  1. 1. The Ratio of Reality : A study of the gyromagnetic ratio in theories ranging from classical mechanics to string theory

    Kandidat-uppsats, Uppsala universitet/Teoretisk fysik

    Författare :Daniel Nilsson; [2021]
    Nyckelord : Quantum field theory ; String theory ; Dirac equation ; Dirac theory ; Dirac; gyromagnetic; ratio; g-factor; Kvantfältsteori; strängteori; Dirac; g-factor; gyrmagnetisk kvot ;

    Sammanfattning : In this project a theoretical study of the so called gyromagnetic ratio was done by investigating classical mechanics, Dirac theory and string theory. The gyromagnetic ratio is a constant term appearing in the coupling between angular momentum and magnetic moment for a particle. LÄS MER

  2. 2. Reversing the flow of heat in system of initially correlated qubits

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

    Författare :Giovanni Francesco Diotallevi; Peter Samuelsson; Faraj Bakhshinezhad; [2021]
    Nyckelord :Qubits; Cooling; Heat Flow; Physics and Astronomy;

    Sammanfattning : The Second Law of Thermodynamics is considered to be one of the most fundamental and important laws of Physics. Both Clausius and Kelvin reformulated the Second Law as statements concerning the behaviour of two communicating systems, set to interact at different temperatures. LÄS MER

  3. 3. Radiative Corrections Beyond the Soft-Photon Approximation

    Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik

    Författare :Jacob Lindahl; [2021]
    Nyckelord :Soft-Photon Approximation; Bremsstrahlung Correction; Transition Form Factor; Radiative Corrections; Physics and Astronomy;

    Sammanfattning : This thesis calculates the bremsstrahlung correction beyond the soft-photon approximation for the decay ω → π0 l+ l- . The effect of the radiative corrections on the extraction of the transition form factor from data is investigated. LÄS MER

  4. 4. Microscopic and Macroscopic Samples of Atoms in Superposition States Studied by Attosecond Pulses

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

    Författare :Axel Stenquist; [2021]
    Nyckelord :Mathematical physics; Theoretical physics; Atomic physics; Attosecond physics; Ultra-fast physics; Numerical simulations; Microscopic; Mesoscopic; Macroscopic; Superposition; Light matter interaction; Quantum mechanics; Electromagnetism; Semiclassical; Attosecond transient absorption spectroscopy; ATAS; Förster resonance; FRET; Two-atom model; Inter-atomic interaction; Dipole-dipole interaction; Many-atom model; Collective coherent effects; Time-dependent configuration-interaction singles; TDCIS; Physics and Astronomy;

    Sammanfattning : In the present thesis, the interaction between atoms in superposition states and attosecond pulses is studied from the microscopic to the macroscopic regime. Using a semi-classical framework, three different models have been explored in order to investigate attosecond light--matter interaction processes. LÄS MER

  5. 5. Simulations of fission fragments in VERDI : A study of the Plasma Delay Time phenomenon

    Kandidat-uppsats, Uppsala universitet/Tillämpad kärnfysik; Uppsala universitet/Tillämpad kärnfysik

    Författare :Lovisa Rygaard; Andreas Ström; [2020]
    Nyckelord :;

    Sammanfattning : The purpose of this project is to study the plasma delay time phenomenon in preparation for the construction of the VERDI spectrometer. To accomplish this, simulations of the spontaneous fissioning process of Cf-252 were created using the fission code GEF, as well as MATLAB. LÄS MER
