1. 1. Investigation of a newrepresentation of spin

   Kandidat-uppsats, Uppsala universitet/Materialteori

   Författare :Minna Palmgren Thun; [2023]
   Nyckelord :Material theory; Spin; Statistical physics; Second quantization; Materialteori; spinn;

   Sammanfattning : The Bose-Hubbard Model, a tight binding model within solid state theory can be solved exactly using a number theoretical approach. From this approach, in the two sited Bose-Hubbard model, the hopping term in the model takes the form of a Pauli x matrix. The hopping term can be interpreted as a two energy level system or a dimer with k+1 particles. LÄS MER

3. 2. The Stern-Gerlach Spectrometer for Charged Particles : A step towards an alternative method for measuring spin

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

   Författare :Samuel Eriksson; [2023]
   Nyckelord :Stern-Gerlach; Stern; Gerlach; spin; time-of-flight; time of flight; magnetic moment; spectrometer; Physics and Astronomy;

   Sammanfattning : The purpose of this project is to investigate the performance of a spectrometer capable of measuring both momentum and spin of particles. More specifically, we investigated what parameters are required in order to separate particles with opposite spins at least 1 mm. LÄS MER

4. 3. CHARACTERIZATION AND EVALUATION OF A NIPAM POLYMER GEL MRI DOSIMETER SYSTEM

   Master-uppsats,

   Författare :Christian Waldenberg; [2022-11-08]
   Nyckelord :Medical physics; Normoxic polymer gel dosimeter; NiPAM;

   Sammanfattning : Purpose: The normoxic polymer gel dosimeter based on N-isopropyl acrylamide (NiPAM) is a promising full 3D-dosimeter with high spatial resolution and near tissue equivalency. However, limited work have been done in vestigating this dosimeter. The dose response and reproducibility of a NiPAM dosimeter was investigated. LÄS MER

5. 4. Development of an event generator for antihyperon-hyperon pair production in antiproton-proton collisions

   Master-uppsats, Uppsala universitet/Kärnfysik

   Författare :Vitor Jose Shen; [2022]
   Nyckelord :MC event generator; Antihyperon-hyperon pair; Antiproton-proton collisions; PANDA; ROOT; 4-vector kinematics; Angular distribution;

   Sammanfattning : The goal of this project was to develop a lightweight Monte-Carlo (MC) event generator for hyperon pair production in antiproton-proton collisions, and demonstrate it in one of the hyperon decay reaction channels, which is collisions of proton and antiproton to lambda hyperon and anti-lambda hyperon, and they decay to antiproton-positive pion pair, and proton-negative pion pair. The prototype of this external MC event generator we presented here is based on the software framework of ROOT. LÄS MER

7. 5. Student Intuitions in Statistical Mechanics

   L3-uppsats, Uppsala universitet/Fysikundervisningens didaktik

   Författare :Ebba Koerfer; [2022]
   Nyckelord :Physics education research; statistical mechanics; student reasoning; microstates and macrostates; distinguishable and indistinguishable particles; Boltzmann distribution;

   Sammanfattning : This exploratory case study aimed to investigate patterns in student reasoning in statistical mechanics, in order to identify difficulties and develop ideas for future research. Upper-division undergraduate students, taking a course in statistical mechanics, were interviewed in groups. LÄS MER
