  1. 1. Crosscap States in Integrable Spin Chains

    Master-uppsats, KTH/Fysik

    Författare :Christopher Ekman; [2022]
    Nyckelord :Theoretical Physics; Mathematical Physics; Integrability; Integrable Systems; Spin chains; Heisenberg model; Integrable Boundary States; Crosscap states; Teoretisk fysik; Matematisk fysik; Integrabilitet; Integrabla system; Spinnkedjor; Heisenbergmodellen; Integrabla gränstillstånd; Crosscaptillstånd;

    Sammanfattning : We consider integrable boundary states in the Heisenberg model. We begin by reviewing the algebraic Bethe Ansatz as well as integrable boundary states in spin chains. Then a new class of integrable states that was introduced last year by Caetano and Komatsu is described and expanded. We call these states the crosscap states. LÄS MER

  2. 2. Uppgifter om elektriska kretsar : Testar svenska fysiklärare rätt typ av kunskaper?

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Fysikundervisningens didaktik

    Författare :Kajsa Fransson; [2022]
    Nyckelord :Physics education; electrical circuits; tests; Fysikundervisning; elektriska kretsar; prov;

    Sammanfattning : The purpose of this physics didactics work is to contribute to an increased knowledge of learning about electrical circuits. This is done partly through a literature studyof students’ difficulties, but also through an examination of test items on electrical circuits used in the Swedish upper secondary school. LÄS MER

  3. 3. Non-perturbative models of diffractive hadronic collisions

    Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik

    Författare :Edgars Karnickis; [2022]
    Nyckelord :diffractive process; proton-proton collision; elastic; parton; PDF; saturation; Physics and Astronomy;

    Sammanfattning : In this thesis, a new model for diffractive proton-proton collisions is presented. Interpreting protons as systems of many partons, we treat diffraction in terms of elastic interactions between the partons of the colliding protons. LÄS MER

  4. 4. Adaption of Inertial Confinement Fusion Resultsto Spherical Plasma Expansion at Comets

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi; Uppsala universitet/Institutet för rymdfysik, Uppsalaavdelningen

    Författare :Viktor Sparrman; [2022]
    Nyckelord :Plasma; Inertial confinement fusion; comet; plasma expansion; Vlasov-Poisson; integral invariants; ergodicity;

    Sammanfattning : Recent missions to solar system comets, such as ESA's Rosetta mission, raise interest for models and descriptions of their plasma environment. The interaction with various space phenomena such as stellar wind make the construction of an analytical description difficult. LÄS MER

  5. 5. X-Ray Fluorescence of Metal Halide Perovskites

    Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Samuel Narciso Silva; [2022]
    Nyckelord :Perovskite; X-ray; Fluorescence; Python; PyMCA; Synchrotron radiation; Physics and Astronomy;

    Sammanfattning : This thesis has the aim to provide a framework for analyzing X-ray fluorescence (XRF) data obtained from German Electron-Synchrotron Group (DESY). The theoretical analysis shows that XRF competes with Auger emission, and works mainly for elements with high atomic number. Here, incident X-rays of 13. LÄS MER
