    Master-uppsats, KTH/Tillämpad fysik

    Författare :Gaia Di Berardino; [2022]
    Nyckelord :LiTi2O4; anomalous superconductivity; density functional theory; ARPES; electronic band structure; PLD; condensed matter physics; material science; LiTi2O4; okonventionell supraledning; funktionell densitetsteori; ARPES; elektronisk bandstruktur; PLD; kondenserade materiens fysik; materialvetenskap;

    Sammanfattning : This master’s thesis focuses on investigating the electronic properties of the superconducting spinel compound LiTi2O4 by means of computational and experimental effort. The title compound has been extensively studied in the past years, being the only known superconducting spinel oxide with relatively high Tc = 11.5 K. LÄS MER

  3. 17. An Ion-Selective Electrode for Detection of Ammonium in Wastewater Treatment Plants

    Master-uppsats, KTH/Kemi

    Författare :Josephine Berg; [2021]
    Nyckelord :jonselektiv elektrod; membran; ammonium; sensor; reningsverk; ion-selective electrode ISE ; membrane; ammonium; sensor; wastewater treatment plant WWTP ;

    Sammanfattning : Att följa ammonium i reningsverk är avgörande för att förbättra reningsprocessen och kontrollera flödet av föroreningar ut till ekosystemet. Jonselektiva elektroder (ion-selective electrodes, ISEs) är en lovande teknik inom området, där polymermembran baserade på nonactin är de mest studerade membranen för ammoniumsensorer. LÄS MER

  4. 18. Machine-Learning for Lattice Models in and out of Equilibrium

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

    Författare :Johannes Sandberg; [2021]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Machine-learning methods have in recent years seen a great deal of use in condensed matter physics. In this thesis we apply such methods, specifically machine-learning with artificial neural networks, to the equilibrium and non-equilibrium description of the Hubbard and Hubbard-Holstein models.

  5. 19. Exploring the Potential for Machine Learning Techniques to Aid in Categorizing Electron Trajectories during Magnetic Reconnection

    Kandidat-uppsats, KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Författare :Måns Nyman; Caner Naim Ulug; [2020]
    Nyckelord :;

    Sammanfattning : Magnetic reconnection determines the space weather which has a direct impact on our contemporary technological systems. As such, the phenomenon has serious ramifications on humans. Magnetic reconnection is a topic which has been studied for a long time, yet still many aspects surrounding the phenomenon remain unexplored. LÄS MER

  7. 20. Neutrino oscillations at very high energy/matter density

    Master-uppsats, KTH/Fysik

    Författare :Mathilde Guillaud; [2020]
    Nyckelord :Theoretical Physics; Neutrino Oscillations; Astrophysical Neutrinos; Teoretisk fysik; Neutrinooscillationer; Astrofysiska neutriner;

    Sammanfattning : Neutrino oscillations in matter can be studied in different regimes, depending on the energy of the incoming neutrinos and the matter density of the medium. In this thesis we investigate neutrino oscillations in dense matter at very high energy (TeV-PeV range), taking into account the absorption that the neutrinos may undergo in such dense media. LÄS MER
