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

    University essay from KTH/Fysik

    Author : Christoffer Beiming; [2023]
    Keywords : 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;

    Abstract : 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. READ MORE

  3. 12. An alternative explanation for scale-free speed correlations in starling flocks: coarse-graining in time

    University essay from Linnéuniversitetet/Institutionen för fysik och elektroteknik (IFE)

    Author : Mate Jagnjic; [2023]
    Keywords : scale-free correlations; active matter; starling flocks; coarse-graining;

    Abstract : In a celebrated series of experimental observations, starling flocks have been shown to be characterized by scale-free, long-ranged spatial correlations in their velocity fluctuations. While this is expected for velocity orientation correlations on the basis of simple symmetry-breaking arguments, the same scaling-free behaviour for speed (i.e. READ MORE

  4. 13. Study of Triply Periodic Minimal Surfaces for Heat Transfer Applications

    University essay from Uppsala universitet/Institutionen för materialvetenskap

    Author : María Xuan Celaya Granados; [2023]
    Keywords : ;

    Abstract : In the pursuit of enhancing heat exchanger efficiency, several heat transfer- enhancing strategies are employed. The traditional methods include surface vibrations, microchannels, and integration of vortex generators. Additionally, new solutions are being studied, taking advantage of other relevant improve- ments in the engineering field. READ MORE

  5. 14. Studies of the axial-vector transition form factors of the process Ω− → W−Ξ0 in chiral perturbation theory

    University essay from Uppsala universitet/Kärnfysik

    Author : Hélène De Munck; [2023]
    Keywords : Transition form Factors; Next-to-next-to-leading order; chiral perturbation theory; axial-vector; Ω− → W−Ξ0;

    Abstract : This work is included in a broader research of the hadron theory group of Uppsala University and its collaborators tackling the quest for an understanding of the quark distribution inside hadrons by joining threedifferent approaches of QCD namely chiral perturbation theory, dispersion theory and lattice QCD. This thesis contributes by computing in chiral perturbation theory, the quark-masses dependence of form factors. READ MORE

  6. 15. A Side-Channel Attack on Masked and Shuffled Implementations of M-LWE and M-LWR Cryptography : A case study of Kyber and Saber

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Linus Backlund; [2023]
    Keywords : Public-key Cryptography; Post-Quantum Cryptography; Kyber; Saber; Side-Channel Attack; Power Analysis; Asymetrisk Kryptering; Kvantsäker Kryptografi; Kyber; Saber; Sidokanalsattack; Effektanalys;

    Abstract : In response to the threat of a future, large-scale, quantum computer, the American National Institute of Standards and Technology (NIST) initiated a competition for designs of quantum-resistant cryptographic primitives. In 2022, the lattice-based Module-Learning With Errors (M-LWE) scheme Kyber emerged as the winner to be standardized. READ MORE
