  1. 21. Diffusion MRI of Brain Tissue: Importance of Axonal Trajectory

    Master-uppsats, Lunds universitet/Fysiska institutionen; Lunds universitet/Kärnfysik

    Författare :Jan Brabec; [2018]
    Nyckelord :dMRI; diffusion magnetic resonance; axonal trajectory; axonal geometry; undulations; modeling; axons; inverse problem; diffusion spectrum; time-dependent diffusion; Physics and Astronomy;

    Sammanfattning : Obtaining microstructural information non-invasively on brain tissue remains a challenge. Diffusion magnetic resonance imaging (dMRI) is an imaging method that can provide such information. That includes geometrical considerations of nerve cells projections, axons, that are present in the white matter of the human brain. LÄS MER

  3. 22. Circuit QED devices for probing Majorana zero modes

    Master-uppsats, Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

    Författare :Oscar Erlandsson; [2018]
    Nyckelord :Physics and Astronomy;

    Sammanfattning : Theoretical understanding indicates that Majorana zero modes in solid-state systems could be utilized for fault-tolerant quantum information processing. The ability to reliably detect these excitations, however, remains a challenge and many of their properties are still unknown. LÄS MER

  4. 23. Near-local density approximation approach to one-dimensional lattice systems

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

    Sammanfattning : After the discovery of graphene in 2004, a single layer of graphite, the assembly of 2D materials became a promising research area in solid state Physics. This thesis explores fabrication of 2D-heterostructures that aim to probe into graphene’s electronic structure with the Tunneling Field Effect Transistor (TFET). LÄS MER
