  1. 1. Kvantdynamik hos NaI-molekylexciterad av ultrasnabbfemtosekundslaserpuls : Numerisk lösning av den explicit tidsberoendeSchrödingerekvationen

    Kandidat-uppsats, Uppsala universitet/Institutionen för informationsteknologi

    Författare :Anna Johansson; Josefine Hörnell; Liza Marshah; [2023]
    Nyckelord :beräkningsvetenskap; femtosekunds laserpuls; kvantkemi; diatom modell; diabatisk system; Schrödingerekvationen; NaI;

    Sammanfattning : Detta projekt fokuserar på att undersöka dynamiken hos partiklar inom en-partikelsystem samt sammankopplade partiklar i tvåpartikelsystem genom tillämpning av numeriska metoder. Tvåpartikelsystemet som studeras är NaI-molekylen och dess dynamik, där beteendet undersöks efter systemet utsatts för en femtosekundslaserpuls. LÄS MER

  3. 2. On the (1/2,1/2) Representation of the Lorentz Group and the Discrete CPT Symmetries

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

    Författare :Nikolaj Skog Pirinen; [2021]
    Nyckelord :The Lorentz Group; Group Theory; Quantum Field Theory; CPT; Symmetry; Spinors; Representation Theory; Physics and Astronomy;

    Sammanfattning : This thesis derives the explicit form of the elements of the (1/2,1/2) representation of the Lorentz group, by actually performing a direct product of the chiral (1/2,0)- and (0,1/2)-representations. The Lorentz transformations of fourvectors are thereafter recovered from this direct-product representation, allowing the derivation of a transformation matrix between the fourvector- and direct product basis.

  4. 3. Constructing Numerical Methods For Solving The Guiding Equation In Bohmian Mechanics

    Master-uppsats, Uppsala universitet/Materialteori

    Författare :Nilsson Robert; [2021]
    Nyckelord :Bohmian mechanics; De Broglie Bohm Theory; Numerical Methods;

    Sammanfattning : The aim of this thesis was to simulate a part of a proposed experiment by Lev Vaidman by using Bohmian mechanics. To do this a numerical method for solving the Schrödinger equation and theguiding equation was created, with several ways of making the simulation more efficient. LÄS MER

  5. 4. A Non-Relativistic Model of Tetraquarks

    Kandidat-uppsats, KTH/Skolan för teknikvetenskap (SCI)

    Författare :Per Lundhammar; [2020]
    Nyckelord :;

    Sammanfattning : In this thesis, a non-relativistic model of tetraquark in a diquark-antidiquark configuration is investigated. Using a variation of the Cornell potential, the Schrödinger equation is solved numerically, and the four-body problem of the tetraquark is separated into to three two-body problems. LÄS MER

  7. 5. Comparative Analysis of Adaptive Domain Decomposition Algorithms for a Time-Spectral Method

    Master-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Vilhelm Dinevik; [2020]
    Nyckelord :;

    Sammanfattning : Time-spectral solvers for partial differential equations (PDE) have been explored in various forms during the last few decades. The generalized weighted residual method (GWRM) is one such method with a high accuracy and efficiency. The GWRM has so far been implemented almost exclusively with a uniform grid of subdomains in the spatial domain. LÄS MER
