  1. 1. The Neural Effects Of Mindfulness Interventions On Depression : A Systematic Review

    Kandidat-uppsats, Högskolan i Skövde/Institutionen för biovetenskap

    Författare :Sofia Eriksson; [2023]
    Nyckelord :mindfulness-interventions; depression; functional magnetic resonance imaging; electroencephalography;

    Sammanfattning : Depression has increased among adolescents and adults over the last decade. Effective treatments and techniques to improve personal well being and disorders like depression are much needed. LÄS MER

  3. 2. Electron-skyrmion systems, in and out of equilibrium, and isolated or contacted to reservoirs

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

    Författare :Emil Adam Jonatan Östberg; [2023]
    Nyckelord :skyrmion; skyrmions; NEGF; freen s function; quantum transport; non-equlibrium; topology; topological charge; skyrmionics; current induced; open system; Physics and Astronomy;

    Sammanfattning : A Kondo lattice skyrmion model in contact with a macroscopic environment is simulated to explore skyrmion dynamics, which is an extension of previous work. The system is simulated using non-equilibrium Green's functions within the generalized Kadanoff-Baym ansatz and the wide band limit. LÄS MER

  4. 3. Superluminous magnons in Nickel Oxide

    Master-uppsats, Uppsala universitet/Materialteori

    Författare :Jannes van Poppelen; [2023]
    Nyckelord :;

    Sammanfattning : Recent experiments have shown that the magnon velocity over nanoscale distancesin certain antiferromagnetic materials, with NiO in particular, far exceeds the previous theoretical maximum. Antiferromagnetic insulators are excellent candidatesfor spintronic nanodevices due to their exceptionally low energy dissipation, whichcould benefit the future speed at which information is stored.

  5. 4. Constraining the Higgs width in Higgs production associated with a top quark pair

    Kandidat-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Teoretisk partikelfysik - Geonomgår omorganisation

    Författare :Benjamin Dahlén; [2023]
    Nyckelord :Higgs; width; cross section; on-shell; off-shell; invariant mass; Standard model; upper bound; Physics and Astronomy;

    Sammanfattning : In this thesis we study the width of the Higgs boson in the process pp → t ̄t 4l at LO using MadGraph5_aMC@NLO to generate the events. The contributions including the Higgs signal, continuum background and interference were considered in order to calculate the expected number of events in a broad range of four-lepton invariant masses.

  7. 5. The Stern-Gerlach Spectrometer for Charged Particles : A step towards an alternative method for measuring spin

    Kandidat-uppsats, Lunds universitet/Synkrotronljusfysik; Lunds universitet/Fysiska institutionen

    Författare :Samuel Eriksson; [2023]
    Nyckelord :Stern-Gerlach; Stern; Gerlach; spin; time-of-flight; time of flight; magnetic moment; spectrometer; Physics and Astronomy;

    Sammanfattning : The purpose of this project is to investigate the performance of a spectrometer capable of measuring both momentum and spin of particles. More specifically, we investigated what parameters are required in order to separate particles with opposite spins at least 1 mm. LÄS MER
