  1. 11. Creating Artificial Quantum Chiral States : Time Evolving Open Spin Chains

    University essay from Uppsala universitet/Materialteori

    Author : Emil Beiersdorf; [2023]
    Keywords : Quantum chirality; chirality; spin interaction; Heisenberg interaction; DM interaction; quantum physics; quantum mechanics; molecular nanomagnet; mathematical physics; theoretical physics; Kvantkiralitet; kiralitet; spinninteraktioner; Heisenberginteraktion; DMinteraktion; kvantfysik; kvantmekanik; molekylär nanomagnet; matematisk fysik; teoretisk fysik;

    Abstract : The discoveries in applications of chirality in various areas of science seem to never cease to emerge. Chirality, being the property that some objects are geometrically distinguishable from their mirror image, is a tiny difference of vast importance. READ MORE

  3. 12. Path Integrals in Quantum Mechanics and Low-Dimensional QFT

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Johanna Adbo; [2023]
    Keywords : QFT; path integrals; quantum mechanics; kvantfältteori; vägintegraler; kvantmekanik;

    Abstract : The focus of this thesis is to introduce the path integral and some of its applications. One interpretation of quantum mechanics is that a microscopic system which moves from an initial- to a final state moves through each possible intermediate state. READ MORE

  4. 13. Computational study of the photophysical properties of two related photosensitizer proteins

    University essay from KTH/Kemi

    Author : Benjamin Fégeant; [2023]
    Keywords : Photosensitizer proteins; QM MM; photophysics; molecular dynamics; computational protocol for protein preparation; Fotosensibiliserande proteiner; QM MM; fotofysik; molekylär dynamik; beräkningsprotokoll för förberedelser av proteiner;

    Abstract : Den ökande koldioxidhalten i atmosfären har lett till ett ökat intresse för användning av solljus, ett exempel är inom kemi. Att använda ljus i kemi kan leda till nya och intressanta kemiska reaktioner och kan tillämpas i användningsområden som exempelvis fotokatalys och fotovoltaik. READ MORE

  5. 14. Local Integrals of Motion from Neural Networks

    University essay from KTH/Fysik

    Author : Hannes Karlsson; [2023]
    Keywords : many-body localization; integrals of motion; neural networks; machine learning; flerkroppslokalisering; rörelseintegraler; neurala nätverk; maskininlärning;

    Abstract : Neural network quantum states (NNQS) is a novel machine learning method, based on restricted Boltzmann machines, previously used to represent the wave function in many-body quantum mechanics. In this thesis, we use NNQS to instead find integrals of motion, i.e., operators, commuting with the Hamiltonian, describing a system. READ MORE

  6. 15. Path integrals in Quantum Mechanics and their application to low-dimensional supersymmetry

    University essay from Uppsala universitet/Teoretisk fysik

    Author : Gaétan Kaouadji; [2023]
    Keywords : Path integrals quantum mechanics quantum field theory supersymmetry;

    Abstract : This report aims to give an insight to the path integral formalism in quantum mechanics. After explaining the kernel's construction, some of its properties and ways to compute it, we see how it relates to the Schrödinger picture. Moreover, we see how its representation can change if it is defined in the space, momentum, time or energy space. READ MORE
