1. 1. Numerical Estimation of Critical Exponents in the 3D XY Model

   Master-uppsats, KTH/Fysik

   Författare :Christoffer Beiming; [2023]
   Nyckelord :Theoretical physics; Condensed matter theory; Phase transitions; XY model; Critical exponents; Computational physics; Monte Carlo simulations; Teoretisk fysik; Kondenserade materiens teori; Fasövergångar; XY-modellen; Kritiska exponenter; Beräkningsfysik; Monte Carlo simulering;

   Sammanfattning : The experimentally obtained value of the critical exponent ν is presently in significant disagreement with current theoretical predictions for the λ-universality class. We suggest two novel approaches of determining the exponents ν and η by utilizing the effects of finite size scaling. LÄS MER

3. 2. Renormalization group approach to statistical systems

   Kandidat-uppsats, Uppsala universitet/Teoretisk fysik

   Författare :Patrik Lidén; [2015]
   Nyckelord :;

   Sammanfattning : This report will study the theory of renormalization group used on a ferromagnet to calculate magnetic phase transitions. As the ferromagnet's temperature changes, so does interatomic interaction, causing either a lingering magnetization at low temperatures, or a random state at high temperatures. LÄS MER
