  1. 1. Full Configuration Interaction Model for 1-D Quantum System

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

    Författare :Adam Asaad; [2022]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : The many-body problem is one of the most challenging problems in physics due to the complexity emerging from the interactions of many quantum particles. Since the advent of computers with increasing power, computational methods have been very successful in providing insight and precise solutions to this problem. LÄS MER

  2. 2. Non-perturbative models of diffractive hadronic collisions

    Kandidat-uppsats, Lunds universitet/Teoretisk partikelfysik

    Författare :Edgars Karnickis; [2022]
    Nyckelord :diffractive process; proton-proton collision; elastic; parton; PDF; saturation; Physics and Astronomy;

    Sammanfattning : In this thesis, a new model for diffractive proton-proton collisions is presented. Interpreting protons as systems of many partons, we treat diffraction in terms of elastic interactions between the partons of the colliding protons. LÄS MER

  3. 3. Competition between Phase Separation and Micellization in a Coarse-Grained Protein Model with Two Components

    Master-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik

    Författare :Fangxuan Lyu; [2022]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Intrinsically disordered proteins (IDPs) are widely believed to play a key role in the for- mation of intracellular biomolecular condensates through liquid-liquid phase separation (LLPS). Furthermore, it has been shown in vitro that several IDPs are able to phase sepa- rate on their own. LÄS MER

  4. 4. Evolutionary Properties of Neural Networks: Exploration of Robustness and Evolvability in the Genotype-Phenotype Map

    Master-uppsats, Lunds universitet/Beräkningsbiologi och biologisk fysik

    Författare :Daesung Cho; [2022]
    Nyckelord :robustness; evolvability; genotype-phenotype map; canalization; Bayesian inference; simulation-based inference; information theory; neural networks; pyloric rhythm; Physics and Astronomy;

    Sammanfattning : Evolution is a fundamental and crucial part of life that hinges on two central properties: robustness and evolvability. Robustness is required to maintain essential traits despite mutations while evolvability produces novel traits that might prove beneficial in survival. LÄS MER

  5. 5. Computational modelling of photosynthetic excitons coupled to a microcavity

    Master-uppsats, Lunds universitet/Institutionen för teoretisk fysik; Lunds universitet/Fysiska institutionen; Lunds universitet/Beräkningsbiologi och biologisk fysik; Lunds universitet/Institutionen för astronomi och teoretisk fysik

    Författare :Ilmari Turunen; [2022]
    Nyckelord :Cavity QED; LH2; Chlorophyll; Exciton; Polariton; Transition dipole moment; Absorbance; Physics and Astronomy; Chemistry; Biology and Life Sciences;

    Sammanfattning : Cavity quantum electrodynamics (QED) is a theory that is used for describing the interaction between matter and cavity modes. Not until relatively recently, cavity QED has been extended to the study of photosynthetic light-harvesting complexes (LHCs). LÄS MER
