  1. 1. Effects of Ultrafast Ionization in X-ray Coherent Diffraction Imaging

    Master-uppsats, KTH/Kemi

    Författare :Arezu Sehati; [2023]
    Nyckelord :Coherent Diffraction Imaging; X-ray Free Electron Lasers; Refractive index; Core-shell nanoclusters; Rare-gas ionization; Koherent Diffraktionsavbildning; Röntgenfrielektronlaser; Brytningsindex; Core-shell-nanokluster; Ädelgasjonisering;

    Sammanfattning : Koherent Diffraktionsavbildning med en intensiv röntgenpuls från en Frielektronlaser har möjliggjort strukturbestämning av isolerade nanopartiklar som inte går att studera med hjälp av konventionella metoder, så som elektronmikroskopi. En mycket kort pulslängd tillsammans med spridningssignalens beroende av objektets elektroniska struktur medför också möjligheten att studera inducerad ultrasnabb dynamik med denna teknik. LÄS MER

  3. 2. THE COUPLING OF A DOUBLE QUANTUM DOT TO MICROWAVE PHOTONS

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

    Författare :Mohamed Abrash; [2023]
    Nyckelord :Quantum computing; Qubit; Double quantum dot DQD ; Microwave resonator; Quantum integrated circuits; Sweet spots; Hybrid quantum circuits.; Physics and Astronomy;

    Sammanfattning : In this study, we derive a mathematical description of a double quantum dot (DQD) embedded in a microwave resonator starting from classical electrostatics. DQDs are a promising platform for building quantum computers and have important applications in quantum sensing and the study of light-matter interactions. LÄS MER

  4. 3. Three-body decay as a baryon polarizer

    Kandidat-uppsats, Uppsala universitet/Kärnfysik

    Författare :Carl Johan Königsson; [2023]
    Nyckelord :Three-body decay; polarization; CP violation; hyperon; resonance; Trekroppssönderfall; polarisation; CP-brytning; hyperon; resonans;

    Sammanfattning : According to the standard model, the size of CP violation in the weak decay Λ → pπ- is predicted to be ∼ 10-5. This means that a very high precision is needed if we want to be able to measure it. LÄS MER

  5. 4. Numerical simulations of ultrafast dynamics in plasmonic nanostructures

    Uppsats för yrkesexamina på avancerad nivå, Umeå universitet/Institutionen för fysik

    Författare :Nils Henriksson; [2023]
    Nyckelord :Ultrafast nanophotonics; Three temperature model; Numerical simulations;

    Sammanfattning : Plasmonic effects in nanosized particles enhance the interaction between light and matter due to the localized surface plasmon resonance, with potential applications such as all-optical transistors and optical computers. Commonly, the dynamics of nanoparticles’ optical properties are assessed via pump-probe spectroscopy, where a plasmonic structure is exited by an initial laser, the pump. LÄS MER

  7. 5. Governed to be cancelled : The qualitative aspects of cancel culture's governmentality, focusing on its impact beyond the individual perpetrator.

    Master-uppsats, Jönköping University/HLK, Medie- och kommunikationsvetenskap

    Författare :Hasib Zolic; [2023]
    Nyckelord :Cancel culture; Governmentality; Parasocial relationship; Hip-hop; MCDA;

    Sammanfattning : This thesis explores the phenomenon of cancel culture within the media and communication science field, aiming to contribute to the understanding of cancel culture beyond the focal point of the cancelled figure. Drawing upon the theoretical framework of Governmentality with discourse and language and utilizing Multimodal Discourse Analysis (MCDA) as a methodological tool, the study delves into the complexities of cancel culture and its implications.
