  1. 1. Rotational Properties of Lee-Huang-Yang Bosonic Condensates from One to Two Dimensions

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

    Författare :Hjalmar Holmström; [2022]
    Nyckelord :BEC; Bose-Einstein condensate; quantum fluid; Quantum mechanics; LHY; LHY-fluid; Lee-Huang-Yang; Rotating BEC; BEC droplet; Physics and Astronomy;

    Sammanfattning : This thesis covers the work of a numerical examination of the rotational properties of a two-component Bose-Einstein condensate (BEC) utilizing the beyond mean-field extended Gross-Pitaevskii equation for a specified set of parameters. These parameters are chosen to cancel the strength of the mean-field interaction, which makes the system predominantly governed by the next order beyond the mean-field Lee-Huang-Yang (LHY) term.

  3. 2. Chemotaxis in E.coli Bacteria

    Master-uppsats, KTH/Matematik (Avd.)

    Författare :Fredrik Stenkvist; [2021]
    Nyckelord :;

    Sammanfattning : Bacterial chemotaxis refers to bacteria's way of moving towards more hospitable environment. The bacteria does this by taking point-wise measurements of the amount of chemical attractants/repellents in its surroundings and comparing them, using the bacteria's built in "memory" the methylation level, to determine if the current direction is good or not.

  4. 3. Reversing the flow of heat in system of initially correlated qubits

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

    Författare :Giovanni Francesco Diotallevi; Peter Samuelsson; Faraj Bakhshinezhad; [2021]
    Nyckelord :Qubits; Cooling; Heat Flow; Physics and Astronomy;

    Sammanfattning : The Second Law of Thermodynamics is considered to be one of the most fundamental and important laws of Physics. Both Clausius and Kelvin reformulated the Second Law as statements concerning the behaviour of two communicating systems, set to interact at different temperatures. LÄS MER

  5. 4. Solving the Schrödinger equation with artificial neural networks

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

    Författare :Ibrohim Hamoud; [2021]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Deep Learning Solves the Schrödinger Equation, a Fundamental Problem in Quantum Mechanics. The Schrödinger equation (SE) is a keystone of quantum physics, and it governs all phenomena of the microscopic world. LÄS MER

  7. 5. Bottenskikt i förändring : marklav efter avverkning

    Kandidat-uppsats, SLU/Dept. of Wildlife, Fish and Environmental Studies

    Författare :Ester Andersson; Simon Lind; [2020]
    Nyckelord :renskötsel; skogsbruk; samverkan; påverkan; Cladonia spp.;

    Sammanfattning : Skogsbruk och renskötsel är två olika näringar som i dagsläget verkar på samma marker. Renskötseln använder marken för bete samtidigt som skogsbruket producerar förnybara råvaror i form av träprodukter från skogen. LÄS MER
