1. 6. Quantum Computing in Nuclear Physics

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

   Författare :Luca Bernecker; [2022]
   Nyckelord :quantum computing; nuclear physics; qubits; theoretical physics; Physics and Astronomy;

   Sammanfattning : In this thesis, we investigate many–body systems using simulations of quan- tum computers. Quantum computing is a computational paradigm based on qubits which are defined in a Hilbert space instead of the familiar binary bits. LÄS MER

3. 7. Geometry studies of high energy 16O collisions

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

   Författare :Aliaksei Kuzmenka; [2022]
   Nyckelord :Ion Collisions; Oxygen; Physics and Astronomy;

   Sammanfattning : In this project a model of oxygen, 16O, nuclei, where the nucleons are organised in α-clusters, was implemented in the Pythia Monte Carlo event generator. To study the effects of the new model, some observables, such as the distribution of the number of the wounded nucleons, charged particle multiplicity in the forward and central pseudorapidity region, and the pseudorapidity distribution for different centrality bins and eccentricity, are compared to the model originally implemented in Pythia (Woods-Saxon).

4. 8. Cosmological implications of a QCD-like composite Higgs model

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

   Författare :Hristina Georgieva Hristova; [2021]
   Nyckelord :composite Higgs; technicolor; gravitational waves; LISA; phase transition; Physics and Astronomy;

   Sammanfattning : Some of the shortcomings of the Standard Model of particle physics are the 'unnatural' value of the mass of the Higgs boson and the fact that the model cannot account for the process of baryogenesis - a mechanism which generates the observed asymmetry between matter and anti-matter in the Universe. The former is related to the fundamental scalar nature of the Higgs boson, connected to quadratic divergences in the mass corrections. LÄS MER

5. 9. A Program for SU(N) Color Structure Decomposition into Multiplet Bases Using Wigner 3j and 6j Coefficients

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

   Författare :Andris Potrebko; [2020]
   Nyckelord :Colour Structure; QCD; Quantum Chromodynamics; SU N ; Multiplet bases; Color structures; Physics and Astronomy;

   Sammanfattning : The increased capacity of elementary particle accelerators raises the demand for the simulation data of the experiments. One of the bottlenecks in the simulations is the QCD color structure calculation, which is usually treated using non-orthogonal and overcomplete sets of bases. LÄS MER

7. 10. QFT and Spontaneous Symmetry Breaking

   Kandidat-uppsats, Uppsala universitet/Teoretisk fysik

   Författare :Sheila Chauwinoir; [2020]
   Nyckelord :quantum field theory; abelian and non-abelian gauge theories; quantum electrodynamics; quantum chromodynamics; electroweak interaction; spontaneous symmetry breaking; higgs mechanism;

   Sammanfattning : The aim of this project is to understand the structure of the Standard Model of the particle physics. Therefore quantum field theories (QFT) are studied in the both cases of abelian and non-abelian gauge theories i.e. quantum electrodynamics (QED), quantum chromodynamics (QCD) and electroweak interaction are reviewed.
