters can harbour many exotic objects, including black holes (BHs), X-ray binaries and blue straggler stars. In dense stellar environments like globular clusters (GCs), two-body relaxation drives their dynamical evolution, where gravitational interactions between stars strive to equalize their kinetic energy in the cluster.

  5. 4. Abrasionsmekanismer i labtest och fält : Utvärdering av metoder för nötningsprovning av spetsar till pinnkultivatorer

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Clara Landström; [2022]
    Nyckelord :tribologi; materialvetenskap; abrasiv nötning;

    Sammanfattning : In this master thesis two simplified and small-scale methods for two-body and three-body abrasive wear were examined. It was examined how representative the methods were compared to field-tested points in a cultivator for agriculture. A total of six points with different compositions were tested and ranked based on the test results. LÄS MER

  7. 5. Finite temperature effects on decay rates in the real-time formalism

    Master-uppsats, Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Torbjörn Lundberg; [2020]
    Nyckelord :finite; temperature; effect; decay; rate; real; imaginary; time; formalism; real-time; imaginary-time; two-body; neutral; pseudoscalar; scalar; charge; spin-1 2; fermions; thermal; quantum; field; theory; equilibrium; Physics and Astronomy;

    Sammanfattning : This thesis work presents thermal decay rates for several reactions calculated within the framework of the real-time formalism. Processes considered are those of a neutral (pseudo)scalar decaying into two distinct (pseudo)scalars or into a fermion-antifermion pair. LÄS MER
