  1. 1. Impact of nitrogen availability and nitrogen structural composition on fungal enzymatic activity and growth : how nutrient availability governs response and development of three saprotrophic Basidiomycetes

    Master-uppsats, SLU/Dept. of Soil and Environment

    Författare :Bella Strid; [2024]
    Nyckelord :nitrogen; tannins; condensed tannins; MnP; manganese peroxidase; peptidase; saprotrophic basidiomycetes;

    Sammanfattning : Fungi excrete a wide variety of extracellular enzymes to scavenge for nutrients, such as the often scarce yet essential nutrient nitrogen. All fungi produce highly specialized hydrolytic enzymes, e.g. peptidases, that depolymerize organic molecules. LÄS MER

  3. 2. Localized and extended states in finite-sized mosaic Wannier-Stark lattices

    Master-uppsats, KTH/Tillämpad fysik

    Författare :Emrah Tortumlu; [2023]
    Nyckelord :Applied Physics; Condensed matter physics; quantum technology; quantum nanophotonics; localization; mobility edge; phase transition; Tillämpad Fysik; Kondenserade materiens fysik; kvantteknologi; kvantnanofotonik; lokalisering; fasövergång;

    Sammanfattning : Anderson localization occurs when an otherwise conductive solid becomes insulatingdue to a sufficiently large degree of disorder in the medium. The electron band energy(as a function of disorder) at which this transition between extended and localizedelectron states occur is called the mobility edge (ME) and is energy-dependent only in3-dimensional systems.

  4. 3. Majorana bound states in chains of interacting quantum dots

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen; Lunds universitet/NanoLund: Centre for Nanoscience

    Författare :William Samuelson; [2023]
    Nyckelord :quantum dots; superconducting proximity effect; Majorana bound states; Physics and Astronomy;

    Sammanfattning : This thesis concerns the creation of Majorana bound states (MBSs) -- a type of condensed matter excitations theorized to have exotic and technologically valuable properties. In particular, they could be used to store and manipulate quantum information in a protected way, forming the building blocks of a topological quantum computer. LÄS MER

  5. 4. 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

  7. 5. Competing phases of matter: Experimental spectroscopy study of the transition metal dichalcogenides Fe-doped TaS2 and Cu-intercalated TiSe2

    Master-uppsats, Uppsala universitet/Institutionen för fysik och astronomi

    Författare :Christian Stefan Gruber; [2023]
    Nyckelord :Condensed matter physics; transition metal dichalcogenides; photoemission spectroscopy;

    Sammanfattning : Syftet med denna avhandling är att bidra till forskningen av befintliga TMD:er (på Engelska transition metal dichalcogenide-TMD) som visar laddningstäthetsvågor och supraledning vid låga temperaturer (som 2H-TaS2). 2H-TaS2 är också känt för att visa supraledning vid 2K. LÄS MER
